Spectacular image of Jupiter’s auroras and moons

August 23, 2022

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…

Another month, another missed Bringer of Light post…

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.

Plants can grow in lunar soil (barely)

May 16, 2022

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.

“Make Uranus mission your priority” –uh, for what practical reason?

April 30, 2022

Researchers think an in-depth study of Uranus can help them better understand the many similarly sized objects now being discovered around other stars.

https://www.bbc.com/news/science-environment-61155725
Uranus’s strange tilt is probably due to getting smacked by a very large body a long time ago…

Uranus is weird. It has rings. It has 13 moons, some of which may harbor life beneath their icy surfaces.

It has a funny name.

I get it. But learning more about how its formation affects planet formation is just not that important.

“Pure” researchers probably are interested, but frankly, if NASA wastes its time doing this, they will miss the opportunity to settle the Moon and Mars, mine asteroids for valuable resources, and explore other moons like Titan and Europa.

China will get there first.

Pure research is all fine and dandy, but it’s also incredibly expensive — taxpayer dollars should be spent on projects with more tangible benefits.

Largest comet ever seen barreling through the solar system

April 18, 2022
MThomas

C/2014 UN271 on the far right has a nucleus 50 larger than the average comet.

“Its size, which NASA noted is larger than the state of Rhode Island, is an estimation because the comet is still too far away for Hubble to tell for certain.”

https://www.businessinsider.com/largest-comet-ever-seen-barreling-toward-inner-solar-system-nasa-2022-4

Note that the original title was “…toward the Inner Solar System”…and yet the article goes on to explain that it won’t come any closer than a billion miles from the Sun, “‘slightly farther than the distance of the planet Saturn,’ NASA said in a statement.

Uh. The inner solar system is *no where near* Saturn. Try again, fear-mongers.

Sigh.

Anyway, it really is the proverbial “tip of the iceberg,” since this was seen with Hubble, and we have yet to see just what the new James Webb telescope can do. The Oort Cloud is a big place. There must be millions upon millions comets just waiting to be discovered.

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?

How do you do it without gravity?

Or, as I’m sure was unintentionally titled, ”Nasa probing people having sex in space.” 🤦

Ya know, I’m pretty sure we need to figure out “this whole food-air deal” first (to quote comedian Bill Hicks).

“The US space agency confirmed that there were currently no plans for a field or project office to explore the topic in any detail but that could change as we get closer to putting humans on Mars.“

Uh-huh.

Priorities…

Psyche! It might not be as heavy as we thought

March 4, 2022
MThomas

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.

https://www.forbes.com/sites/jamiecartereurope/2022/02/24/the-iron-giant-asteroid-worth-more-than-our-global-economy-may-have-an-explosive-secret-say-scientists

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.
