“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).

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…

Yeah. So I missed another installment in my series.
Shoot.
Things are just ridiculously spiraling out of control at work. I hope to start posting more regularly again in a week or so.
In the meantime, check out more images from the Webb space telescope compared to Hubble. They’re pretty awe-inspiring.

Today is “International Asteroid Day”!
Who knew?
Asteroids hold large amounts of valuable minerals and metals. That is what International Asteroid Day is raising awareness about on 30 June.

More than 20 types of amino acids have been detected in samples Japan’s Hayabusa2 space probe brought to Earth from an asteroid in late 2020, a government official said Monday, showing for the first time the organic compounds exist on asteroids in space.

This lends support to the hypothesis that life on Earth was brought to it during the Late Heavy Bombardment period – in which meteors brought not just water but the building blocks of life…
Now imagine if someone were to find an asteroid with addition proteins NOT found on Earth… (i.e., my novel’s scientific premise…)

A new study suggests that 16 Psyche, one of the most intriguing and most valuable asteroids we know of, could be covered in iron-spewing volcanoes.

Psyche is an asteroid that was probably once the heart of a planet in the early system, one that didn’t survive the violent process of planet formation.
Yep — that “worth more than the global economy” rock in space.
But we’ll have to wait a few years to find out if it’s “less metal and more hard rock” — the Psyche Mission rockets off in August 2022 and the probe won’t arrive for four more years.

Technically, the two asteroids the DART is aiming at are a “binary” (they orbit each other).
The BBC’s explanation is pretty good.
They don’t even mention Bruce Willis until the final sentence.

Where’s the Artemis?? What’s up with Mars? And Ceres seriously…?
Sorry I haven’t kept up the story posts, everyone.
I know it’s been almost a month since the last Bringer of Light episode. Work just got dumped on me, and I can barely find time to give my writing students feedback. We switched back to face to face classes…with live streaming on Zoom for students who couldn’t or wouldn’t go back to campus…which is definitely NOT a teaching style I would recommend to anybody, anywhere, ever.
It’s been like laying down tracks in front of an oncoming train. Every day.
There is lots more good stuff for Riss and her crew, I swear. I’ve got drafts up to Chapter 42, and plots to the end after that. Let me see if I can get the next one up for you all in a day or two…

OK, I readily admit that I am once again waaaay behind on my scifi blogging.
At some point last week, I looked up from the mass amounts of work I had left to do and went, “Uh. August 21st? Was that really the last time I posted?”
Uh. Yup.
😣
I’ll do my best to get the rest of Riss’s story online on a biweekly basis, like I promised I would.
But promises…
