Science fiction, actual science, history, and personal ranting about life, the universe, and everything

Remember the Titan! Uh. The moon. Called Titan.

Cyclopropenylidene is the second cyclic or closed-loop molecule detected at Titan; the first was benzene in 2003. Benzene is an organic chemical compound composed of carbon and hydrogen atoms…Cyclic molecules are crucial because they form the backbone rings for the nucleobases of DNA, according to NASA.

The only moon in the solar system that has an atmosphere…4 times denser than the Earth, actually.

Except it rains ethane and methane and is -270C. Not exactly a place to plan a vacation.

But the organic molecules may (BIG may) hint at life of some sort.

And we only have to wait until 2034 to find out!

The Great Conjunction of 2020 is coming!

November 3, 2020

On the the exact date of the winter solstice, Jupiter and Saturn appear closer together in the night sky that and at any point since July 16, 1623.

Mars to the East, Jupiter to the South…hey, is that a Saturn?

Also, go over to https://www.theplanetstoday.com to see how Jupiter and Saturn are both currently in a heliocentric conjunction (i.e., lined up with the Sun) on November 2nd.

Psyche! Uh, no, sorry, that’s not really how “value” is determined…

“Artist’s depiction” = “we don’t really know, actually, but isn’t this cool?”

Even more intriguing, the asteroid’s metal is worth an estimated $10,000 quadrillion (that’s 15 more zeroes), more than the entire economy of Earth.

https://www.usatoday.com/story/news/nation/2020/10/29/metal-asteroid-psyche-nasa-hubble-images/6069223002/

Leave it to USA Today—the paragon of journalistic integrity and unvarnished truth reporting—to grossly exaggerate “value.”

Imagine if someone dumped several hundred thousand tons of nickel and iron on the market?

It would immediately make nickel and iron worthless. Simple supply and demand. So it’s not monetary value that is important.

How do we create vehicles and domiciles for a space-faring future while avoiding the exorbitant cost of getting them into space in the first place? It’s the cost and weight of rocket fuel that’s the issue.

Solution: Build everything in space. No need to bring anything back to Earth.

Not needed now. Maybe someday.

Use a human language, preferably…

Dropping a shoutout to all my followers, old and new. Thanks for reading!

I’m preparing this week’s installment of Bringer of Light (Chapter 3, Part 2), all the while scouring the web for science and tech news to share.

Anything you want to see shared (or want to share)? Comments on the story so far? Something you want to rant about? (No politics please! Waaay too much of that at home right now. I’d rather keep my head in the stars when possible…)


Bringer of Light: Chapter 3, Part 2 – dropping at 7 p.m. EDT October 31st. No Halloween theme, sorry (that’s a separate post 🎃).

Wishing our base away…water on the Moon?

October 26, 2020
MThomas

The new research is especially topical given that NASA plans to land humans on the Moon in the 2020s and use lunar resources as part of its Artemis program, prompting thorny discussions about legal and ethical extraction of materials on the Moon.

“Micro cold traps.” The equivalent of a 12-ounce bottle in a cubic meter of soil. But not everywhere, and primarily at the polar caps.

So…how will this help, exactly? 🤔

Bringer of Light Chapter 3 — The Artemis (Part 1)

October 24, 2020
MThomas

(This week’s installment is over 3000 words long, so I’m splitting it into two parts for posting. Enjoy!)

“Airlock 2 engaged,” came the navigator’s voice over their helmet comms. “Seal confirmed.”

“Thanks, Enoch,” Riss replied. “Take up your position on the catwalk.”

“Roger.”

Riss removed her helmet and placed it on top of the cargo hold’s control computer stack. Riss surveyed the hold. Designed to safely transport small to medium-sized asteroids, the vast space was shaped like top half of a dodecahedron. Which, in fact, it was. The bottom half comprised the fuel storage for Artemis’s ion engines.

Behind the control computers, the main door to the hold remained closed. Wrapped around the entire cargo hold area, the walkway could be accessed only through a small square portal directly above the main door.

The hold had two access ports. Port-side, Airlock 1 was reserved for the Hopper. Starboard-side, Airlock 2 served as a backup. Riss hated using it. While Airlock 1 was almost flush with the floor, Airlock 2 was several centimeters up the wall. After several initial attempts trying to leave the airlock without spraining an ankle, she decided never to use it for the Hopper. On the other hand, the airlock was perfect for unwanted guests.

Riss motioned for Sanvi and Cooper to stand at either side of her. She readied her sidearm, an old tazer rifle. Riss prayed she wouldn’t have to use it. From the sound of things, Gennaji must still be holding the old grudge, from near the end of her time on the Sagittarius.

At the thought, her eyes hardened. Lena, I’m sorry.

Bringer of Light – Chapter 1. The Rock

October 10, 2020

The horizon felt so close on the asteroid, the area around her illuminated only by the Hopper and her own helmet light. Everything else—darkness. Clarissa imagined herself stepping off into space, arms outstretched. Floating…

She shook her head. She ought to return to the Hopper in case a rival hunter ship arrived. Even this far in the trans-neptune system, she didn’t have the luxury of fantasizing on the job. Her crew deserved better. She bounded back to the small reconnaissance craft.

“Captain,” came a deep East African voice over her helmet comm. “How much of a sample do we need to lay claim?”

“At least two tubes, Coop. I can give you a hand if you need.”

“I’m the astrogeologist, right? I can handle it.”

“All right, geist. Just make sure to keep your gravboots on so you don’t float away like last time.”

“Like, like last time? Wh—”

Get your telescopes out, the solar system’s largest volcano is here!

October 9, 2020
MThomas

The volcano is about the size of Arizona with a volume 100 times larger than that of Mauna Loa’s, Earth’s largest volcano, NASA says. “In fact, the entire chain of Hawaiian islands (from Kauai to Hawaii) would fit inside Olympus Mons!”

Brighter than Jupiter this October! And the closest Mars will be until 2035.

“Weird space” beyond the heliosphere

October 3, 2020
MThomas

“When you look at different parts of the electromagnetic spectrum, that area of space is very different from the blackness we perceive with our eyes,” says Michele Bannister, an astronomer at the University of Canterbury in Christchurch, New Zealand, who studies the outer reaches of the Solar System. “Magnetic fields are fighting and pushing and tied up with each other. The image you should have is like the plunge pool under Niagara Falls.”

Children of Pella — to post or not to post?

September 14, 2020
MThomas

OK, so I admit it — I’m way behind in finishing my SF novel, Bringer of Light (you can read the prologue here).

I had hoped to get the draft done by January, then work on edits in the spring and publish it in summer.

But a little COVID happened to the world, and believe it or not I got a little sidetracked by, uh, life. And a family history project about a love triangle (kind of).

(During our two-month quasi-lockdown-not-sure-what-this-is-stuck-home-with-two-kids thing, I did get pretty good at the Mars terraforming game. Highly recommended.)

So now I’m thinking, to kickstart my writing life back into action, why not post the chapters I have so far? There are about 35 of them, tend to be short, and since I’ve been struggling with the ending, might help generate some ideas for getting to the expected final scene.

Sound like a good weekly post?
