How would a piano sound on Mars? Embark on an interplanetary sonic journey – Aeon Videos If the Universe is born and no one is present to hear it, does it still make a sound? Well, theoretically, yes. As this video from the US filmmaker John D Boswell explores, where a ‘thick soup of atoms’ is present, sound is possible. Made in collaboration with the podcast Twenty Thousand Hertz, this short documentary deploys dramatic CGI visuals, a pulsing score and the voices of prominent scientists to explore the sounds of space – from those humanity has recorded to those we can only speculate about.
The Sounds of Space: A sonic adventure to other worlds – YouTube Space is more than just a feast for the eyes. It’s a feast for the ears. You just have to know where — and when — to look. Floating in the silent void of space are trillions of islands of sound, each with their own sonic flavor — some eerily familiar, some wildly different than Earth’s. And even space itself was once brimming with sound.
Hosts of Australia’s Today giggle their way through a segment on Jeff Bezos’ weiner-shaped spacecraft – AV Club Last week, we learned that Dr. Evil cosplayer Jeff Bezos would be leaving for space on a rocket that completes his attempts to fully embody the Austin Powers villain by being shaped like a giant metal penis. The hosts of Australia’s Today morning show were tasked with reporting on this story when it was first announced, and found themselves giggling through the entire segment as images of space dicks were displayed on the green screen behind them.
Woodsat is the brainchild of Jari Makinen, co-founder of CubeSat replica kit company Arctic Astronautics. The European Space Agency, or ESA, is providing a suite of sensors to track the satellite’s performance and will also help with pre-flight testing.
I remember reading about something similar last year.
Japan developing wooden satellites to cut space junk – BBC News A Japanese company and Kyoto University have joined forces to develop what they hope will be the world’s first satellites made out of wood by 2023. … Space junk is becoming an increasing problem as more satellites are launched into the atmosphere. Wooden satellites would burn up without releasing harmful substances into the atmosphere or raining debris on the ground when they plunge back to Earth.
Coverage of “wooden satellites” misses the point – Ars Technica Unfortunately, making satellite housings out of wood won’t help with this, for many, many reasons. To start with, a lot of the junk isn’t ex-satellites; it’s often the boosters and other hardware that got them to orbit in the first place. Housings are also only a fraction of the material in a satellite, leaving lots of additional junk untouched by the change, and any wood that’s robust enough to function as an effective satellite housing will be extremely dangerous if it impacts anything at orbital speeds.
The experts fell short. The group determined that none of Earth’s existing technologies could stop the asteroid from striking given the six-month time frame of the simulation. In this alternate reality, the asteroid crashed into eastern Europe.
US military has ‘no plan’ to shoot down debris from falling Chinese rocket – The Guardian Speaking with reporters, the US defence secretary, Lloyd Austin, said the hope was the rocket would land in the ocean and that the latest estimate was that it would come down between Saturday and Sunday. … The Global Times, a Chinese tabloid published by the official People’s Daily, characterized reports that the rocket is “out of control” and could cause damage as “Western hype”. The situation is “not worth panicking about”, it said, citing industry insiders.
Let’s hope those things whizzing above our heads are just satellites and nothing scarier.
For more UFO debunking, you must check out Metabunk.
Cigar shaped UFO over Angels Landing, Utah [Probably Starlink] – Metabunk That doesn’t look like a plane to me at all but I’m pretty certain that you got video of the initial satellite train of the Starlink 22 deployment. A Falcon 9 had launched from Cape Canaveral about three hours earlier. The sats are still clustered together fairly closely since they had only recently been released.
Utah Drone video of UFO [Probably an insect] – Metabunk A few days ago, a youtube video was posted on Reddit r/UFO’s showing an object flying by a drone … With these clear videos is I think we could do some calculations, or other advanced analysis? I am tending towards cgi myself. … Here’s an animation I quickly did of a bug sized object (1cm across) moving at a bug like speed (about 7km/h) towards an approaching camera moving at drone like speed (30km/h). For the FOV I used that of the DJI Phantom Pro 4, the forward camera of which is listed as 50 degrees.
Mick West, the man behind Metabunk, is incredibly thorough in his work, as can be seen by this thread investigating UFOs over Loch Ness. But perhaps there are some satellites overhead right now?
But even on a clear night you might have a problem with light pollution.
Light pollution map A mapping application that displays light pollution related content over Microsoft Bing base layers (road and hybrid Bing maps). The primary use was to show VIIRS/DMSP data in a friendly manner, but over the many years it received also some other interesting light pollution related content like SQM/SQC measurements, World Atlas 2015 zenith brigtness, almost realtime clouds , aurora prediction and IAU observatories features.
England’s quite bright everywhere, especially where I live, though I can see just how well positioned the Kielder Observatory is now. And I’m guessing those islands in the North Sea are oil rigs? Look how so well defined Belgium’s borders are, much like the line between North and South Korea further round the globe.
Reminds me of when I tried looking for Street Views across Europe once. Are there no streets in Germany?
I’m sure President Biden has enough on his to-do list at the moment to be giving Space Force and the politics of space much thought, but this new book from Benedict Redgrove might spark some enthusiasm.
Benedict Redgrove’s intimate photography book lands us inside the world of NASA – IGNANT Redgrove has been fascinated by space suits and shuttles since he was a young man. “The image of the astronaut or spaceman has been with me ever since, as a sort of talisman to all that is great and good,” he shares. “They symbolize the explorer, the hero, the good character, the leader. The spacesuit takes on that character, the suit and the human become one entity, more powerful than either on their own.” Combining his fascination with space technology with his interest in photography, the British creative took on the challenge to document America’s home of space-based research and development in intimate detail. Redgrove spent almost a decade working on the project, negotiating access and forming relationships with NASA, researching, investigating, and producing over 200 images of NASA’s facilities and the many objects that made their space travel imaginable and possible.
The engineering involved in landing on the moon was incredible. To fully appreciate that, I think I need to add this epic piece of journalism to my reading list.
Of a Fire on the Moon by Norman Mailer – Penguin Random House For many, the moon landing was the defining event of the twentieth century. So it seems only fitting that Norman Mailer—the literary provocateur who altered the landscape of American nonfiction—wrote the most wide-ranging, far-seeing chronicle of the Apollo 11 mission. A classic chronicle of America’s reach for greatness in the midst of the Cold War, Of a Fire on the Moon compiles the reportage Mailer published between 1969 and 1970 in Life magazine: gripping firsthand dispatches from inside NASA’s clandestine operations in Houston and Cape Kennedy; technical insights into the magnitude of their awe-inspiring feat; and prescient meditations that place the event in human context as only Mailer could.
That line about the poor quality visuals (deliberately poor, apparently) not matching the scale of the achievement reminded me of Brian Eno’s dissatisfaction with the audio, the chatter of the experts obscuring the event’s grandeur and strangeness.
Of a Fire on the Moon was first published across three issues of Life magazine (much like John Hersey’s Hiroshima, published in its entirety in The New Yorker in 1946), and is yours in book form for a tenner or so. Or, if you want to spend a little more…
Of a Fire on the Moon; $112,500 coffee table edition – Wikipedia The 40th anniversary of the first Moon landing was marked in 2009 by the release of an abridged, limited edition of the text, re-packaged with images from NASA and Life magazine. This production retitled the work, MoonFire, and was presented in an aluminium box with a lid shaped like the crater-pocked surface of the Moon; the object was mounted on four legs resembling the Apollo Lunar Module’s struts. Thus, the coffee table book came inside its own lunar-themed “coffee table”, with an uneven surface (see photograph). The package included a numbered print of the famous portrait of Buzz Aldrin standing on the Moon, framed in plexiglass and signed by the astronaut himself—and enclosed a lunar meteorite. Only 12 were created and the price was $112,500.
NASA’s ‘worm’ logo lay dormant for 28 years. So why are people so obsessed with it? – Fast Company Danne says these simple, elegant, and versatile visual elements also underscore a deeper meaning. “NASA is very romantic and sexy,” he says. Especially when compared to other government agencies, like the Department of Transportation. “They both have motion built into their matrix, but NASA is the only one that has adventure and exploration.” It represents an entity that takes humans to the furthest possible realms; In just four letters, it “personifies innovation and moving ahead.”
New image captures ‘impossible’ view of the moon’s surface – Live Science McCarthy trained his camera on the craters closest to the lunar terminator every night for two weeks as the moon waxed toward complete illumination. By the time the moon was full, McCarthy had a series of high-contrast, high-definition photos of every crater on the moon’s Earth-facing side. Blending them into a single composite image was “exhausting,” he wrote, but ultimately resulted in the gorgeously detailed shot seen above — an image that McCarthy calls the “all terminator” moon.
Whenever I look at a full moon I find it hard to remember it’s spherical. It’s just a flat white circle an inch or two across that someone’s pinned up there, surely, not a solid ball of rock, the size of the United States, that’s slowly drifting away from us. This image, whilst being incredibly detailed, doesn’t help—for all its deep shadows and highlights, the lack of a ‘proper’ lunar terminator still makes it look more disk-like than globe-like, I think. (I wonder if there’s a Flat Moon Society I could join.)
If the moon is a fundamentally strange and other-worldly object, what to make of black holes? This film, like the composite photograph above, might be bending the truth, but is nevertheless equally impactful.
Nebula-75 feels so much like the show I wanted to make myself, with cardboard boxes, kitchen implements, and household junk, after watching these programs when I was a wee one. That was one of the things that made them so seductive to a young and over-active imagination — they seemed so doable. And here, lo these many years later, folks associated with the legacy of these shows are doing it. At home. With cardboard boxes and junk. I’m inspired all over again.
Thunderbirds! Captain Scarlet! They don’t make ’em like that anymore. It turns out, they do.

How Mandela stayed fit: from his ‘matchbox’ Soweto home to a prison cell – The Conversation
He’d begin with running on the spot for 45 minutes, followed by 100 fingertip push-ups, 200 sit-ups, 50 deep knee-bends and calisthenic exercises learnt from his gym training (in those days, and even today, this would include star jumps and ‘burpees’ – where you start upright, move down into a squat position, kick your feet back, return to squat and stand up). Mandela would do this Mondays to Thursdays, and then rest for three days. This continued even during his several spells in solitary confinement.
Jacob Solome survived the Holocaust by hiding in a small basement for two years with up to 15 others.
My cousin Jack survived the unimaginable. Here’s his advice for right now. – The Cut
This is my philosophy, and so far it has helped. Because I compare myself to other people who worry all the time, and always when you see them, they are telling you about their tsuris and their problems. Some people are optimistic, but some people are more pessimistic. I am in the first category. Really, that’s the nature of a person. I’m always thinking how worse it was when we were under the German occupation, where every minute, our lives were at risk; literally, being in the ghetto and being in hiding. So if I was able to live through that, what the heck is coronavirus?
And from The Economist, advice from a former hostage, a writer with chronic fatigue and an astronaut.
Stories of an extraordinary world – Notes on isolation, from those who know it well – The Economist
When I was in space, Mission Control scheduled my days to the minute. Every evening the information they sent would come out like a fax machine, a long thin bit of paper telling me exactly what time I should get up, when I should eat, what experiments I should do and when. I didn’t mind – it was efficient – but I did get comfort from the small things that I could control, like what juice I drank and the time after dinner when I really could do whatever I wanted. Now my days are restricted like everyone else – my speaking engagements have been cancelled and my work for Imperial College London is moving online – but I still take pleasure in the small things; deciding my morning run and what path I take. I remember that lesson from space, letting go of what you can’t control and focusing on what you can. We have all been told to stay at home – but we can still decide how we use our time.
As we come to terms with the latest numbers and updates about everyone’s favourite virus, we can be thankful, at least, that we don’t have this to worry about:
Wasp-76b: The exotic inferno planet where it ‘rains iron’ – BBC News
Wasp-76b, as it’s known, orbits so close in to its host star, its dayside temperatures exceed 2,400C – hot enough to vaporise metals. The planet’s nightside, on the other hand, is 1,000 degrees cooler, allowing those metals to condense and rain out. It’s a bizarre environment, according to Dr David Ehrenreich from the University of Geneva. “Imagine instead of a drizzle of water droplets, you have iron droplets splashing down,” he told BBC News.
ESO telescope observes exoplanet where it rains iron – ESO
This strange phenomenon happens because the ‘iron rain’ planet only ever shows one face, its day side, to its parent star, its cooler night side remaining in perpetual darkness. Like the Moon on its orbit around the Earth, WASP-76b is ‘tidally locked’: it takes as long to rotate around its axis as it does to go around the star.
One way of escaping our worrieshereonEarth could be to take a trip to the International Space Station. That might not work out so well, though.
Life on the Space Station is about to get really weird and lonely – Wired UK
Right now, there are six astronauts aboard the International Space Station, floating 408km above our heads. But soon things could be about to get a lot lonelier up there. Delays in building new spacecraft to get astronauts into space mean that the next trio of astronauts set to join the ISS in April 2020 are facing the possibility of being the space station’s lone occupants for six months.
Space can make your blood flow backwards – BGR
On Earth, gravity aids in draining blood from the head and ensuring a steady flow. In space, that assistance just isn’t there, and slow-moving or stagnant blood can cause clotting. In fact, two of the crew members were found to have clots or partial clots in their left internal jugular vein. Blood clotting is incredibly dangerous when it happens within the body, and if a clot were to form and then travel to the lungs it could create a pulmonary embolism, which is a potentially fatal condition that requires immediate treatment.
In keeping with the harsh aesthetic of that Black Rain video from earlier, here’s another look at what’s above us.
In 2016 an exciting mission was ended. The Rosetta spacecraft made its final manoeuvre. A controlled hard-landing on the comet Churyumov-Gerasimenko (67p). Before that Rosetta accompanied the Comet for more than 2 years. It researched valuable scientific data, brought a lander on to the comet’s surface and took a vast number of pictures.
2017 Esa released over 400,000 images from Rosetta’s comet mission. Based on these material Motion Designer Christian Stangl and Composer Wolfgang Stangl worked together to create this short film. The sequences are digitally enhanced real-footage from the probe.
NASA went to extraordinary lengths to show that what was brought back from the moon that time was safe.
NASA fed some of its precious Apollo 11 lunar samples to cockroaches
“We had to prove that we weren’t going to contaminate not only human beings, but we weren’t going to contaminate fish and birds and animals and plants and you name it,” said Charles Berry, head of medical operations during Apollo, in an oral history. “Any of the Earth’s biosphere, we had to prove we weren’t going to affect it. So we had to develop an amazing program that was carried off really for three flights’ worth. A lot of trouble.”
50 years later, those samples are still studied.
How NASA has preserved Apollo moon rocks for 50 years
“May I hold it?” I ask Krysher. No dice. I had to ask, even though Zeigler had warned me in an e-mail before I arrived: “We have pretty strict rules about people putting their (gloved) hands in the cabinets to touch samples. Basically, it’s an only-if-you-walked-on-the-moon rule.”
Keeping pristine samples away from curious fingers allowed scientists to make one of the most surprising lunar discoveries of the last 50 years: The moon is wet. Over the last decade, scientists have found hundreds of times more water in lunar samples than researchers in the Apollo era realized existed.
A visit to NASA’s moon rock central
Science News astronomy writer Lisa Grossman went behind the scenes at NASA’s pristine sample lab at Johnson Space Center in Houston this spring and saw moon rocks up close — or as close as non-astronauts can get.
Armstrong, flying manually, had to improvise. He had roughly one minute of fuel to find a safe place to land … “The tension was through the roof,” said Charlie Duke, also in Mission Control, who was the man telling Armstrong he was flying on fumes. Duke said the tension was so great at Mission Control there was dead silence. “I’d never heard Mission Control so quiet. So that tension, it was palpable. You could feel it.”
Armstrong finally spotted smooth terrain: “And we finally landed with nobody knows exactly how much fuel. Some estimates have it at 20 seconds’ [worth].”
“Houston, Tranquility Base here. The Eagle has landed.” “Roger, Tranquility. We copy you on the ground. You’ve got a bunch of guys about to turn blue. We’re breathing again. Thanks a lot.”
An absolutely incredible journey. The risks were staggering. It could have all gone very differently.
50 facts about the Apollo 11 moon landing for its 50th anniversary 5. Richard Nixon had a speech prepared in case the Apollo 11 astronauts never came home. As with many historic undertakings, President Nixon had to prepare for the possibility that a tragedy might occur during the Apollo 11 mission. So his speechwriter, William Safire, wrote two different speeches: one to celebrate the mission’s victory, another titled “In the Event of Moon Disaster.” It stated:
“Fate has ordained that the men who went to the Moon to explore in peace will stay on the Moon to rest in peace. These brave men, Neil Armstrong and Edwin Aldrin, know that there is no hope for their recovery. But they also know that there is hope for mankind in their sacrifice.”
Thankfully, the mission was a success, though some thought the soundtrack could be improved.
Brian Eno’s soundtrack for the Apollo 11 moon landing In the months that followed, the same few seconds of Neil Armstrong’s small steps played on an endless loop on TV as anchors and journalists offered their analysis and patriotic platitudes as a soundtrack. The experts, he later wrote, “[obscured] the grandeur and strangeness of the event with a patina of down-to-earth chatter.”
In 01983, Eno decided to add his own soundtrack to the momentous event.
The Atlas of Moons Our solar system collectively hosts nearly 200 known moons, some of which are vibrant worlds in their own right. Take a tour of the major moons in our celestial menagerie, including those that are among the most mystifying—or scientifically intriguing—places in our local neighborhood.
Can’t resist just adding another article here, though I’ve mentioned some of these before.
The greatest photos ever? Why the moon landing shots are artistic masterpieces The legacy of Earthrise has never stopped growing – and the Earth, as seen by unmanned spacecraft, has never stopped shrinking. When Nasa’s Voyager probe reached the edge of the solar system it turned to take a picture of a tiny Earth alongside its neighbouring planets. The Hubble telescope and its like have shown us a sublime, colourful universe whose light-filled dust clouds are light years across.
Yet the photographs taken by the Apollo 11 astronauts and the handful of humans who followed them remain unique. They are still the only portraits of our species on another world.
I didn’t realise you could see Buzz Aldrin’s face in that photo.
The sublime Romanticism of the moon landing Virtually alone among contemporary observers in seeing the true significance of the lunar landing was Vladimir Nabokov, who rented a television set for the occasion. Asked by The New York Times for his reaction, the author of Pale Fire wrote of:
…[T]hat gentle little minuet that despite their awkward suits the two men danced with such grace to the tune of lunar gravity was a lovely sight. It was also a moment when a flag means to one more than a flag usually does. I am puzzled and pained by the fact that the English weeklies ignored the absolutely overwhelming excitement of the adventure, the strange sensual exhilaration of palpating those precious pebbles, of seeing our marbled globe in the black sky, of feeling along one’s spine the shiver and wonder of it. After all, Englishmen should understand that thrill, they who have been the greatest, the purest explorers. Why then drag in such irrelevant matters as wasted dollars and power politics?
We’re all fascinated by images of space (and from space), but their polish and stillness can sometimes hide the fuller picture.
Celebrating the rough, the raw and the human in hardcore space science
Images of space and the solar system have a powerful appeal, and amaze with their vibrant otherworldly vistas. But it’s easy to forget just how processed they are: the colours are often added for effect, and digital editing makes these pictures pop. So it’s worth remembering the human process behind space as we know it. This is precisely the aim of Black Rain, which transforms raw scientific data into pulsating audiovisual art. … Ruth Jarman and Joe Gerhardt – aka Semiconductor, the UK artist duo behind the video – say the images are a reminder of ‘the human observer, who endeavours to extend our perceptions and knowledge through technological innovation’.
A few more videos in keeping with that grainy, black and white vibe.
The first photo of a black hole
We have the first photo of a supermassive black hole, from imagery taken two years ago of the elliptical galaxy M87 (in the constellation Virgo) by the Event Horizon Telescope project. The EHT team is a group of 200 scientist that has been working on this project for two decades. The image was created using data captured from radio telescopes from Hawaii to the South Pole and beyond using very long baseline interferometry.
Compare that with this image from 1979 (colourised in 1989), “said to be the the first based on data rather than artistic speculation.”
Groundbreaking 1979 visualization of black hole – Boing Boing
“The final black and white “photographic” image was obtained from these patterns. However, lacking at the time of an appropriate drawing software, I had to create it by hand. Using numerical data from the computer, I drew directly on negative Canson paper with black India ink, placing dots more densely where the simulation showed more light – a rather painstaking process!”
As always with space stuff, I have a problem with scale. This helps enormously, though.
Timelapse of the future A regular time lapse of that voyage would take forever, so Boswell cleverly doubles the pace every 5 seconds, so that just after 4 minutes into the video, a trillion years passes in just a second or two. You’d think that after the Earth is devoured by the Sun about 3 minutes in, things would get a bit boring and you could stop watching, but then you’d miss zombie white dwarfs roaming the universe in the degenerate era, the black hole mergers era 1000 trillion trillion trillion trillion years from now, the possible creation of baby “life boat” universes, and the point at which “nothing happens and it keeps not happening forever”.
NASA’s record-setting Opportunity Rover mission on Mars comes to end
Designed to last just 90 Martian days and travel 1,100 yards (1,000 meters), Opportunity vastly surpassed all expectations in its endurance, scientific value and longevity. In addition to exceeding its life expectancy by 60 times, the rover traveled more than 28 miles (45 kilometers) by the time it reached its most appropriate final resting spot on Mars – Perseverance Valley.
Nasa confirms Mars rover Opportunity is dead
“We had expected that dust falling out of the air would accumulate on the solar rays and eventually choke off power,” Callas said. “What we didn’t expect was that wind would come along periodically and blow the dust off the arrays. It allowed us to survive not just the first winter, but all the winters we experienced on Mars.”
A dust storm has killed NASA’s longest-lived Mars rover
In 2005, Opportunity overcame a sand trap and the loss of one wheel to arrive at the Victoria crater, a 2,400-foot hole that it explored for two years, finding features at its bottom again shaped by ancient water. It next explored the Endeavor crater, 13 miles away, starting in 2011. Most recently it had traversed a narrow valley leading down into the larger Endurance crater.
As this video from NASA shows, the Rover had been on an incredible trek these last 15 years.
You know those Golden Records NASA sent into space in the 70s, on the Voyager spacecrafts? They contained images, music and sounds from Earth, as well as greetings in 55 languages. If any alien were to come across these disks, accessing their contents is far from straightforward.
Decoding images from the Golden Record You might think that the images were included in some printed or digital form, such as a .jpeg or .tiff. But back in 1977, there was no technology available to put images on analog disks. Voyager’s computer systems could only hold 69 kilobytes of information, barely enough for one image, let alone 115. So NASA invented a way to include image data on the LPs.
By projecting images onto a screen, recording them with a television camera, and then turning those video signals into audio waveforms, the images could be properly pressed onto the records. The reversal process — turning that image data back into images — is what any extraterrestrial (or curious human) would have to figure out how to do.
Nevermind the contents of these records, the instructions alone will have the aliens scratching their heads. If they have heads, of course.
The Economist has a very effective, scrolling infographic on the changing pattern of states and companies that are filling up our skies.
The space race is dominated by new contenders
Some 4,500 satellites circle Earth, providing communications services and navigational tools, monitoring weather, observing the universe, spying and doing more besides. Getting them there was once the business of the superpowers’ armed forces and space agencies. Now it is mostly done by companies and the governments of developing countries.
In the past decade the West’s space-launch market has become more competitive thanks to an innovative new entrant, SpaceX. But state-run programmes still lead the way in emerging markets. In 2003 China became the third country to put a person into orbit; India plans to follow suit in 2022. Both sell launch services to private clients. China did legalise private space flight in 2014, but no companies based there have yet reached orbit on their own.
But looking at this, you wonder if there’s any space left up there.
A beehive of satellites The launch of the first artificial satellite by the then Soviet Union in 1957 marked the beginning of the utilization of space for science and commercial activity. During the Cold War, space was a prime area of competition between the Soviet Union and the U.S.
In 1964 the first TV satellite was launched into a geostationary orbit to transmit the Olympic games from Tokyo. Later, Russian launch activities declined while other nations set up their own space programs. Thus, the number of objects in Earth orbit has increased steadily – by 200 per year on average.
The debris objects shown in the images are an artist’s impression based on actual density data. However, the debris objects are shown at an exaggerated size to make them visible at the scale shown.
