Leap of imagination: how February 29 reminds us of our mysterious relationship with time and space

<p><em><a href="https://theconversation.com/profiles/emily-ohara-874665">Emily O'Hara</a>, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a></em></p> <p>If you find it intriguing that February 28 will be followed this week by February 29, rather than March 1 as it usually is, spare a thought for those alive in 1582. Back then, Thursday October 4 was followed by Friday October 15.</p> <p>Ten whole days were snatched from the present when Pope Gregory XIII issued a papal bull to “restore” the calendar from discrepancies that had crept into the Julian calendar, introduced by Julius Caesar in 45 BCE.</p> <p>The new Gregorian calendar returned the northern hemisphere’s vernal equinox to its “proper” place, around March 21. (The equinox is when the Earth’s axis is tilted neither toward nor away from the sun, and is used to determine the date of Easter.)</p> <p>The Julian calendar had observed a leap year every four years, but this meant time had drifted out of alignment with the dates of celestial events and astronomical seasons.</p> <p>In the Gregorian calendar, leap days were added only to years that were a multiple of four – like 2024 – with an exception for years that were evenly divisible by 100, but not 400 – like 1700.</p> <p>Simply put, leap days exist because it doesn’t take a neat 365 days for Earth to orbit the Sun. It takes 365.2422 days. Tracking the movement of celestial objects through space in an orderly pattern doesn’t quite work, which is why we have February – time’s great mop.</p> <h2>Time and space</h2> <p>This is just part of the history of how February – the shortest month, and originally the last month in the Roman calendar – came to have the job of absorbing those inconsistencies in the temporal calculations of the world’s most commonly used calendar.</p> <p>There is plenty of <a href="https://theconversation.com/leap-day-fixing-the-faults-in-our-stars-54032">science</a>, <a href="https://theconversation.com/explainer-the-science-behind-leap-years-and-how-they-work-54788">maths</a> and <a href="https://theconversation.com/how-a-seasonal-snarl-up-in-the-mid-1500s-gave-us-our-strange-rules-for-leap-years-132659">astrophysics</a> explaining the relationship between time and the planet we live on. But I like to think leap years and days offer something even more interesting to consider: why do we have calendars anyway?</p> <p>And what have they got to do with how we understand the wonder and strangeness of our existence in the universe? Because calendars tell a story, not just about time, but also about space.</p> <p>Our reckoning of time on Earth is through our spatial relationship to the Sun, Moon and stars. Time, and its place in our lives, sits somewhere between the scientific, the celestial and the spiritual.</p> <p>It is <a href="https://shop.whitechapelgallery.org/products/time">notoriously slippery, subjective and experiential</a>. It is also marked, tracked and determined in myriad ways across different cultures, from tropical to solar to <a href="https://www.stuff.co.nz/pou-tiaki/300062097/matariki-and-the-maramataka-the-mori-lunar-calendar">lunar</a> calendars.</p> <p>It is the Sun that measures a day and gives us our first reference point for understanding time. But it is the <a href="https://librarysearch.aut.ac.nz/vufind/Record/1145999?sid=25214690">Moon</a>, as a major celestial body, that extends our perception of time. By stretching a span of one day into something longer, it offers us a chance for philosophical reflection.</p> <p>The Sun (or its effect at least) is either present or not present. The Moon, however, goes through phases of transformation. It appears and disappears, changing shape and hinting that one night is not exactly like the one before or after.</p> <p>The Moon also has a distinct rhythm that can be tracked and understood as a pattern, giving us another sense of duration. Time is just that – overlapping durations: instants, seconds, minutes, hours, days, weeks, months, years, decades, lifetimes, centuries, ages.</p> <h2>The elusive Moon</h2> <p>It is almost impossible to imagine how time might feel in the absence of all the tools and gadgets we use to track, control and corral it. But it’s also hard to know what we might do in the absence of time as a unit of productivity – a measurable, dispensable resource.</p> <p>The closest we might come is simply to imagine what life might feel like in the absence of the Moon. Each day would rise and fall, in a rhythm of its own, but without visible reference to anything else. Just endless shifts from light to dark.</p> <p>Nights would be almost completely dark without the light of the Moon. Only stars at a much further distance would puncture the inky sky. The world around us would change – trees would grow, mammals would age and die, land masses would shift and change – but all would happen in an endless cycle of sunrise to sunset.</p> <p>The light from the Sun takes <a href="https://www.skyatnightmagazine.com/space-science/how-take-light-from-sun-reach-earth">eight minutes</a> to reach Earth, so the sunlight we see is always eight minutes in the past.</p> <p>I remember sitting outside when I first learned this, and wondering what the temporal delay might be between me and other objects: a plum tree, trees at the end of the street, hills in the distance, light on the horizon when looking out over the ocean, stars in the night sky.</p> <p>Moonlight, for reference, takes about <a href="https://www.pbs.org/seeinginthedark/astronomy-topics/light-as-a-cosmic-time-machine.html">1.3 seconds</a> to get to Earth. Light always travels at the same speed, it is entirely constant. The differing duration between how long it takes for sunlight or moonlight to reach the Earth is determined by the space in between.</p> <p>Time on the other hand, is anything but constant. There are countless ways we characterise it. The mere fact we have so many calendars and ways of describing perceptual time hints at our inability to pin it down.</p> <p>Calendars give us the impression we can, and have, made time predictable and understandable. Leap years, days and seconds serve as a periodic reminder that we haven’t.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/224503/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/emily-ohara-874665"><em>Emily O'Hara</em></a><em>, Senior Lecturer, Spatial Design + Temporary Practices, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“Bloody ripper of a meteor” lights up Perth skies

<p>A few lucky Western Australians have witnessed the moment a bright green meteor flashed brightly across the state's South West.</p> <p>The meteor was the size of a cricket ball and had a 200-kilometre-long tail, which was first spotted at around 8.50pm on Wednesday after entering the atmosphere over Pemberton.</p> <p>The rare spectacle, which only happens around three times a year, lasted about five seconds and travelled at a speed of 30 km/h before the mix of iron, rock and ice dissolved over the Southern Ocean. </p> <p>“Iron meteors give off that beautiful green glow,” Perth Observatory spokesperson Matt Woods told <em>7NEWS</em>.</p> <p>Experts also said that this was triggered by the outer layer of the meteor melting because of intense friction.</p> <p>The observatory said that the meteor had set off a flood of messages, emails and calls from the people that witnessed the natural phenomenon. </p> <p>“That was a bloody ripper of a meteor tonight,” they posted on their Facebook page. </p> <p>One witness said that you had to see it with your own eyes to fully appreciate its beauty. </p> <p>“I will say it was way better in person. It looked almost rainbow-coloured. Just spectacular,” commented one person. </p> <p>“Did anyone just see a bright streak of light shooting from the sky? It was too bright to be a shooting star,” another person shared on social media. </p> <p>“It was massive and extremely bright.”</p> <p><em>Image: 7NEWS</em></p> <p> </p>

Domestic Travel

Almost half of Moon missions fail. Why is space still so hard?

<p><em><a href="https://theconversation.com/profiles/gail-iles-761554">Gail Iles</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>In 2019, India attempted to land a spacecraft on the Moon – and ended up painting a kilometres-long streak of debris on its barren surface. Now the Indian Space Research Organisation has returned in triumph, with the Chandrayaan-3 lander <a href="https://www.reuters.com/world/india/india-counts-down-crucial-moon-landing-2023-08-23/">successfully touching down</a> near the south pole of Earth’s rocky neighbour.</p> <p>India’s success came just days after a <a href="https://www.nature.com/articles/d41586-023-02659-6">spectacular Russian failure</a>, when the Luna 25 mission tried to land nearby and “ceased to exist as a result of a collision with the lunar surface”.</p> <p>These twin missions remind us that, close to 60 years after the first successful “soft landing” on the Moon, spaceflight is still difficult and dangerous. Moon missions in particular are still a coin flip, and we have seen several high-profile failures in recent years.</p> <p>Why were these missions unsuccessful and why did they fail? Is there a secret to the success of countries and agencies who have achieved a space mission triumph?</p> <h2>An exclusive club</h2> <p>The Moon is the only celestial location humans have visited (so far). It makes sense to go there first: it’s the closest planetary body to us, at a distance of around 400,000 kilometres.</p> <p>Yet only four countries have achieved successful “soft landings” – landings which the spacecraft survives – on the lunar surface.</p> <p>The USSR was the first. The <a href="https://en.wikipedia.org/wiki/Luna_9">Luna 9</a> mission safely touched down on the Moon almost 60 years ago, in February 1966. The United States followed suit a few months later, in June 1966, with the <a href="https://www.smithsonianmag.com/air-space-magazine/1966-the-real-first-moon-landing-118785850/">Surveyor 1</a> mission.</p> <p>China was the next country to join the club, with the <a href="https://en.wikipedia.org/wiki/Chang%27e_3">Chang'e 3</a> mission in 2013. And now India too has arrived, with <a href="https://amp.theguardian.com/science/2023/aug/23/india-chandrayaan-3-moon-landing-mission">Chandrayaan-3</a>.</p> <p>Missions from Japan, the United Arab Emirates, Israel, Russia, the European Space Agency, Luxembourg, South Korea and Italy have also had <a href="https://en.wikipedia.org/wiki/List_of_missions_to_the_Moon">some measure of lunar success</a> with fly-bys, orbiters and impacts (whether intentional or not).</p> <h2>Crashes are not uncommon</h2> <p>On August 19 2023, the Russian space agency Roscosmos announced that “communication with the <a href="https://www.nature.com/articles/d41586-023-02659-6">Luna 25 spacecraft</a> was interrupted”, after an impulse command was sent to the spacecraft to lower its orbit around the Moon. Attempts to contact the spacecraft on August 20 were unsuccessful, leading Roscosmos to determine Luna 25 had crashed.</p> <p>Despite more than 60 years of spaceflight experience extending from the USSR to modern Russia, this mission failed. We don’t know exactly what happened – but the current situation in Russia, where resources are stretched thin and tensions are high due to the ongoing war in Ukraine, may well have been a factor.</p> <p>The Luna 25 failure recalled two high-profile lunar crashes in 2019.</p> <p>In April that year, the Israeli <a href="https://en.wikipedia.org/wiki/Beresheet">Beresheet lander</a> crash-landed after a gyroscope failed during the braking procedure, and the ground control crew was unable to reset the component due to a loss of communications. It was later reported a capsule containing microscopic creatures called tardigrades, in a dormant “cryptobiotic” state, may have survived the crash.</p> <p>And in September, India sent its own Vikram lander down to the surface of the Moon – but it did not survive the landing. NASA later <a href="https://www.theguardian.com/science/2019/dec/03/indias-crashed-vikram-moon-lander-spotted-on-lunar-surface">released an image</a> taken by its Lunar Reconnaissance Orbiter showing the site of the Vikram lander’s impact. Debris was scattered over almost two dozen locations spanning several kilometres.</p> <h2>Space is still risky</h2> <p>Space missions are a risky business. Just over <a href="https://www.businessinsider.in/science/space/news/success-rate-of-lunar-missions-is-a-little-over-50-as-per-nasa-database/articleshow/101774227.cms">50% of lunar missions succeed</a>. Even <a href="https://ntrs.nasa.gov/api/citations/20190002705/downloads/20190002705.pdf">small satellite missions</a> to Earth’s orbit don’t have a perfect track record, with a success rate somewhere between 40% and 70%.</p> <p>We could compare uncrewed with crewed missions: around <a href="https://www.bbc.com/future/article/20230518-what-are-the-odds-of-a-successful-space-launch">98% of the latter are successful</a>, because people are more invested in people. Ground staff working to support a crewed mission will be more focused, management will invest more resources, and delays will be accepted to prioritise the safety of the crew.</p> <p>We could talk about the details of why so many uncrewed missions fail. We could talk about technological difficulties, lack of experience, and even the political landscapes of individual countries.</p> <p>But perhaps it’s better to step back from the details of individual missions and look at averages, to see the overall picture more clearly.</p> <h2>The big picture</h2> <p>Rocket launches and space launches are not very common in the scheme of things. There are <a href="https://www.pd.com.au/blogs/how-many-cars-in-the-world/">around 1.5 billion cars</a> in the world, and perhaps <a href="https://www.travelweek.ca/news/exactly-many-planes-world-today/">40,000 aeroplanes</a>. By contrast, there have been fewer than <a href="https://planet4589.org/space/gcat/data/derived/launchlog.html">20,000 space launches</a> in all of history.</p> <p>Plenty of things still go wrong with cars, and problems occur even in the better-regulated world of planes, from loose rivets to computers overriding pilot inputs. And we have more than a century of experience with these vehicles, in every country on the planet.</p> <p>So perhaps it’s unrealistic to expect spaceflight – whether it’s the launch stage of rockets, or the even rarer stage of trying to land on an alien world – to have ironed out all its problems.</p> <p>We are still very much in the early, pioneering days of space exploration.</p> <h2>Monumental challenges remain</h2> <p>If humanity is ever to create a fully fledged space-faring civilisation, we must <a href="https://www.wired.com/2016/02/space-is-cold-vast-and-deadly-humans-will-explore-it-anyway/">overcome monumental challenges</a>.</p> <p>To make long-duration, long-distance space travel possible, there are a huge number of problems to be solved. Some of them seem within the realm of the possible, such as better radiation shielding, self-sustaining ecosystems, autonomous robots, extracting air and water from raw resources, and zero-gravity manufacturing. Others are still speculative hopes, such as faster-than-light travel, instantaneous communication, and artificial gravity.</p> <p>Progress will be little by little, small step by slightly larger step. Engineers and space enthusiasts will keep putting their brainpower, time and energy into space missions, and they will gradually become more reliable.</p> <p>And maybe one day we’ll see a time when going for a ride in your spacecraft is as safe as getting in your car.</p> <hr /> <p><em>Correction: a typing error in the original version of this article put the Surveyor 1 mission in 1996, rather than its actual year of 1966.</em><img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/211914/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/gail-iles-761554">Gail Iles</a>, Senior Lecturer in Physics, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

International Travel

Mystery object washed up on WA beach finally identified

<p>Ok space enthusiasts and beachcombers. Here's one for the X-Files – Intergalactic Travel edition.</p> <p>Picture this: A strange and baffling object, looking like it's straight out of a sci-fi flick, decided to take a little trip to Green Head beach, about 250 kilometres north of Perth on the pristine WA coastline.</p> <p>As soon as the locals caught sight of this extraterrestrial-looking thingamajig, the news spread like wildfire, and it made international headlines faster than a speeding rocket, with all kinds of fascinating theories popping up as to what on <em>Earth</em> (or not on Earth) it could be.</p> <p>Was it a UFO? A top-secret government experiment gone awry? Well, turns out it was nothing that exciting. The Australian Space Agency put on their Sherlock Holmes hats and deduced that this enigmatic piece of debris probably came from a satellite launch vehicle. Eureka! Case closed!</p> <p>Of course, when something weird and otherworldly shows up on your doorstep, you can't be too careful. So, the local authorities played it safe and put the object under police guard for an entire week. (Better safe than sorry, right?)</p> <p>And who needs a red carpet when you have a front-end loader to transport your newfound cosmic artifact? The experts were summoned to figure out where this space junk came from, and they concluded it was most likely a fuel tank from some rocket launched by the Indian Space Research Organisation. </p> <p>Professor Alice Gorman from Flinders University explained to <a href="https://www.abc.net.au/news/2023-07-31/australian-space-agency-identifies-space-junk-green-head/102669472" target="_blank" rel="noopener">ABC News</a> that this fuel containment vessel was meant to fall off after launch. And it turns out that statistically, we've been pretty lucky not to have had more collisions with falling rocket parts. Imagine explaining that to your insurance company? "A rocket booster landed on my house. Is that covered?"</p> <p>But here comes the tricky part: What to do with all of this space garbage? Should they ship it back to India like some interstellar postcard, or leave it Down Under as an intergalactic souvenir?</p> <p>While India is technically (and legally) responsible for their space debris, they could decide to gift it to Australia if they so choose. It could be like an exotic space decoration for the country - "The Land of Kangaroos and Rocket Wreckage."</p> <p>Even better, the Green Head community itself appear to have come up with a few fabulous ideas. Forget the Sydney Opera House: let's make the space debris a tourist attraction! Move over, Eiffel Tower - we've got our own piece of space history right here.</p> <p>The WA Premier even suggested storing it next to space debris from NASA's Skylab space station (remember that?) in some kind of attempt to build a cosmic cabinet of curiosities. </p> <p>Of course, the local council is also very keen on keeping this celestial treasure. They're hoping the Indian government won't come back to claim it, to the point that everyone in the surrounding Shire of Coorow is buzzing with excitement over the possibility of having their very own space souvenir to draw crowds of star trekkers.</p> <p>And so while the mystery of the object on the beach has been solved, the debate over its fate is just beginning. Will it become a star attraction in a local park? Or will it be shipped off to India like an interplanetary package return? Only time will tell.</p> <p><em>Images: Nine News</em></p>

Travel Trouble

2001: A Space Odyssey still leaves an indelible mark on our culture 55 years on

<p><em><a href="https://theconversation.com/profiles/nathan-abrams-122305">Nathan Abrams</a>, <a href="https://theconversation.com/institutions/bangor-university-1221">Bangor University</a></em></p> <p>2001: A Space Odyssey is a landmark film in the history of cinema. It is a work of extraordinary imagination that has transcended film history to become something of a cultural marker. And since 1968, it has penetrated the psyche of not only other filmmakers but society in general.</p> <p>It is not an exaggeration to say that 2001 single-handedly reinvented the science fiction genre. The visuals, music and themes of 2001 left an inedible mark on subsequent science fiction that is still evident today.</p> <p>When <a href="https://www.simonandschuster.com/books/Kubrick/Robert-P-Kolker/9781639366248">Stanley Kubrick</a> began work on 2001 in the mid-1960s, he was told by studio executive Lew Wasserman: “Kid, you don’t spend over a million dollars on science fiction movies. You just don’t do that.”</p> <p>By that point, the golden age of science fiction film had run its course. During its heyday, there was a considerable variety of content within the overarching genre. There had been serious attempts to foretell space travel. Destination Moon, directed by Irving Pichel and produced by George Pal in 1950, and, in mid-century, Byron Haskin’s Conquest of Space both fantasised space travel and, in Haskin’s film, a space station, which Kubrick would elaborate on in 2001.</p> <figure><iframe src="https://www.youtube.com/embed/oR_e9y-bka0?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">The trailer for 2001: A Space Odyssey.</span></figcaption></figure> <p>Most 1950s science fiction films, though, were cheap B-movie fare and looked it. They involved alien invasions with an ideological and allegorical subtext. They were cultural, cinematic imaginations of the danger of communism, which in the overheated political atmosphere of the time was seen as an imminent threat to the American way of life.</p> <p>The aliens in most science fiction films were out simply to destroy or take over humanity; they were expressions, to use the title of a Susan Sontag essay, of “<a href="https://americanfuturesiup.files.wordpress.com/2013/01/sontag-the-imagination-of-disaster.pdf">the imagination of disaster</a>”. There were some exceptions, including Byron Haskin’s film version of The War of the Worlds and Robert Wise’s The Day the Earth Stood Still.</p> <p>By 1968, then, as the lights went down, very few people knew what was about to transpire and they certainly were not prepared for what did. The film opened in near darkness as the strains of Thus Spake Zarathustra by Richard Strauss were heard. The cinema was dazzled into light, as if Kubrick had <a href="https://www.rutgersuniversitypress.org/stanley-kubrick/9780813587110">remade Genesis</a>.</p> <p>The subsequent 160 or so minutes (the length of his original cut before he edited 19 minutes out of it) took the viewer on what was marketed as “the ultimate trip”. Kubrick had excised almost every element of explanation leaving an elusive, ambiguous and thoroughly unclear film. His decisions contributed to long silent scenes, offered without elucidation. It contributed to the film’s almost immediate critical failure but its ultimate success. It was practically a silent movie.</p> <p>2001 was an experiment in film form and content. It exploded the conventional narrative form, restructuring the conventions of the three-act drama. The narrative was linear, but radically, spanning aeons and ending in a timeless realm, all without a conventional movie score. Kubrick used 19th-century and modernist music, such as Strauss, György Ligeti and Aram Khachaturian.</p> <h2>Vietnam</h2> <p>The movie was made during a tumultuous period of American history, which it seemingly ignored. The war in Vietnam was already a highly divisive issue and was spiralling into a crisis. The <a href="https://www.britannica.com/topic/Tet-Offensive">Tet offensive</a>, which began on January 31 1968, had claimed tens of thousands of lives. As US involvement in Vietnam escalated, domestic unrest and violence at home intensified.</p> <p>Increasingly, young Americans expected their artists to address the chaos that roared around them. But in exploring the origins of humanity’s propensity for violence and its future destiny, 2001 dealt with the big questions and ones that were burning at the time of its release. They fuelled what Variety magazine called the “coffee cup debate” over “what the film means”, which is still ongoing today.</p> <p>The design of the film has touched many other films. Silent Running by Douglas Trumbull (who worked on 2001’s special effects) owes the most obvious debt but Star Wars would be also unthinkable without it. Popular culture is full of imagery from the film. The <a href="https://faroutmagazine.co.uk/stanley-kubrick-2001-a-space-odyssey-music/">music</a> Kubrick used in the film, especially Strauss’s The Blue Danube, is now considered <a href="https://theweek.com/articles/702734/planetarium-brief-history-space-music">“space music”</a>.</p> <p>Images from the movie have appeared <a href="https://www.youtube.com/watch?v=kfK9pEQZyy0">in iPhone adverts</a>, in The Simpsons and even the trailer for the new <a href="https://metro.co.uk/2022/12/16/trailer-for-greta-gerwigs-barbie-spoofs-classic-film-in-best-way-17951854/">Barbie movie</a>.</p> <figure><iframe src="https://www.youtube.com/embed/8zIf0XvoL9Y?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">2001: A Space Odyssey’s influence on this Barbie movie trailer couldn’t be more obvious.</span></figcaption></figure> <p>The warnings of the danger of technology embodied in the film’s murderous supercomputer HAL-9000 can be felt in the “tech noir” films of the late 1970s and 1980s, such as Westworld, <a href="https://theconversation.com/how-alien-mutated-from-a-sci-fi-horror-film-into-a-multimedia-universe-204567">Alien</a>, Blade Runner and Terminator.</p> <p>HAL’s single red eye can be seen in the children’s series, Q Pootle 5, and Pixar’s animated feature, Wall-E.

Virgin Galactic’s use of the ‘Overview Effect’ to promote space tourism is a terrible irony

<p><a href="https://theconversation.com/profiles/ariane-moore-1060920">Ariane Moore</a>, <em><a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p>Virgin Galactic, the space tourism company founded in 2004 by Richard Branson, <a href="https://www.virgingalactic.com/">promotes its flights</a> as offering:</p> <blockquote> <p>A Brand New Perspective: Deepen your connection to Earth and to humanity with the transformational experience known as the Overview Effect.</p> </blockquote> <p>First discussed in 1987 by space philosopher Frank White, the Overview Effect is a result of viewing Earth from space.</p> <p>Expressions of the effect range broadly. Astronauts might experience profound awe and wonder at the perception of Earth as a fragile living being. Some suffer crushing grief when considering the harm humans inflict on nature.</p> <p>While Virgin Galactic promotes access to the Overview Effect as a major drawcard, it is a terrible irony that space tourism is <a href="https://www.thespacereview.com/article/4527/1">enormously damaging</a> for the environment.</p> <figure><iframe src="https://www.youtube.com/embed/Z6d7hyW5FDw?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">On May 25, Virgin Galactic completed a final test flight before it starts taking paying customers.</span></figcaption></figure> <h2>The Overview Effect</h2> <p>The Overview Effect is not limited to astronauts from the West. Their Chinese and Russian counterparts have described the same profound connection to Earth when witnessing the planet from space.</p> <p>As Soviet Russian cosmonaut Yuri Artyushkin <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fcns0000086">reported</a>:</p> <blockquote> <p>The feeling of unity is not simply an observation. With it comes a strong sense of compassion and concern for the state of our planet and the effect humans are having on it. It isn’t important in which sea or lake you observe a slick of pollution, or in the forests of which country a fire breaks out, or on which continent a hurricane arises. You are standing guard over the whole of our Earth.</p> </blockquote> <p>Until recently, researching the Overview Effect has required interviews with professional astronauts. Today, commercial space tourism is increasing awareness of the phenomenon, particularly when experienced by celebrities with large platforms.</p> <p>In 2021, Star Trek actor William Shatner completed a suborbital flight with Jeff Bezos’ space tourism company <a href="https://www.blueorigin.com/">Blue Origin</a>. Shatner had anticipated emotions of celebration and joy when viewing “<a href="https://www.nytimes.com/2021/10/13/science/bezos-shatner-star-trek.html">mother and Earth and comfort</a>” from space. Instead, he <a href="https://variety.com/2022/tv/news/william-shatner-space-boldly-go-excerpt-1235395113/">later wrote</a>, he struggled with “the strongest feelings of grief I have ever encountered”.</p> <p>Shatner attributed his experience to the Overview Effect.</p> <h2>Space flight has a huge environmental impact</h2> <p>Virgin Galactic promotes the Overview Effect on its <a href="https://www.virgingalactic.com/">homepage</a> as an experience exclusive to space flight.</p> <p>However, access is extremely costly. While an eager space tourist consents to parting with US$450,000 to experience a profound connection with Earth, the planet itself has no say in receiving the massive pollution a single trip produces.</p> <p>Rocket emissions impact Earth’s atmosphere, temperatures and the ozone layer at an unprecedented level. A <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2021EF002612">2022 study</a> found space tourism produces black carbon particles that are almost 500 times more efficient at warming the atmosphere than all surface and airline sources of soot combined.</p> <p>After being released into the upper atmosphere, the black carbon particles circulate for <a href="https://www.cnbc.com/2021/08/27/how-blue-origin-spacex-virgin-galactic-space-race-could-impact-the-atmosphere.html#:%7E:text=Experiencing%20a%20few%20minutes%20of,plane%20continuously%20for%20about%20three">four to five years</a> in a fine layer.

However, the latter carries hundreds of passengers. With a passenger limit of six, a Virgin Galactic launch <a href="https://theconversation.com/tourisme-spatial-quand-les-plaisirs-de-quelques-uns-polluent-la-planete-de-tous-146552">emits 4.5 tonnes of carbon <em>per person</em></a>.

As was evident in Shatner’s feelings of immense grief, these emotions are not always pleasant.</p> <p>Instead, researchers, astronauts and space philosophers are interested in the spontaneous and powerful awareness that occurs. Astronauts’ accounts of the moment vary, but a consistent theme emerges: a connection to planet Earth that inspires environmental care.</p> <p>Importantly, such clarity can be achieved without a suborbital space flight.</p> <p><a href="https://www.google.com.au/books/edition/The_Overview_Effect/3a2rz-s3JJsC?hl=en">Frank White argues</a> that, while viewing Earth from space produces the “ultimate” Overview Effect, it might also be had while looking at landscapes from a great height – such as a mountain range. Commercial pilots flying at high altitudes have experienced similar phenomena.</p> <p>And for those considering a Virgin Galactic flight, there are no guarantees. Many astronauts with long careers <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fcns0000086">report</a> never experiencing the Overview Effect.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=600&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=600&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=600&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=755&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=755&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=755&fit=crop&dpr=3 2262w" alt="View of whole Earth photographed by the orbiting Apollo 17 mission and dubbed 'Blue Marble'" /><figcaption><span class="caption">Being able to see the whole Earth from space was regarded as a transformative moment, but people can have environmental epiphanies without flying into space.</span> <span class="attribution"><a class="source" href="https://www.nasa.gov/content/blue-marble-image-of-the-earth-from-apollo-17">NASA/Apollo 17</a></span></figcaption></figure> <h2>Environmental epiphanies happen on Earth</h2> <p>Spontaneous clarity about the importance of nature can occur while standing on solid ground. “<a href="https://www.jstor.org/stable/26506666#:%7E:text=The%20working%20definition%20of%20Environmental,shifts%20in%20a%20meaningful%20manner.">Environmental epiphanies</a>” are well documented and have no connection to specific religious or cultural beliefs.</p> <p>Involving profound emotions and sudden awareness similar to the Overview Effect, environmental epiphanies can be accessed for free in mundane locations – such as reading a book at home.</p> <p>And, like the Overview Effect, environmental epiphanies can lead to lasting change.</p> <p>As space tourism continues to “take off”, misaligned marketing tactics like Virgin Galactic’s promotion of the Overview Effect must be scrutinised.</p> <p>Being launched into space – and the massive pollution the process creates – isn’t necessary for us to want to sustain our Earth.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/206868/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/ariane-moore-1060920">Ariane Moore</a>, PhD Candidate in Philosophy, <em><a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

6 household items to complete your space

<p dir="ltr">Forget perfect furnishings and decorations and focus on the household items that are easy to forget. </p> <p dir="ltr"><strong>1. A comfy seat</strong></p> <p dir="ltr">As basic as it sounds, it is definitely a necessity. We all do a lot of sitting at home so make sure you invest in a nice, comfy chair or fold-out sofa that won’t hurt your back. </p> <p dir="ltr"><strong>2. A lamp</strong></p> <p dir="ltr">Power outages can and do happen, so make sure you’re prepared with a torch or solar-powered lamp. You’ll thank yourself during an emergency!</p> <p dir="ltr"><strong>3. A shower curtain</strong></p> <p dir="ltr">Buy a fresh shower curtain and experiment with different colours. You could also match the colour of your shower curtain, towels and floor mat to really bring the room together. </p> <p dir="ltr"><strong>4. A good mattress</strong></p> <p dir="ltr">This one is so obvious, but have you bought the right size? Is it good quality? You spend around a third of your life asleep, so make sure you get a good one. A mattress should be more of an investment than a simple purchase. </p> <p dir="ltr"><strong>5. Kitchen utensils </strong></p> <p dir="ltr">Prepare yourself to cook! Make sure you have a wooden spoon, a spatula and basic cutlery. Invest in a fry pan and some saucepans too.</p> <p dir="ltr"><strong>6. Potted plants</strong></p> <p dir="ltr">Your home is going to feel fresh and healthy with a few indoor plants around. They will help clean the air and add a little style to your room as well. </p> <p dir="ltr"><em>Image credit: Shutterstock</em></p>

Mental health: how living in the city and country compare

<p>Is it better to live in a city or in the countryside? While urban dwellers may benefit from more employment opportunities, better access to public services alongside cultural activities and entertainment, people who live in rural areas often argue they have a better sense of community and greater access to nature.</p> <p>A number of studies have sought to determine whether city or country is better for mental health by drawing on national survey data from the <a href="https://www.understandingsociety.ac.uk/">UK Household Longitudinal Study</a> (UKHLS). This is a national survey which has followed approximately 40,000 UK households since 2009. Each year, data is collected on a range of social, economic and behavioural factors.</p> <p>This is what some of these studies have found when it comes to mental health and where you live:</p> <h2>Physical activity</h2> <p>Research has shown that physical activity can reduce <a href="https://www.sciencedirect.com/science/article/pii/S0749379719302466?casa_token=_QxDT_feTekAAAAA:Sd_9jfW0ukJY1fUCkUx43sTEGHkNBiwqViPI4-HfSx-LngPhuxBjGMRQrokDmpYlZIwzR7wDzA">anxiety</a> and <a href="https://ajp.psychiatryonline.org/doi/full/10.1176/appi.ajp.2018.17111194">depression</a>, alongside <a href="https://www.tandfonline.com/doi/abs/10.1080/00223980.2018.1470487">improving mood</a> and <a href="https://academic.oup.com/tbm/article-abstract/10/5/1098/5921063?login=true">wellbeing</a>. Indeed, UK health guidelines recommend physical activity for the <a href="https://www.nice.org.uk/guidance/ng222">treatment of depression</a> and <a href="https://www.gov.uk/government/publications/physical-activity-guidelines-adults-and-older-adults/physical-activity-for-adults-and-older-adults-19-and-over-text-of-the-infographic">improved quality of life</a>.</p> <p>One easy way of getting more physical activity in your life is through active travel – such as cycling or walking on your way to work or running errands.</p> <p>So how does urban or rural dwelling impact on this? According to UKHLS research which looked at data from 35,295 people in the UK, urban residents were 64% more likely than rural residents to <a href="https://link.springer.com/article/10.1007/s00038-014-0578-2">engage frequently in active travel</a>. This is likely because there are more active travel opportunities in urban environments where there are shorter distances between facilities, shops, offices and homes.</p> <p>Research shows that the more active travel a person does, the better their <a href="https://www.sciencedirect.com/science/article/pii/S2214140520300487">mental health</a>. In fact, the mental health benefits of active travel may be <a href="https://pubmed.ncbi.nlm.nih.gov/28153647">just as good</a> as physical activity for leisure. So, based on this measure, people living in the city may have better mental health overall.</p> <p>But while urban life may offer more opportunities for active travel compared to living in the countryside, that doesn’t mean there aren’t still many ways to incorporate physical activity into your daily life for mental health benefits wherever you live.</p> <h2>Access to green space</h2> <p>Access to green space (such as parks) is believed to support many aspects of <a href="https://www.nature.com/articles/s41598-019-44097-3">health and wellbeing</a> – including your <a href="https://www.tandfonline.com/doi/abs/10.1080/09638237.2020.1755027?journalCode=ijmh20">mental health</a>.</p> <p>To investigate whether nearby green space was related to mental wellbeing, data from the 2009-2010 UKHLS study was combined with data on the proportion of green space within different areas of England. The analysis found the amount of local green space did not actually <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-017-4401-x">predict mental wellbeing</a>.</p> <p>What this suggests is that while green space may be important for mental wellbeing, having it nearby doesn’t necessarily mean people will engage with it. As such, we can’t assume rural living is inherently more beneficial just because nature is more accessible.</p> <p>This aligns with the findings of a 2021 study, which showed that living near green space <a href="https://www.nature.com/articles/s41598-021-87675-0#Sec2">did not improve mental health outcomes</a>. However, the analysis did find that the more frequently a person visited green spaces, the better their mental wellbeing. <a href="https://www.tandfonline.com/doi/full/10.1080/17439760.2016.1221126">Meaningful engagement with green spaces</a> (such as taking photographs) may also be more important for reaping the mental health benefits of nature.</p> <p>As such, urban living may be just as good as rural dwelling when it comes to the mental health benefits of green space.</p> <h2>Air quality</h2> <p>Numerous studies have found links between high levels of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6447209/">air pollution</a> and <a href="https://www.kcl.ac.uk/news/exposure-to-air-pollution-linked-with-increased-mental-health-service-use-new-study-finds">poorer mental health</a>. A <a href="https://www.sciencedirect.com/science/article/pii/S0161813X22001668?via%253Dihub">review of 111 studies</a> even suggests that polluted air may cause changes in the brain regions that control emotions. This may increase the risk of developing anxiety and depression compared to those who breathe cleaner air.</p> <p>To investigate the impact of air pollution on mental health, researchers combined data on air pollution from the UK Department for Environment, Food and Rural Affairs with UKHLS survey data, alongside data from the British Household Panel Survey (which looked at 10,000 UK households and ran from 1991 to 2009). This allowed them to analyse data from the years 1991-2014.</p> <p>The analysis found that people who were exposed to higher levels of air pollution reported lower levels of <a href="https://www.understandingsociety.ac.uk/research/publications/524260">life satisfaction</a>. The study indicated that the negative effect of air pollution on life satisfaction can be equivalent to major life events, such as divorce.</p> <p>In general, urban areas have between <a href="https://www.thelancet.com/pdfs/journals/lanplh/PIIS2542-5196(21)00255-2.pdf">two to four times the levels of air pollution</a> than rural areas, suggesting people who live in cities may be more likely to experience worse mental health as a result. However, the agricultural industry also generates <a href="https://uk-air.defra.gov.uk/assets/documents/reports/aqeg/2800829_Agricultural_emissions_vfinal2.pdf">high levels of air pollution</a> meaning some rural dwellers in certain settings may also be at risk.</p> <h2>Regional variation in wellbeing</h2> <p>Of course, these are just a few of the factors that affect a person’s day to day mental health – and it appears neither city nor country living is significantly better than the other when it comes to your mental health.</p> <p>Indeed, research has found that the <a href="https://www.tandfonline.com/doi/full/10.1080/00343404.2019.1645953?needAccess=true">region of the country</a> you live in may be more important when it comes to your mental health than whether you live in the city or the countryside. There are many factors that may explain this effect, including the cost of living in certain areas, alongside local politics and a person’s economic status.</p> <p>Where we live is clearly very important when it comes to our mental health. But the place that works best for your mental health will depend largely on broader social and economic factors as well as which aspects of your lifestyle are most important to you.</p> <p><em><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">Image credit: Shutterstock</span></em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/mental-health-how-living-in-the-city-and-country-compare-200402" target="_blank" rel="noopener">The Conversation</a></em><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">.</span></p>

Humans are still hunting for aliens. Here’s how astronomers are looking for life beyond Earth

<p>We have long been fascinated with the idea of alien life. The earliest written record presenting the idea of “aliens” is seen in the satiric work of Assyrian writer <a href="https://blogs.scientificamerican.com/life-unbounded/the-first-alien/">Lucian of Samosata</a> dated to 200 AD.</p> <p>In one novel, Lucian <a href="https://www.yorku.ca/inpar/lucian_true_tale.pdf">writes of a journey to the Moon</a> and the bizarre life he imagines living there – everything from three-headed vultures to fleas the size of elephants.</p> <p>Now, 2,000 years later, we still write stories of epic adventures beyond Earth to meet otherworldly beings (<a href="https://www.britannica.com/topic/The-Hitchhikers-Guide-to-the-Galaxy-novel-by-Adams">Hitchhiker’s Guide</a>, anyone?). Stories like these entertain and inspire, and we are forever trying to find out if science fiction will become science fact.</p> <h2>Not all alien life is the same</h2> <p>When looking for life beyond Earth, we are faced with two possibilities. We might find basic microbial life hiding somewhere in our Solar System; or we will identify signals from intelligent life somewhere far away.</p> <div data-id="17"> </div> <p>Unlike in <a href="https://www.britannica.com/topic/Star-Wars-film-series">Star Wars</a>, we’re not talking far, far away in another galaxy, but rather around other nearby stars. It is this second possibility which really excites me, and should excite you too. A detection of intelligent life would fundamentally change how we see ourselves in the Universe.</p> <p>In the last 80 years, programs dedicated to the search for extraterrestrial intelligence (SETI) have worked tirelessly searching for cosmic “hellos” in the form of radio signals.</p> <p>The reason we think any intelligent life would communicate via radio waves is due to the waves’ ability to travel vast distances through space, rarely interacting with the dust and gas in between stars. If anything out there is trying to communicate, it’s a pretty fair bet they would do it through radio waves.</p> <h2>Listening to the stars</h2> <p>One of the most exciting searches to date is <a href="https://breakthroughinitiatives.org/initiative/1">Breakthrough Listen</a>, the largest scientific research program dedicated to looking for evidence of intelligent life beyond Earth.</p> <p>This is one of many projects funded by US-based Israeli entrepreneurs Julia and Yuri Milner, with some serious dollars attached. Over a ten-year period a total amount of <a href="https://breakthroughinitiatives.org/initiative/1">US$100 million</a> will be invested in this effort, and they have a mighty big task at hand.</p> <p>Breakthrough Listen is currently targeting the closest one million stars in the hope of identifying any unnatural, alien-made radio signals. Using telescopes around the globe, from the 64-metre Murriyang Dish (Parkes) here in Australia, to the 64-antenna MeerKAT array in South Africa, the search is one of epic proportions. But it isn’t the only one.</p> <p>Hiding away in the Cascade Mountains north of San Francisco sits the <a href="https://www.seti.org/ata">Allen Telescope Array</a>, the first radio telescope built from the ground up specifically for SETI use.</p> <p>This unique facility is another exciting project, able to search for signals every day of the year. This project is currently upgrading the hardware and software on the original dish, including the ability to target several stars at once. This is a part of the non-profit research organisation, the SETI Institute.</p> <h2>Space lasers!</h2> <p>The SETI Institute is also looking for signals that would be best explained as “space lasers”.</p> <p>Some astronomers hypothesise that intelligent beings might use massive lasers to communicate or even to propel spacecraft. This is because even here on Earth we’re investigating <a href="https://www.nasa.gov/feature/goddard/2022/the-future-of-laser-communications/">laser communication</a> and laser-propelled <a href="https://www.insidescience.org/news/new-light-sail-design-would-use-laser-beam-ride-space">light sails</a>.</p> <p>To search for these mysterious flashes in the night sky, we need speciality instruments in locations around the globe, which are currently being developed and deployed. This is a research area I’m excited to watch progress and eagerly await results.</p> <p>As of writing this article, sadly no alien laser signals have been found yet.</p> <h2>Out there, somewhere</h2> <p>It’s always interesting to ponder who or what might be living out in the Universe, but there is one problem we must overcome to meet or communicate with aliens. It’s the speed of light.</p> <p>Everything we rely on to communicate via space requires light, and it can only travel so fast. This is where my optimism for finding intelligent life begins to fade. The Universe is big – really big.</p> <p>To put it in perspective, humans started using radio waves to communicate across large distances in 1901. That <a href="https://ethw.org/Milestones:Reception_of_Transatlantic_Radio_Signals,_1901">first transatlantic signal</a> has only travelled 122 light years, reaching just 0.0000015% of the stars in our Milky Way.</p> <p>Did your optimism just fade too? That is okay, because here is the wonderful thing… we don’t have to find life to know it is out there, somewhere.</p> <p>When we consider the <a href="https://theconversation.com/how-many-stars-are-there-in-space-165370">trillions of galaxies</a>, septillion of stars, and likely many more planets just in the observable Universe, it feels near impossible that we are alone.</p> <p>We can’t fully constrain the parameters we need to estimate how many other lifeforms might be out there, as famously proposed by Frank Drake, but using our best estimates and <a href="https://www.cambridge.org/core/journals/international-journal-of-astrobiology/article/numerical-testbed-for-hypotheses-of-extraterrestrial-life-and-intelligence/0C97E7803EEB69323C3728F02BA31AFA">simulations</a> the current best answer to this is tens of thousands of possible civilisations out there.</p> <p>The Universe <a href="https://theconversation.com/is-space-infinite-we-asked-5-experts-165742">might even be infinite</a>, but that is too much for my brain to comprehend on a weekday.</p> <h2>Don’t forget the tiny aliens</h2> <p>So, despite keenly listening for signals, we might not find intelligent life in our lifetimes. But there is hope for aliens yet.</p> <p>The ones hiding in plain sight, on the planetary bodies of our Solar System. In the coming decades we’ll explore the moons of Jupiter and Saturn like never before, with missions hunting to find traces of basic life.</p> <p>Mars will continue to be explored – eventually by humans – which could allow us to uncover and retrieve samples from new and unexplored regions.</p> <p>Even if our future aliens are only tiny microbes, it would still be nice to know we have company in this Universe.</p> <p><em>Images: Getty</em></p> <p><em style="box-sizing: border-box; color: #212529; font-family: -apple-system, 'system-ui', 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji'; font-size: 16px; background-color: #ffffff;">This article originally appeared on <a href="https://theconversation.com/humans-are-still-hunting-for-aliens-heres-how-astronomers-are-looking-for-life-beyond-earth-197621" target="_blank" rel="noopener">The Conversation</a>. </em></p>

“As good as it gets”: Behind the scenes of Elton John’s final tour

<p>Richard Wilkins has shared priceless insights into the backstage experience of Sir Elton John’s final Australian tour after attending the music legend’s concert in Newcastle – and he even ran into a few more rock celebrities while meeting the man himself. </p> <p>Wilkins had the privilege of catching up with Elton in person, after Elton launched the Australian leg of the Goodbye Yellow Brick Road Farewell Tour in Newcastle, and the Today entertainment editor reported that he "absolutely delivered in spades".</p> <p>"To witness Elton John in concert is to witness an absolute masterclass in stadium entertainment and rock and roll - witnessing a legend at the top of his game," said Wilkins on the Today segment.</p> <p>And Wilkins wasn't alone backstage when it came to rubbing shoulders with the rock and roll royalty;

5 ways to save space at home

<p>Although many of us enjoy a good de-cluttering, a more pressing problem can be finding somewhere to put the items that you decide to keep.</p> <p>Many homes lack the space for things that use to come standard such as linen cupboards and storage cupboards. In a lot of homes, built in wardrobes are seen as an optional extra rather than a must-have. Which means a lot of your treasure doesn’t have a permanent place to reside.</p> <p>Try some of our space saving ideas today, which can help you tidy away the bits and pieces that need a home.</p> <p><strong>Utilise space under the bed</strong></p> <p>Instead of letting dust set up house under there, invest in some plastic tubs that fit under your bed. Fill them with anything from sheets and blankets to shoes and hats.</p> <p><strong>Install a low bookshelf underneath windows</strong></p> <p>The area under a window is often wasted space. A small bookshelf there can hold books, games, photo albums, or even a stereo. Visit a home hardware store and look for DIY shelves.</p> <p><strong>Make your bathroom mirror into a cupboard</strong></p> <p>If you just have a standard mirror fitted, you could be missing out on a great spot to store your toiletries. A bathroom cabinet is not too expensive and means your basin is free of clutter.</p> <p><strong>Use space saver bags to store off-season clothes</strong></p> <p>These nifty little bags shrink clothes right down simply by using a vacuum cleaner to remove the air that takes up valuable space. Available from most discount stores, you can also use them for things like doonas and blankets that can take up lots of room in your linen cupboard.</p> <p><strong>Add a shelf above doorways</strong></p> <p>Another underutilised spot, the area above doors (especially hallways) is perfect for storing things like books or CDs. Check first that the wall is able to support a shelf before you start drilling.</p> <p><em>Image: Getty Images</em></p>

Banksy: who should foot the bill to protect his work in public spaces?

<p>When a mural by artist Banksy <a href="https://www.bbc.co.uk/news/uk-wales-46617742">appeared on a garage wall</a> in Port Talbot, the building’s owner, Ian Lewis, had no idea just <a href="https://www.bbc.co.uk/news/uk-wales-46771722">how many people</a> would want to get a good look at it. The mural has attracted <a href="https://www.bbc.co.uk/news/uk-wales-46759349">thousands of visitors</a> and Lewis has been keen to <a href="https://www.bbc.co.uk/news/uk-wales-46617742">protect it</a>, by employing guards, and building a see-through covering over the work.</p> <p>But should there even be security on a piece of graffiti? After all, <a href="https://hyperallergic.com/38778/occupying-the-walls-graffiti-as-political-protest/">the essence of graffiti</a> is that it is temporary and subject to the possibility of being covered over with the next slogan or image. It has long been one of the means by which people can <a href="https://www.theguardian.com/cities/gallery/2017/may/17/writing-wall-political-graffiti-banksy-brexit-trump-in-pictures">make their views known</a> in a very public way without official sanction. It is a form of protest that visually takes up public space and asks for no endorsement and often no individual credit.</p> <p>The list of graffiti artists who have gained recognition in the contemporary art world is not a long one. Shepherd Fairey, who <a href="https://www.artic.edu/artworks/229396/barack-obama-hope-poster">designed the Obama “Hope” poster</a>, and <a href="https://www.theartstory.org/artist-basquiat-jean-michel.htm">Jean Michel Basquiat</a> are two of the most well known. Banksy himself has been quoted as saying that he never craved commercial success and that it’s actually <a href="https://www.villagevoice.com/2013/10/09/village-voice-exclusive-an-interview-with-banksy-street-art-cult-hero-international-man-of-mystery/">a mark of failure for a graffiti artist</a>. </p> <p>A lofty sentiment, but whether he wants it or not, the popularity of Banksy’s work is phenomenal. The pared down stencil style coupled with often highly astute political commentary and visual puns is easy to read. It is enough to satisfy even those for whom art should consist of a “proper picture of something”.</p> <p>It also lends itself very well to reproduction and copying. I actually have a mug emblazoned with Banksy style rats sitting on my desk as I write. This is what happens when an iconoclast becomes an icon. What started out as a practice that deliberately subverted the concept of art as an exclusive, costly investment, has now become just as commodified as the latest piece by <a href="https://www.theartstory.org/artist-hirst-damien.htm">Damien Hirst</a>.</p> <h2>Banksy’s bankability</h2> <p>I’m personally on the fence about some of Banksy’s more recent work. I’m completely on board with the political nature of the imagery and most definitely share a lot of his ideological sentiments, but there is a degree to which he is becoming a parody of himself. For example, while it’s easy to appreciate the point he was making with the recently auctioned self-destructing drawing “<a href="https://theconversation.com/banksy-i-was-in-the-room-when-his-painting-shredded-and-enhanced-his-brand-104660">Love is in the Bin</a>”, no one could convince me that he was unaware of the effect that the action would have on his bankability.</p> <p>Given he knows the impact his work can have, was it selfish of Banksy to impose this latest piece on the unsuspecting garage owner? Or was it an act of extreme philanthropy, bestowing on Port Talbot a gift that can be used either to benefit the individual or the community? He must have known that Lewis would be plagued with attention, and the inevitability of this imposed cultural responsibility must surely have at least crossed Banksy’s mind. </p> <p>Public art comes in many diverse forms, from the monumental statues commemorating historical figures, to the temporary and often illegal murals created by contemporary graffiti artists. My own practice is informed by an ethos of inclusion that places the nearby community at the centre of decisions about how it is created, themed and managed.</p> <p>Because of that philosophical background, I do find Banksy’s imposition of his work without regard for its effect on the local community to be irritatingly entitled. However, the <a href="https://www.theartstory.org/artist-banksy-artworks.htm">issues he highlights</a> such as the <a href="https://theartstack.com/artist/banksy/i-remember-when-all-this-was-trees">capitalist obsession with growth</a> over sustainability, and <a href="https://www.independent.co.uk/voices/banksy-port-talbot-graffiti-wales-michael-sheen-steel-pollution-environment-a8692821.html">industrial air pollution</a> are relevant and important to a much wider community, so I appreciate that by using his fame to draw attention to them he is carrying out a form of community service.</p> <p>The Welsh government <a href="https://www.walesonline.co.uk/news/wales-news/banksy-collector-willing-pay-six-15656998">has since confirmed</a> it will be taking over security for the Port Talbot artwork, and is discussing the future of the piece. Whether by design or because he just isn’t interested in how the work is used, it’s part of Banksy’s artistic practice to leave the work to the mercy of others when it’s complete. However, it could be argued that he could have used <a href="https://www.artspace.com/magazine/art_101/close_look/how-does-banksy-make-money-or-a-lesson-in-art-market-economics-55352">some of his own money</a> to help protect the work, and mitigate against any grief <a href="https://www.bbc.co.uk/news/uk-wales-46810787">he’s caused the garage owner</a>.</p> <p>I’d personally like to see the work sold, and the proceeds used to address some of the social and political issues that Banksy highlights with his work. It worked for Dennis Stinchcombe who, when a mural entitled Mobile Lovers appeared on the doorway of his Bristol youth club in 2014, sold the work and used the funds <a href="https://www.bbc.co.uk/news/uk-wales-46810787">to save the struggling organisation</a>. </p> <p>Whatever happens now, one thing is certain: Banksy certainly knows how to get his work in the news.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/banksy-who-should-foot-the-bill-to-protect-his-work-in-public-spaces-109831" target="_blank" rel="noopener">The Conversation</a>. </em></p>

The world finally has its first ‘parastronaut’

<p>The European Space Agency made history last week with the announcement of the first “parastronaut”, 41-year-old UK citizen John McFall.</p> <p>He is the first candidate selected for the Parastronaut Feasibility project, <a href="https://www.esa.int/About_Us/Careers_at_ESA/ESA_Astronaut_Selection/Parastronaut_feasibility_project" target="_blank" rel="noopener">described by ESA as</a> a “serious, dedicated and honest attempt to clear the path to space for a professional astronaut with a physical disability”.</p> <p>McFall, a former Paralympic sprinter, had his right leg amputated after a motorcycle accident at age 19.</p> <p>Most of us are familiar with images of gruelling astronaut selection tests and training from movies such as The Right Stuff. ESA seeks to answer the practical question of what changes to training and equipment need to be made for a physically disabled person to travel to space.</p> <h2>How are astronauts selected?</h2> <p>NASA first selected astronauts, <a href="https://www.life.com/history/mercury-seven-photos-of-nasa-astronauts-in-training/" target="_blank" rel="noopener">the Mercury Seven</a>, in 1959. Recruitment was limited to male military test pilots less than 40 years old, in excellent physical and mental health, and less than 1.8m tall (the Mercury capsule was tiny).</p> <p>Today, NASA uses a similar basic eligibility screening. Applicants must have 20/20 vision (corrective lenses and laser eye surgery are okay) with blood pressure under 140/90 when seated and a height between 1.49 and 1.93m (to fit <a href="https://theconversation.com/what-does-it-take-to-do-a-spacewalk-skill-courage-and-being-able-to-wear-a-mens-size-medium-163256" target="_blank" rel="noopener">available spacesuits</a>).</p> <p>However, this is the easy part. Candidates endure several rounds of interviews and testing, and if lucky enough to be selected will need to pass the long-duration flight astronaut physical. It’s a gruelling week-long test of physical abilities necessary for space, such as agility and hand-eye coordination, as well as tolerance of extreme pressure and inertial (rotating) environments.</p> <p>This is followed by a two-year training period mastering complex space hardware and software, performing simulated EVAs (spacewalks) in Houston’s <a href="https://www.nasa.gov/centers/johnson/pdf/167748main_FS_NBL508c.pdf" target="_blank" rel="noopener">Neutral Buoyancy Laboratory</a>, and experiencing weightlessness during <a href="https://www.nasa.gov/analogs/parabolic-flight" target="_blank" rel="noopener">parabolic flight</a>.</p> <p>Although I have described the NASA process here, similar programs are used across space agencies. Determining what adaptations to training are required to allow participation by physically disabled candidates will be one outcome of the parastronaut project.</p> <h2>Astronaut diversity is improving</h2> <p>Culturally, astronaut selection criteria have slowly evolved since the first all-male, all-military cohorts. The first female (and civilian) in space, Soviet cosmonaut <a href="https://starchild.gsfc.nasa.gov/docs/StarChild/whos_who_level2/tereshkova.html" target="_blank" rel="noopener">Valentina Tereshkova</a>, flew on the Vostok 6 capsule in 1963.</p> <p>It was another 15 years before NASA selected female astronauts, and a further five before <a href="https://www.nasa.gov/feature/sally-ride-first-american-woman-in-space/" target="_blank" rel="noopener">Sally Ride</a> became the first US woman in space aboard the shuttle Challenger in 1983. The first NASA astronaut of colour, <a href="https://www.nasa.gov/subject/11054/guy-bluford/" target="_blank" rel="noopener">Guion “Guy” Bluford</a>, flew in the same year.</p> <p>The 2021 NASA astronaut class of ten candidates, <a href="https://www.nasa.gov/press-release/nasa-selects-new-astronaut-recruits-to-train-for-future-missions" target="_blank" rel="noopener">Group 23</a>, included four women and several candidates from culturally diverse backgrounds.</p> <p>It would appear that diversity in astronaut selection has lagged behind society, and ESA has made a bold step with the parastronaut project.</p> <h2>Levelling the playing field</h2> <p>ESA has initially focused on candidates with a lower-limb disability. Astronauts primarily use their upper body to get around in weightlessness, and a lower-limb disability is unlikely to impair movement. In this respect, zero-g presents a level playing field.</p> <p>Issues are likely to arise when operating existing space hardware. The parastronaut study aims to determine what modifications to launch vehicles, spacesuits and other space systems would be necessary to allow a physically disabled astronaut to live and work in space.</p> <p>There is precedent for an astronaut with a progressively disabling condition flying in space. NASA astronaut <a href="https://spacecenter.org/remembering-nasa-astronaut-rich-clifford/" target="_blank" rel="noopener">Rich Clifford</a> was diagnosed with Parkinson’s disease in 1994 after noticing a lack of movement in his right arm when walking, shortly before his third scheduled shuttle flight.</p> <p>NASA not only allowed him to launch aboard Atlantis in 1996 for his final mission, but scheduled Clifford for a six-hour EVA on the exterior of the Mir space station.</p> <p>Although his experience was largely positive, Clifford did note he had difficulty donning his spacesuit due to limited motion of his right arm. The human-machine interface may present the biggest challenge for future parastronauts.</p> <h2>Space is still risky and extreme</h2> <p>In November 2021 we passed the milestone of <a href="https://www.npr.org/2021/11/10/1054575533/spacex-launch" target="_blank" rel="noopener">600 humans having gone to space</a>. Compare that to the 674 million passengers who flew on US airlines in 2021 alone.</p> <p>If we could travel back in time to when only 600 people had flown in aeroplanes, we would find the risk of flying considerably higher than today. This is where we are with spaceflight.</p> <p>It remains a high-risk venture to an extreme environment with significant physical and mental challenges. We are still a long way from anyone being able to travel to space, although hopefully we won’t have to wait until billions of people have launched to reach a level of safety comparable to modern commercial aviation.</p> <p>Our knowledge of the physical, mental and operational risks associated with spaceflight is still incomplete. Of the 600+ space travellers to date, only 70 have been female, and an understanding of gender difference in space health is only just beginning to emerge.</p> <p>How would a physical disability affect an astronaut’s performance in space? We don’t know, but ESA is taking the first step in finding out. It would appear that space truly is the last frontier.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/the-world-finally-has-its-first-parastronaut-can-we-expect-anyone-to-be-able-to-go-to-space-one-day-195566" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: ESA</em></p>

Caught in the act: supermassive black hole 8.5 billion light years away enjoys violent stellar snack

<p>A supermassive black hole at the centre of a galaxy some 8.5 billion years way has ripped apart a nearby star, producing some of the most luminous jets ever seen.</p> <p>When stars and other objects stray too close to a <a href="https://cosmosmagazine.com/space/how-big-is-a-black-hole-watch-how-it-eats/" target="_blank" rel="noreferrer noopener">supermassive black hole</a> they are destroyed by the black hole’s immense gravity.</p> <p>These occurrences, known as <a href="https://cosmosmagazine.com/space/a-star-is-torn/" target="_blank" rel="noreferrer noopener">tidal-disruption events (TDEs)</a>, result in a <a href="https://cosmosmagazine.com/space/the-sleeping-giant-black-hole-that-awoke-to-destroy-a-star/" target="_blank" rel="noreferrer noopener">circling disk of material</a> that is slowly pulled into the black hole and very occasionally, as in the case of supermassive black hole AT2022cmc, ejecting bright beams of material travelling close to the speed of light.</p> <p>Luminous jets are produced in an estimated 1% of cases and are known as a type of astronomical occurrence known as a transient, because they are short-lived.</p> <p>Bright flashes from the jets were spotted in data from the <a href="https://www.ztf.caltech.edu/" target="_blank" rel="noreferrer noopener">Zwicky Transient Facility (ZTF)</a> in <a href="https://astronomerstelegram.org/?read=15232" target="_blank" rel="noreferrer noopener">February this year</a> using a special new technique which can comb through the equivalent of a million pages of information every night.</p> <p>Due to the rapid results produced by the novel data analysis method, a research team in the US was able to swiftly follow up on the transient event with multiwavelength observations of the system from different observatory facilities.</p> <p>The jets were visible across many wavelengths, from X-rays to radio, and follow-up observations enabled the European Southern Observatory’s <a href="https://www.eso.org/public/australia/teles-instr/paranal-observatory/vlt/" target="_blank" rel="noreferrer noopener">Very Large Telescope</a> to place AT2022cmc at a whopping distance of 8.5 billion light years away, while optical and infrared observation from NASA’s <a href="https://www.nasa.gov/mission_pages/hubble/main/index.html" target="_blank" rel="noreferrer noopener">Hubble telescope</a> were able to precisely pinpoint AT2022cmc’s location.</p> <p>“The last time scientists discovered one of these jets was well over a decade ago,” said Michael Coughlin, an assistant professor of astronomy at the University of Minnesota Twin Cities and co-lead on the paper <a href="https://www.doi.org/10.1038/s41586-022-05465-8" target="_blank" rel="noreferrer noopener">published in <em>Nature</em></a>. “From the data we have, we can estimate that relativistic jets are launched in only 1% of these destructive events, making AT2022cmc an extremely rare occurrence.”</p> <p>Exactly why this behaviour is so rare remains an enigma, however, the research team believe that AT2022cmc’s rapid spin powers the jets, adding to the current understanding of the physics of these behemoth dead stars at the centres of galaxies.</p> <p>This detection – and the method used to discover it – are valuable as a future models for astronomers as they scour the skies for more events. “Scientists can use AT2022cmc as a model for what to look for and find more disruptive events from distant black holes,” says lead author Igor Andreoni, from the Department of Astronomy at UMD and NASA Goddard Space Flight Centre.</p> <p>This includes using ground-based optical surveys, as opposed to gamma-ray observatories in space – how previous jets were primarily discovered.</p> <p>“Our new search technique helps us to quickly identify rare cosmic events in the ZTF survey data,” says Andreoni.</p> <p>“And since ZTF and upcoming larger surveys such as <a href="https://www.lsst.org/" target="_blank" rel="noreferrer noopener">Vera Rubin’s Large Synoptic Survey Telescope</a> scan the sky so frequently, we can now expect to uncover a wealth of rare, or previously undiscovered cosmic events and study them in detail.

When hosting mega-events like FIFA, cities market themselves at the expense of the most vulnerable

<p>Few events capture the attention of the globe like the Men’s FIFA World Cup — in 2018, the event boasted a viewership of <a href="https://www.fifa.com/tournaments/mens/worldcup/2018russia/media-releases/more-than-half-the-world-watched-record-breaking-2018-world-cup">3.5 billion people</a>. Yet, despite the enormous popularity of the World Cup, <a href="https://www.aljazeera.com/sports/2022/11/17/do-host-countries-make-money-from-the-world-cup">host cities and countries invariably lose money</a> on the event itself, with FIFA capturing most of the profits despite its non-profit status.</p> <p>The calculus of host cities is based on the hope that successfully hosting a World Cup (or Olympics) will significantly enhance a city’s urban brand and ultimately lead to long-term increases in tourism and foreign direct investment.</p> <p>In other words, the argument is that a successful stint as a host city will identify that city as “<a href="https://www.jstor.org/stable/40643231">world-class</a>” and change its economic fortunes. This justification, at least from an economic point of view, relies on <a href="https://doi.org/10.1080/02614360500504628">some pretty fuzzy math and long-term forecasting that rarely gets audited</a>.</p> <p>I attended the 2010 World Cup in South Africa to study how various communities attempted to have their voices heard and needs met through the planning process for that event. I continue to research how hosting large-scale events intersect with other trends in global and local urbanization.</p> <p><strong>Urban branding</strong></p> <p>This mission of improving one’s urban brand to attract tourist and foreign investment leads cities to focus their attention to the perceived needs. Or, more precisely, the perceived desires of potential tourists and investors, as opposed to the needs and desires of the people who already live, work and play in these cities.</p> <p>This shift in focus is part of larger trends of cities becoming <a href="https://doi.org/10.1080/04353684.1989.11879583">increasingly entrepreneurial in our globalized world</a>.</p> <p>And to this end, host cities pursue a fairly predictable path to demonstrate their world-classness. As Streetnet International, a South Africa-based international organization of street vendors, put it in their World Class Cities For All campaign:</p> <blockquote> <p>“It has become a boringly predictable reality that, when a country prepares to host a high-profile international event, <a href="https://streetnet.org.za/document/world-class-cities-for-all/">the country and its local government authorities prepare to create ‘World Class Cities’ of a particular type</a>, i.e. ‘World Class Cities’ which will attract foreign investment; have modern up-to-date infrastructure; have no visible signs of urban decay; have smooth traffic flows; have no visible poor people or social problems.”</p> </blockquote> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/497721/original/file-20221128-4871-ip7vgt.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/497721/original/file-20221128-4871-ip7vgt.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/497721/original/file-20221128-4871-ip7vgt.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=402&fit=crop&dpr=1 600w, https://images.theconversation.com/files/497721/original/file-20221128-4871-ip7vgt.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=402&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/497721/original/file-20221128-4871-ip7vgt.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=402&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/497721/original/file-20221128-4871-ip7vgt.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=506&fit=crop&dpr=1 754w, https://images.theconversation.com/files/497721/original/file-20221128-4871-ip7vgt.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=506&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/497721/original/file-20221128-4871-ip7vgt.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=506&fit=crop&dpr=3 2262w" alt="overhead view of a building site in the desert" /></a><figcaption><span class="caption">In Doha, several stadiums were built to host the FIFA World Cup.</span> <span class="attribution"><span class="source">(AP Photo/Vadim Ghirda)</span></span></figcaption></figure> <p><strong>Increased policing, decreased social investment</strong></p> <p>There are common themes to how cities approach their hosting duties and branding pursuits.

How satellites, radar and drones are tracking meteorites and aiding Earth’s asteroid defence

<p>On July 31 2013 a <a href="https://cneos.jpl.nasa.gov/fireballs/" target="_blank" rel="noopener">constellation of US defence satellites</a> saw a streak of light over South Australia as a rock from outer space burned through Earth’s atmosphere on its way to crash into the ground below.</p> <p>The impact created an explosion equivalent to about 220 tonnes of TNT. More than 1,500km away, in Tasmania, the bang was heard by detectors normally used to listen for <a href="https://www.dfat.gov.au/international-relations/security/asno/Pages/australian-ims-stations" target="_blank" rel="noopener">extremely low-frequency sounds</a> from illegal tests of nuclear weapons.</p> <p>These were two excellent indications that there should be a patch of ground covered in meteorites somewhere north of Port Augusta. But how could we track them down?</p> <p>My colleagues and I who work on the <a href="https://dfn.gfo.rocks/" target="_blank" rel="noopener">Desert Fireball Network (DFN)</a>, which tracks incoming asteroids and <a href="https://dfn.gfo.rocks/meteorites.html" target="_blank" rel="noopener">the resulting meteorites</a>, had a couple of ideas: weather radar and drones.</p> <p><strong>Eyes in space</strong></p> <p>Finding meteorites is not an easy task. There is a network of high-quality ground-based sensors called the <a href="https://gfo.rocks/" target="_blank" rel="noopener">Global Fireball Observatory</a>, but it only covers about 1% of the planet.</p> <p>The <a href="https://cneos.jpl.nasa.gov/fireballs/" target="_blank" rel="noopener">US satellite data</a> published by NASA covers a much larger area than ground-based detectors, but it only picks up the biggest fireballs. What’s more, they <a href="https://academic.oup.com/mnras/article/483/4/5166/5256650" target="_blank" rel="noopener">don’t always give an accurate idea of the meteor’s trajectory</a>.</p> <p>So, to have any chance to find a meteorite from these data, you need a little outside help.</p> <p><strong>Weather radars</strong></p> <p>In 2019, Australia’s Bureau of Meteorology started making its weather radar data <a href="https://www.openradar.io/" target="_blank" rel="noopener">openly available</a> to researchers and the public. I saw this as an opportunity to complete the puzzle.</p> <p>I combed through the record of events from the Desert Fireball Network and NASA, and cross-matched them with nearby weather radars. Then I looked for unusual radar signatures that could indicate the presence of falling meteorites.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=334&fit=crop&dpr=1 600w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=334&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=334&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=420&fit=crop&dpr=1 754w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=420&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=420&fit=crop&dpr=3 2262w" alt="An annoyed aerial photo showing the locations of the Woomera radar station and the falling meteorites." /></a><figcaption><span class="caption">The Woomera weather radar station captured reflections from the falling meteorites.</span> <span class="attribution"><span class="source">Curtin University</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>And bingo, the 2013 event was not too far from the Woomera radar station. The weather was clear, and the radar record showed some small reflections at about the right place and time.</p> <p>Next, I had to use the weather data to figure out how the wind would have pushed the meteorites around on their way down to Earth.</p> <p>If I got the calculations right, I would have a treasure map showing the location of a rich haul of meteorites. If I got them wrong, I would end up sending my team to wander around in the desert for two weeks for nothing.</p> <p><strong>The search</strong></p> <p>I gave what I hoped was an accurate treasure map to my colleague Andy Tomkins from Monash University. In September this year, he happened to be driving past the site on his way back from an expedition in the Nullarbor.</p> <p>Thankfully, Andy found the first meteorite within 10 minutes of looking. In the following two hours, his team found nine more.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Photo of several people walking through a desert field looking at the ground." /><figcaption><span class="caption">A field team from Monash University searched for meteorites in the strewn field.</span> <span class="attribution"><span class="source">Monash University</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>The technique of finding meteorites with weather radars <a href="https://ares.jsc.nasa.gov/meteorite-falls/how-to-find-meteorites/" target="_blank" rel="noopener">was pioneered</a> by my colleague Marc Fries in the US.

For example, the 17-metre asteroid that exploded over Chelyabinsk in Russia in 2013 produced an explosion 30 times the size of the bomb dropped on Hiroshima in 1945.</p> <p>So when the next big one is about to hit, it may be useful to predict how it will deposit its energy in our atmosphere.</p> <p>With new telescopes and better technology, we are starting to see some asteroids <a href="https://skymapper.anu.edu.au/news/great-balls-fire/" target="_blank" rel="noopener">before they hit Earth</a>. We will see even more when projects such as the <a href="https://www.lsst.org" target="_blank" rel="noopener">Vera Rubin Observatory</a> and the <a href="https://atlas.fallingstar.com" target="_blank" rel="noopener">Asteroid Terrestrial-impact Last Alert System (ATLAS)</a> are up and running.</p> <p>These systems might give us as much as a few days’ notice that an asteroid is heading for Earth. This would be too late to make any effort to deflect it – but plenty of time for preparation and damage control on the ground.</p> <p><strong>The value of open data</strong></p> <p>This find was only made possible by the free availability of crucial data – and the people who made it available.</p> <p>The US satellites that detected the fireball are presumably there to detect missile and rocket launches. However, somebody (I don’t know who) must have figured out how to publish some of the satellite data without giving away too much about their capabilities, and then lobbied hard to get the data released.</p> <p>Likewise, the find would not have happened without the work of Joshua Soderholm at Australia’s Bureau of Meteorology, who worked to make low-level weather radar data openly accessible for other uses. Soderholm went to the trouble to make the radar data <a href="https://www.go-fair.org/fair-principles/" target="_blank" rel="noopener">readily available and easy to use</a>, which goes well beyond the vague formulations you can read at the bottom of scientific papers like “data available upon reasonable request”.</p> <p>There is no shortage of fireballs to track down.
