It was “definitely luck” that the dust devil appeared when it did, said the study’s lead author, who estimates there was just a 1-in-200 chance of capturing the audio.
Perseverance has been on Mars for almost two years now, and already recorded wind on Mars for the first time in February 2021.
This dust devil was recorded in late September 2021 (wonder why only now it’s being revealed?). The dust devil was “average size,” which is described as about 400 feet / 122 meters tall and 80 feet / 24 meters wide, traveling at 16 feet / 5 meters per second (≈ 11 mph / 18 mph).
UPDATE. NBC incorrectly reported in the above linked article that the dust devil was recorded by Perseverance. It was actually recorded by InSight, which has just fallen silent after four years of operation. Sigh. I should get science news directly from the source and not from unreliable “news” sites.
There are a lot of dust devils on Mars. A whole lot. Any settlement would have to be extremely prepared to deal with dust all the time, everywhere. If it ever got into equipment that regulated, say, breathable air inside habitats…
Falsified space research? No problem. The “apology bow” (sha zai, 謝罪) makes it all better.
There is a reason why Japan’s newest “micro” satellite spectacularly failed to do, well, anything.
The Japan version of NASA (Japan Aerospace Exploration Agency, called “JAXA” for some reason rather than “JAEA” — maybe the founder was a fan of X-Japan?) is riddled with incompetency and sycophancy.
Much like the rest of Japan’s government, one of the most corrupt of the world’s industrialized countries thanks to its strict “senpai-kohai” hierarchy where those at the top do no work and those at the bottom have no choice but to do what those at the top say – even if it’s illegal or immoral.
A new study shows that massive volcanic eruptions over an extended period of time may be responsible for changing the planet into what it is today. If there was simple life on ancient Venus, volcanism was its doom. The study also shows how powerful volcanic activity has played a role in shaping Earth’s habitability and how Earth only narrowly avoided the same fate as Venus.
Venus is hot enough to melt lead, which is why no spaceship has ever survived to land on the surface.
And, no, there is nothing alive floating around in its toxic atmosphere.
But this is a neat article. Three future missions are planned for Venus (two by NASA – VERITAS and DAVINCI – and one by ESA – EnVision, which sounds more like a song and dance competition than a scientific probe).
Half of a dilithium crystal? (It’s a new type of crystal called “Chang’esite” (after the ancient Chinese moon goddess).
I should be posting another chapter from Bringer of Light, but I don’t feel like writing that right now, what with a humongoid typhoon slowing churning its way here.
Courtesy NASA. Note that the blue, white, green, yellow, and orange colors are artificial, only added to make features revealed by infrared stand out for human eyes. You can see the planet’s rings, aurora, and two “tiny” moons (at left; they’re not really that tiny!).
“We’ve never seen Jupiter like this. It’s all quite incredible,” said planetary astronomer Imke de Pater, of the University of California, Berkeley, who helped lead the observations.
“We hadn’t really expected it to be this good, to be honest,” she added in a statement.
The above is supposed to be in “quote” format, but WP really messed up this feature when they switched to so-called “block” mode (which I can’t stand).
Anyway, the image is fairly spectacular, from the new James Webb Space Telescope which is positioned 1 million miles away from Earth (i.e., in the second LaGrange point, or L2).
First of all, stop calling it “the golden asteroid.” That’s confusing people (the headline of the article linked below even uses the phrase “gold mine.” Come on, lazy journalists.)
If 16 Psyche is worth mining, when could such operations proceed? Citigroup thinks that space mining, including from the moon and asteroids, will be a $100 billion-per-year business by 2040. Launch costs will continue to decrease and experience in operating in space will continue to expand until such a business makes economic sense.
Well, how heavy do you think the materials to make buildings and ships in outer space are?
If we’re serious about putting people on the Moon and Mars, then it makes much more sense to set up robotic mining factories and assemble everything in space.
All this needs is a little incentive…like a new space race…
Our search for alien life is getting serious. With better telescopes and a growing scientific consensus that we’re probably not alone in the universe, we’re beginning to look farther and wider across the vastness of space for evidence of extraterrestrials.
But it’s possible we’re looking for too few signs in too few places. Having evolved on Earth, surrounded by Earth life, we assume alien life would look and behave like terrestrial life.
