“For the first time ever, humanity has changed the orbit of a planetary body,” said NASA planetary science division director Lori Glaze.

A change of 32 minutes in orbit — but only 4% of the total orbital period. To deflect an asteroid away from Earth, it’d better be done several years in advance. 🌏
Still, it can be done. An amazing first.

Remember, it’s a video on TikTok, so it must be real. (link below to The Independent, a completely trustworthy sources of snarkiness).

Just passed 200 followers on WordPress. Thank you, everyone!
I know I should be posting a whole lot more often than I have. There are LOADS of new science articles and events happening recently, so I’ll see if I can get caught up over the next couple of weeks.
Plus a new chapter of Bringer of Light by the end of the week! I promise!
(And it would be VERY helpful if WordPress didn’t “refresh” while I was adding tags and categories to posts, and then hiding those tags and categories afterward so that I couldn’t update them…Sigh…what was wrong with the older version that worked just fine?)

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.
So here’s an article about what Chinese scientists found in Moon dirt.
Also H3. Yay. Let’s make fusion reactors and walk on the Moon together…

This is how good our local hospital reception used to be.
(Pre-pandemic photo, 2015 or 2016. I think it’s been fixed since then. Shortly after I took this photo we started going to another hospital instead…)

“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.

So is asteroid worth it?
Sure.
Is it horribly expensive right now?
Sure.
So why do it?
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.

I agree that we are biased, simply based on the basics of what we understand as (carbon-based) life (i.e., ourselves).
And I agree — in principle — that scientists need to keep an open mind when looking for other life forms on exoplanets.
However, they also need to retain a sense of skepticism.

If successful, it will join spacecraft from the U.S. and India already operating around the moon, and a Chinese rover exploring the moon’s far side.
