We could live together / crystals on the Moon…

September 18, 2022

Half of a dilithium crystal? (It’s a new type of crystal called “Chang’esite” (after the ancient Chinese moon goddess).

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…

Spectacular image of Jupiter’s auroras and moons

Courtesy NASA. Note that the blue, white, green, yellow, and orange colors are artificial, only added to make features revealed by infrared stand out for human eyes. You can see the planet’s rings, aurora, and two “tiny” moons (at left; they’re not really that tiny!).

“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).

Will NASA call it all off? PSYCHE!

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…

Looking for aliens in all the wrong places?

August 12, 2022

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.

International asteroid day!

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.

Amino acids found in material brought back by Hayabusa-2

June 6, 2022
MThomas

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.

https://english.kyodonews.net/news/2022/06/9a7dbced6c3a-amino-acids-found-in-asteroid-samples-collected-by-hayabusa2-probe.html

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…)

Plants can grow in lunar soil (barely)

May 16, 2022
MThomas

Doesn’t look too terribly attractive…

The samples were extremely hydrophobic, and repelled water as if it were the most disgusting thing ever invented. Researchers labored to get the lunar soil to gradually soak up water. They also added a nutrient solution.

https://www.washingtonpost.com/science/2022/05/12/plants-grow-in-lunar-soil/

Turns out that it is possible to grow plants on the Moon…

…although you might want to wear gloves while farming, since the “soil” contains tiny pieces of glass from constant bombardment.

Why do all the planets orbit the sun in the same direction?

April 16, 2022
MThomas

Note: not to scale (duh). Thanks, Getty. Uh, is this really the best way to show the solar system? (There…are…NINE..planets!)

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 Ibet now you’re all thinking of pizza… 🍕

Let’s make rocket fuel with E. Coli!

April 12, 2022
MThomas

In short, the algae will use sunlight to transform CO2 into sugars that are then enhanced by bio-engineered E.coli into 2,3-butanediol. Interestingly, 2,3-BDO is not entirely conceptual as it currently exists and is mainly used to produce rubber components. It has just never been thought of as fuel before.

https://www.universal-sci.com/article/producing-rocket-fuel-on-mars-using-microbes?utm_campaign=Universal-Sci%20Weekly&utm_medium=email&utm_source=Revue%20newsletter

Neat. So all the astronauts have to do is bring, uh, how much algae we talking here?

The article doesn’t say, but it does mention a by-product of the process: Oxygen!

That would seem rather helpful. Mars or bust?
