“Rock. Rock. Rock. Rock. Rock. Rock. METEORITE!”

March 7, 2023

The mysterious object’s lovely silver metallic hue stands out like a sore thumb in the surrounding, rust-colored landscape, a sulfate-bearing region of the Red Planet’s Mount Sharp.

Yes, they’re actually calling the meteorite fragment “Cacao.” Sigh.

Too bad Curiosity can’t take any samples. Perseverance can, but it’s too far away.

Curiosity has stumbled across several other such rocks previously, like “the Beast” and “Lebanon.” Sadly, none can be dated.

But the fact that there are so many of these impacted on the surface of Mars shows additional risks that any human mission might face…

Rich people don’t even see money. All they know is…

Lots and lots and lots of new rockets in development now.

And the most well-known of the newbies is…

(Click here for a closer look at a rich man’s dream rocket.)

Also, see this one (pay wall, Washington Post) about NASA and DARPA working on one to reach Mars much faster to reduce astronauts’ exposure to radiation.

I still think “durp” every time I see that acronym 😝

Bringer of Light, Chapter 38 (Part 2): United Mars Colonies — Cut the Tether (this time for good!)

February 4, 2023
MThomas

Concerned that the UA forces on Luna Base may use the quantum teleporter to send an unwelcome gift to the newly-declared independent United Mars Colonies, former Mars security chief Sergeant Major Hamels and former Artemis crew members Enoch Ryan and Brady Cooper attempted to disable the teleporter ahead of time.

Too late…

Cooper could sense the radioactive isotopes within the canister. The explosive materials could kill them and most of this part of the colony due to sudden decompression of the building’s atmosphere. Fine radioactive dust spread everywhere. If it reacted with the cobalt in the boxes around them, the resulting dirty bomb could poison half or most of the planet for years. Decades, even. Who knows how long it would last.

If anyone were around to care.

“Fly-boy, you sense that?”

“Yeah.”

“Let me try something.”

“You want the rifle?”

“The energy discharge will just set it off. That’s probably what they were counting on. Or hoping we’d try to disable it.”

“Or send it back,” Hamels said. “No doubt their end has a rigged signal to reject contact, which also would set the thing off.”

“Then there’s only one option.”

With a sigh, Enoch set the rifle down next to the console. “Coop, something tells me you need me to help.”

“You read my mind.”

“Not yet.”

Now it was Hamels’ turn to back away. “What are you both doing?”

“Sergeant Major, we need you to focus on maintaining the force shield.”

The geist sat down crosslegged on one side of the platform. Enoch sat down likewise across from him on the opposite site. They stared into the force shield, concentrating on the cylindrical container.

“What are you doing?!” Hamels repeated.

“Changing it to uridium,” Cooper replied.

Confirmed: We’re all here thanks to asteroids

January 26, 2023
MThomas

Since the Hayabusa2 returned with the sample from the Ryugu asteroid in December 2020, several important discoveries have been made – most notably analyzes confirming the presence of substances thought to be the building blocks of life on the asteroid, such as liquid water and organics fabrics.

https://newsbeezer.com/germanyeng/ryugu-asteroid-helps-unravel-the-origin-of-life-on-earth/

Hayabusa-2 took several years to land on Ryugu (literally “Dragon Palace”), pound out just over 5 grams of asteroid material, and bring it back to Earth (landing in Australia in late 2020).

NASA scientists have confirmed not just frozen water but liquid — inside crystals called pyrrhotites. JAXA scientists (pictured above with Prof Tsuchiyama of Ritsumeikan University, my main employer!) continue to check the density of the samples.

The water is similar to the carbon dioxide-laden water of hot springs. The research teams have already discovered over 20 amino acids, the basic protein building blocks of carbon-based life.

Another theory called “panspermia” proposes that a key mineral (boron) missing on early Earth came in an asteroid from Mars. ☄️ Hmm. Did Mars produce asteroids? Or more like asteroids hit Mars and broke off lots of tiny fragments? That somehow survived the journey to Earth?

Seems a little unlikely. But there is now evidence that at least some proteins came from space rocks.

So, sorry, Ridley. This isn’t how it happened. Cool movie, though.

What is this “Cislunar” space?

January 24, 2023
MThomas

Though definitions sometimes differ, cislunar space generally refers to the space between Earth and the moon, including the moon’s surface and orbit. Any nation or entity that aims to establish a presence on the moon, or has ambitions to explore deeper into the solar system, has a vested interest in operating in cislunar space, either with communication and navigation satellites or outposts that serve as way stations between Earth and the moon.

https://www.nbcnews.com/science/space/space-earth-moon-get-little-crowded-rcna64333

There is actually a limited amount of orbital space available between the Earth and the Moon (note: capitalize it, NBC! grrr..).

So, expect more and more competition for satellites — communication, navigation, and way stations.

And of course military and spy stations.

And by the way, only eight nations signed the so-called “Artemis Accords” in 2020. Guess who didn’t?

Buckle up!

Bringer of Light, Chapter 38 (Part 1): United Mars Colonies — Cut the Tether

January 7, 2023
MThomas

This installment is a bit longer than anticipated, so I will cut it into two parts. Metaphorically. Just like the Artemis crew will need to, following their agreement with the Mars colonies faction heads to train the afflicted settlers in controlling their odd new powers and sensations while assisting in distribution of temporary water and food supplies. Only Martin, the former Mars UN Overseer, who thinks he can manipulate the situation, is about to find out things are proceeding far faster than he planned. And Luna Base has a nasty surprise in store for Mars…

The storeroom chambers were nearly full by now. It had taken several days, but at last the food and water brought from Ceres had been stacked neatly, carefully portioned and labelled for each settler division. Orders were sent to each settler node requesting two or three representatives to bring their respective robotic platform dollies to the main supply chamber.

Cooper strolled casually along one earthen wall, rubbing a hand against the soil. He could feel the regolith composite materials, sense the minerals and hydrocarbon content. It would be so easy to extract and solidify what they needed, strengthen the structure. Or dig even deeper below the planet’s surface.

“Here,” Martin said, handing a pad to Cooper. “I’ve authorized the complete list of supplies brought by the Artemis. There’s my thumb verification, at the bottom.”

Cooper accepted the pad. He scrolled up to verify, nodding. “That should do it.”

“Now,” Martin said, addressing both Artemis crew members with him. “I’d like to find out what happened to my security chief, Hamels. She was outside the airlock when you dropped the ditrium on the ice cap.”

“First things first,” Enoch said. “We’d better make sure that the quantum teleportation nodes from Luna are severed.”

“Severed?”

“Yes. Completely.”

Martin turned pale. “That would seem a bit, er, final, wouldn’t it?”

Enoch grinned. “You bet. And necessary. Who knows what might come through the next time the UA turns the system on again?”

“Meaning?”

The geist spread his hands wide and made a booming sound, then laughed. The tall spacer slapped his crewmate on the shoulder, then both laughed hysterically for a moment. Martin stared at them. Cooper couldn’t help doubling over again, holding his stomach.

The 2022 Year of Space Exploration

January 2, 2023
MThomas

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!

What does a dust devil on Mars sound like?

December 21, 2022
MThomas

It was “definitely luck” that the dust devil appeared when it did, said the study’s lead author, who estimates there was just a 1-in-200 chance of capturing the audio.

https://www.nbcnews.com/science/science-news/mars-rover-captures-first-sound-dust-devil-red-planet-rcna61642

Perseverance has been on Mars for almost two years now, and already recorded wind on Mars for the first time in February 2021.

This dust devil was recorded in late September 2021 (wonder why only now it’s being revealed?). The dust devil was “average size,” which is described as about 400 feet / 122 meters tall and 80 feet / 24 meters wide, traveling at 16 feet / 5 meters per second (≈ 11 mph / 18 mph).

UPDATE. NBC incorrectly reported in the above linked article that the dust devil was recorded by Perseverance. It was actually recorded by InSight, which has just fallen silent after four years of operation. Sigh. I should get science news directly from the source and not from unreliable “news” sites.

There are a lot of dust devils on Mars. A whole lot. Any settlement would have to be extremely prepared to deal with dust all the time, everywhere. If it ever got into equipment that regulated, say, breathable air inside habitats…

From nothing to Mars in 6 years

In 2020, the UAE’s space agency launched its first Mars mission, less than a decade after it was created. How did they manage it?

https://www.bbc.com/future/article/20221206-how-the-uae-got-a-spacecraft-to-mars-on-the-first-try

This is a great story about how true international cooperation rather than competition can result in scientific progress.

Thanks to their efforts, despite nearly being derailed thanks to the pandemic, we will soon have a complete picture of an entire year of Mars weather.

Not bad for a country whose space agency is so small “you could probably lose it in the car park of Nasa’s giant Johnson Space Centre in Houston.”

(Of course, the project’s findings may mean I have to rewrite some of my novel in progress, but why not? All in the name of science fiction…)

Bringer of Light, Chapter 37: Transit Ceres to Luna

December 10, 2022
MThomas

In a story long, long ago…

Sorry that it’s been almost three months since posting more fiction. The colonists on Mars are still undergoing training by Riss and Sanvi so that they can understand and control their new abilities. Meanwhile, Bardish has headed out into space, where he met his destiny.

And Gennaji, who had been headed to discover Bardish’s fate on Luna, is now approaching his own.

“Prepare to board that Loonie ship,” Gennaji said tersely, unstrapping his flight harness.

“Aye, Captain.”

Karel’s voice sounded void of emotion. As if the big man had gone numb.

Gennaji glanced over at his new navigator. It looked as if the man hadn’t slept at all since they left Ceres. Since their failure. Since Andrej betrayed him.

He couldn’t help himself. 

“Pining for that backstabbing vybliadok?”

Karel shot him a glare that Gennaji could not back down from. He planted his magboots firmly down on the control room deck and returned the glare. Neither spoke for a moment.

“He made his choice,” Karel finally said. He kept his eyes firmly on his captain.

“Yes,” Gennaji said, crossing his arms. “He did. And you?”

No response.

“You agreed to join this crew. Standard sixteen-month contract.”

“For two more weeks.”

“Yes, two more weeks! A man makes a promise, a man keeps it. You have a problem with being a man?”

Karel turned red, clenched his fists. 

“Captain,” said the pilot. “The Lunar skiff is changing course. Heading…directly at us!”

“What?” Gennaji took a step towards Orynko. He felt a big hand grab the back of his right upper arm, twisted him around to face behind him. The punch came in slightly off target, a glancing blow on the chin that sent him backward a step or two. He staggered, recovered, anticipated the left body blow and blocked with the inner part of his right arm. Karel fell forward, his momentum carrying him into his captain.

Gennaji immediately sidestepped, tripping the bigger man and forcing him into a headlock from behind. Left forearm under the man’s left shoulder and neck, right arm behind and locked with the left bicep. Twisted hips, pushed down to the floor, pinning his opponent down with his body weight.

Karel gasped, grabbed at the forearm, kicking futilely.
