Lots and lots and lots of space stories occurred in 2022.
From DART to Landsat, Sagittarius A* black hole to CAPSTONE, the Korean Pathfinder to SpaceX, and to the ISS, Moon, and Mars, here’s a summary of major space exploration projects last year.
Looking forward to 2023 and beyond!

Mission success would also be a milestone in space cooperation between Japan and the United States…
https://www.yahoo.com/news/japans-ispace-readies-delayed-launch-220204283.html
OK, wait…
A Japanese start-up (I.e., a small private company)…
using a SpaceX rocket (I.e., a private company owned by the world’s wealthiest pri…er, person)…
sends up a small craft made in Germany… 🇩🇪
along with the Rashid rover (made by the UAE)…
and “a two-wheeled, baseball-sized device from Japan’s JAXA space agency”…
and somehow this is cooperation between the US and Japan versus China and Russia?
I’m not seeing it. The project may have used a NASA launchpad, but the people are charge (and the ones paying for it) are not part of any national government.
And I have a feeling this is the wave of the future. More and more private companies will get involved in space projects as they realize that they can thus ignore politics and aim at profits.
I, for one, welcome our future corporate overlords…

Think of pizza dough flattening into an enlarging disk as it’s tossed. Because the cloud had an initial rotation, this same direction of spin has persisted…
https://www.popularmechanics.com/space/solar-system/a39729213/why-do-all-the-planets-orbit-in-the-same-direction/
So basically the answer is simply that that’s the way they all started out.
Some moons, however, do have retrograde orbits. I.e., they orbit in the opposite direction around their respective planets. Some small asteroids and comets also have retrograde orbits due to their small mass being easily affected by larger cosmic objects.
But I bet now you’re all thinking of pizza… 🍕

Just saw someone on my morning commuter train wearing a fluffy beige coat with a single word in all capital letters, stretching across the back from left elbow to right elbow:
EXPLOIT
Yeah. That’s what happened, alright.

On Tuesday as I was walking back from work, much later than usual, my shoes were bothering me.
They felt stretched, loose, especially irritating on a rainy day.
I had spent too much time polishing them, I thought.
Too much effort making them “waterproof.”
Too much money on these damn useless things.
I resolved to throw them away and get a new pair.
But of course it would take time, and money, and effort to go get them.
Damn shoes. I would have to rearrange my entire week because of you.
The next morning, as I put my shoes on, I realized that the laces were loose.
So I re-tied them, and instantly they felt better.
Sometimes, when a small, insignificant problem arises, there is a simple fix.
Think small.

Only 1600 light years away!
And it’s a binary system. Very odd.
It’s also “dormant.” Even stranger.
Ten times the size of our Sun, as far away from its companion star as the Earth is from the Sun.
Announced just in time for Halloween…

“For the first time ever, humanity has changed the orbit of a planetary body,” said NASA planetary science division director Lori Glaze.
https://www.sciencenews.org/article/dart-mission-deflected-asteroid-for-planetary-defense
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.

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…

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.
https://www.thedailybeast.com/alien-hunters-need-to-start-rethinking-the-definition-of-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.
