Bringer of Light first draft completed (finally!)

September 10, 2023

Way back in 2015, my good friend Rami Z Cohen came to me with an idea for a story. He had written two or three scenes about a group of asteroid hunters who stumbled upon something bizarre. The idea of mining asteroids was news at the time (and still is, although probably too expensive right now and not a worthwhile investment until we actually get some people in space who need metals without relying on NASA/ESA/JAXA/ISRO/etc).

I was more interested in philosophical aspects of finding that we are all (as the late great Carl Sagan loved to put it) “star stuff” (he meant carbon being created by supernovas, but we also know that asteroids are the way we got amino acids to rain down on ancient Earth).

So Rami and I began to email ideas back and forth for a few weeks, then we started to flesh out his characters and plot. I wrote a synopsis and outline and we hashed out the background.

Gateway not to be used until Artemis 4

ESA image. Gateway is planned to be much smaller and more cramped than ISS (about 1/6 the size).

NASA and its international partners see Gateway as a key platform to support the agency’s Artemis moon program and to build the technology required for future deep-space missions. Although the first elements of the small space station are expected to launch before the Artemis 3 mission lifts off in 2025 or 2026, NASA previously said that those astronauts will not use Gateway to “make that mission have a higher probability of success.”

While it’s a good idea to see some planning for this, I think maybe NASA should focus on getting Artemis 1 to work properly before they go on about Artemis 3 and 4.

Taking advantage of Gateway’s orbit far away from Earth’s protective magnetic field, three instruments will study risks due to radiation from the sun and from cosmic rays. Scientists hope this knowledge can help inform future long-term missions to the moon and Mars.

Since Gateway will orbit the Moon and not the Earth, the biggest problem will be preventing astronauts (and instruments!) from getting fried by solar radiation. Scientists need to come up with materials to shield people on Gateway and the Moon, or else we’re going nowhere…

(That said, regolith – soil, basically – has already been proposed and even tested: Llamas et al. (2022). “Effectiveness of Martian regolith as a radiation shield,” Planetary and Space Science, 218, 105517 https://www.sciencedirect.com/science/article/abs/pii/S0032063322001039)

And by the way, thanks for reading!

I’m sorry that I haven’t been posting much lately. Work has just become completely overwhelming, and the rainy season (here in Japan) hasn’t helped.

But I do read your comments and I appreciate them, and all your “likes,” too!

Just realized it’s been MONTHS since I posted the next installment of Bringer of Light.

Yikes.

Time to wrap up the first book and get to the climax already!

Artemis crew to be most diverse Moon crew

April 8, 2023
MThomas

The astronauts will be the first humans to fly in the vicinity of the moon in more than 50 years. They will also be the first to launch aboard NASA’s next-generation megarocket and Orion space capsule. The crew will not land on the moon but will swing around the celestial body, testing the performance of the Orion spacecraft, before returning to Earth.

They won’t land, only orbit. But a first is a first.

Let’s go to Mars, already.

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

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 😝

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.

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…
