Japanese space company Astroscale Holdings Inc has unveiled what it calls the world’s first publicly released close-up image taken of space debris, hailing it as progress toward understanding the challenges posed by trash orbiting Earth.

Hmm.🤔 what will happen to the rocket and the satellite that took this picture?

NASA says it is once again able to get meaningful information back from the Voyager 1 probe, after months of troubleshooting a glitch that had this venerable spacecraft sending home messages that made no sense.

Hmm. Just a short while ago, Voyager’s days were numbered.
I guess these things were built to last… (also built when NASA got a lot more funding…)

There are many words that could be used to describe WASP-76b — hellish, scorching, turbulent, chaotic, and even violent. This is a planet outside the solar system that sits so close to its star it gets hot enough to vaporize lead. So, as you can imagine, until now, “glorious” wasn’t one of those words.

This planet (located in the constellation Pisces) seems to have a rainbow effect of concentric rings…despite being so hot that iron falls from the sky.

Researchers will fly rockets into the path of the eclipse, stand in zoos watching animals, send radio signals across the globe, and peer into space with massive cameras.
And you don’t need to be a scientist to take part.

If you’re lucky enough to have no clouds or rain, that is.
Things the eclipse affects:
Things scientists can view thanks to an eclipse:
The East Coast of North America, where most of my relatives live, is currently 13 hours behind me in Japan. So the event will be long over by the time I wake up.
Hope to see video of it on the morning news show tomorrow!

Water molecules have been detected in asteroid samples returned to Earth, but this marks the first time that the molecules have been discovered on the surface of an asteroid in space. The team studied four silicate-rich asteroids using data from the now-retired Stratospheric Observatory for Infrared Astronomy(SOFIA).
https://www.popsci.com/science/water-asteroid-space/
The asteroids in question are Iris (124 miles / 200 km in diameter) and Massalia (84 miles / 135 km). Both are in the asteroid belt between Mars and Jupiter. Iris is about the size of the US state of Maryland, while Massalia is roughly the size of Connecticut.
Note that the same observatory also found water on the Moon, about a “12-ounce bottle” worth. Not nearly enough for a settlement, but where there’s surface water (albeit trapped in soil on the surface), there’s likely to be more underneath.
(See also https://www.swri.org/press-release/swri-scientists-identify-water-molecules-asteroids-the-first-time — the PopSci linked article above essentially plagiarised almost its entire text. Bad scientist, bad.)
Original article here: Arrendono et al. (2024) Detection of molecular H20 on nominally anhydrous asteroids. Planet. Sci. J. 5. 37 doi 10.3847/PSJ/ad18b8 – good luck trying to read it!

“It should be able to make a smarter AGI, then an even smarter AGI, then an intelligence explosion,” he added, presumably referring to the singularity.

Seriously. Am I the only one who thinks this is, like, a really, really, REALLY bad idea?

Hello, everyone, and thank you for reading!
This is a short (~8 minute) video I made to introduce the story Bringer of Light.
I’ll be posting a couple more videos in the near future about the characters, location, and science behind the story.
Check it out, and share freely!

A robotic spacecraft made history Thursday becoming the first privately built craft to touch down on the lunar surface, as well as the first American vehicle to accomplish the feat in more than 50 years.

Congratulations! 🎉
You now have one week before shutting down permanently.
Jeez. Really? That’s a very expensive week at $118,000,000. Glad the taxpayers approve (?)

OK, so my post about a big ole spider got the most likes of any post in ten years of blogging about science.
I have so not got the zeitgeist of the 2024 blogosphere lol – anyway, thanks, all, for the “likes”! Although one person used AI to write a very meaningless comment about arachnophobia. What’s the point, man?
By the way, back to science and space stuff. I forgot to post about the Europa Clipper project back in October.
So here you go. (It’s too late to add a message, but the project obviously is going to take some time arriving there, and you can supposedly hear US Poet Laureate Ada Limón read her poem online, although I’ve had trouble with the audio lately:
“Arching under the night sky inky
with black expansiveness, we point
to the planets we know, we
pin quick wishes on stars. From earth,
we read the sky as if it is an unerring book
of the universe, expert and evident.
Still, there are mysteries below our sky:
the whale song, the songbird singing
its call in the bough of a wind-shaken tree.
We are creatures of constant awe,
curious at beauty, at leaf and blossom,
at grief and pleasure, sun and shadow.
And it is not darkness that unites us,
not the cold distance of space, but
the offering of water, each drop of rain,
each rivulet, each pulse, each vein.
O second moon, we, too, are made
of water, of vast and beckoning seas.
We, too, are made of wonders, of great
and ordinary loves, of small invisible worlds,
of a need to call out through the dark.”

The craft is at a very awkward angle. A picture, captured by the small baseball-sized robot called Sora-Q – which was ejected from Slim moments before touchdown – showed the lander face-down on the lunar surface.
That left its solar panels facing away from the sunlight and unable to generate power. The decision was taken to put the lander into sleep mode – and conserve what power remained – less than three hours after it landed.
That tactic appears to have worked. A change in the direction of the sunlight has now “awoken” the craft.
https://www.bbc.com/news/science-environment-68131105
As previously reported, JAXA did achieve its goal of a “precision landing” — as some put it, a “pinpoint” touchdown within 100 meters of the intended target — within 55 meters, although if all had gone as planned, it would have been within 10 meters.
That’s far, far closer than previous Moon landings.
Too bad SLIM is essentially standing on its nose. But at least this is a beginning. Japan has now become the fifth country (US, USSR, China, India) to successfully “soft land” an object on the Moon.
And the robots it brought with it are pretty amazing. And tiny.
