Geminids, Geminids, Geminids!

December 15, 2025

It’s been several months since I last posted…too much work and no play!

Until this past Sunday. Whew.

After a morning lecture about ancient Japanese myths and “deliberately forgotten” kings (maybe), I was grateful to be able to take a quick power nap…

…so that the family could go up a nearby mountain and watch the Geminid meteor shower. (By “mountain,” I mean about 640m/2100ft.)

After a brief lecture/quiz by a staff member at our local culture center, we stayed outside, lying flat on the ground, for over an hour. And, yes, it was cold, despite the sleeping bag and thermal underwear. I saw three shooting stars. Not nearly as many as I’d hoped.

After we got home and took evening baths, the kids went out on our second-floor balcony and found out that the night view was even better at home than on top of a mountain! At least they knew what to look for, thanks to the culture center event.

Although the peak is Sunday night between midnight and 2 a.m., the meteors are still visible to some degree the rest of this week.

And by “meteor,” I mean the size of grains of rice. Look to the eastern sky, just a bit to the northwest of Orion, to find the Twins (Castor and Pollux in Greco-Roman mythology).

For more on the origins of the Geminids, check out the JAXA mission to Phaeton, the parent body asteroid. It’s DESTINY!

Long time, no…

Hi, everyone. I haven’t written a blog post in a very long time.

For various reasons.

I’ll see if I can start posting a few entries on recent science events in a few days (for starters, four astronauts finally arrived at the ISS, the first replacements following the Boeing Starliner fiasco).

But for right now, I want to follow up this short post with some analysis I got from our friend ChatGPT…

…about Adam’s Stepsons and Bringer of Light. Stay tuned!

Japan launches world’s first wooden satellite

November 12, 2024
MThomas

Researchers at Kyoto University who developed it hope it may be possible in the future to replace some metals used in space exploration with wood.

The researchers argue that “if” trees could be planted on Mars…

OK, just stop right there. I’m pretty sure Mars will struggle to support even grass, let alone trees.

And the argument that, due to a lack of oxygen, flammable wooden structures in space would not be in danger strikes me as a bit ludicrous…surely there would be oxygen inside the wooden structures?

And, you know, I do think I’ve seen this before some where…nah…

Boeing Starliner delayed. They should delay again.

A contractor for Nasa urged the space agency to conduct more safety checks before the highly-anticipated first launch of its Starliner rocket – which is set to take off as soon as next week – “before something catastrophic happens”.

https://www.independent.co.uk/tech/nasa-contractor-boeing-starliner-launch-b2542947.html

It was supposed to launch last week, but someone spotted a valve problem — *minutes* before the countdown procedure was about to start.

They’d better check for door plugs while they’re at it.

Boeing does not give a rat’s ass about whoever uses their products. They‘re only interest in paying dividends to stockholders. And of course paying the CEO’s ridiculously high salary.

NASA is trusting the future of space travel to people like Musk and companies like Boeing. Using taxpayer money to reward greed and incompetence.

We can do better than this.

Nuclear power on the Moon. Gee, no problem…

May 13, 2024
MThomas

The South Pole, where power plants are likely to be constructed (without human help…)

“The truth is that nuclear is the only option to power a moonbase,” says Simon Middleburgh from the Nuclear Futures Institute at Bangor University in Wales.

https://www.bbc.com/future/article/20240417-the-nuclear-reactors-that-could-power-moon-bases

So far there are two major consortiums that have plans for moon bases:

The Artemis Accords, with 36 countries (the US, Japan, South Korea, UAE, India, etc.)

The countries that don’t like the US, the UK, and Canada (China, Russia, Belarus, Venezuela, Pakistan, South Africa, Egypt, Ajerbaijan)

OK, maybe a bit of an exaggeration, granted.

But there is no doubting the political ramifications of two competing groups of astronauts (cosmonauts, taikonauts) on the Moon.

And just wait until they get to Mars.

Imagine what might happen. (I did!)

“May you live in interesting times…”

Can you say “Catch-22” in space?

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?

Bringer of Light: Background Notes (1)

February 21, 2024
MThomas

It’s been well-known for some time now that the building blocks of life called amino acids can be found on asteroids strewn throughout the solar system.

It’s also thought that water on Earth is largely (or entirely) the result of comets and asteroids bombarding it (it remains debatable to what degree Earth already had water, but since when it formed the Earth was first molten lava and then dry as a bone, I think it far more likely that water came here from elsewhere, and science tends to agree).

I’ve already blogged about the origins of Bringer of Light, when I (finally) finished the first draft back in early September. In a sense, I’ve been constantly blogging the science behind the story.

But I haven’t discussed the characters at all. And despite what some old-fashioned writers may think (just finished a particularly badly-written snarky “why your books don’t sell” piece of trash that claimed science fiction shouldn’t have any emotions in it…say what? sorry not sorry), if the characters of a story aren’t interesting, there isn’t much point in reading a story.

So for the next couple of weeks, I’ll write a bit about the characters — the crew of the Artemis, the crew of the Sagittarius, the UN flunkies (sorry, career politicos) on Mars and Luna and so forth. There are lots of characters, and their interaction is complicated. Or is it?

I would get into my scifi influences at this point, but long blogs are slogs. So I’ll come back to that tomorrow!

Coffee time. Also to finish up at least one unrelated project and also the hardcover manuscript (which needs to be a different paper size than the paperback for some reason).

SLIM pickings! Back to work…

January 31, 2024

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.

Newly discovered cosmic megastructure challenges theories of the universe

January 23, 2024
MThomas

The so-called Big Ring has a diameter of about 1.3bn light years, making it among the largest structures ever observed. At more than 9bn light years from Earth, it is too faint to see directly, but its diameter on the night sky would be equivalent to 15 full moons.
https://www.theguardian.com/science/2024/jan/11/newly-discovered-cosmic-megastructure-challenges-theories-of-the-universe

This is important because it contradicts the so-called “cosmological principle” that everything in the universe is basically evenly distributed.

Just thinking about it, though, it makes little sense to assume that galaxies are all evenly spaced. Assuming the Big Bang was a single point should not imply even spacing of anything.

FWIW the “Big Ring” is evidently more a corkscrew shape, directly aimed at us. Evidence of “cosmic strings”? Maybe.

This is not as interesting as technology that will allow us to build hotels and colonies at LaGrange points or communities on Mars, but it’s still interesting. Sorta. Maybe?

Japan lands on the Moon — for just a few hours

January 20, 2024
MThomas

A Japanese robot has successfully touched down on the Moon but problems with its solar power system mean the mission may live for just a few hours.

The Smart Lander for Investigating Moon (Slim) put itself gently on the lunar surface near an equatorial crater.
https://www.bbc.com/news/science-environment-68035314

Or SLIM, if you want to actually write acronyms properly (snark).

Also, it’s JAXA, not Jaxa. And NASA and ESA, not Nasa and Esa. But I digress.

Anyways, kudos but too bad yet another space mission failed. At this point I’m wondering how on Earth NASA managed to land people on the Moon so successfully in the 1960s and 1970s without killing half of them in the process. We can barely manage to get a tiny robot rover the size of a marble to land (see the link above for the picture of the “hopper” and “shape shifting” ball…curious about the “shape shifting” bit…)
