Hang on, I think I’ve seen this before…
Oh.
Not such a great idea, then, to send them on an interstellar cruise…
Water Bears in Space! Uh. Again.
November 12, 2021
Sigh.Way behind. Again.
September 18, 2021
OK, I readily admit that I am once again waaaay behind on my scifi blogging.
At some point last week, I looked up from the mass amounts of work I had left to do and went, “Uh. August 21st? Was that really the last time I posted?”
Uh. Yup.
😣
I’ll do my best to get the rest of Riss’s story online on a biweekly basis, like I promised I would.
But promises…
AstroCrete…a “blood-curdling” building technique for Mars
September 18, 2021
The blood, sweat, and tears of pioneering astronauts could literally turn Mars regolith into building materials.
First, however, they’d need to get the 3D printers there…
Mars has a really thick skin
July 28, 2021
Well, OK, technically it’s the mantle, not the crust.
But it is thick. Super thick. And no gradations like the Earth.
Extrapolating to the known surface geology of the rest of the planet, this suggests an average thickness of between 24km and 72km. By contrast, Earth’s average crustal thickness is 15-20km.

So what does this mean?
For one thing, it probably explains why there’s no breathable atmosphere on Mars.
Mars never developed a global magnetic field to block solar radiation. So it’s atmosphere was basically ripped right off.
And any terraforming attempts in the future would fail on a global scale. But maybe locally it might work…
Destination: Red Planet
June 27, 2021
Like other nations, China “regards Mars exploration as the preferred destination for deep space exploration,” Wang said.
https://abcnews.go.com/amp/Technology/china-unveils-ambitious-roadmap-human-mars-exploration/
China’s plan calls for setting up a permanently occupied base and a fleet of interplanetary craft. Probably it’s a good idea to first see whether it can meet its goal of landing people on Mars in 2033.
Of course, China is “willing to join hands with our counterparts and partners all over the world,” but it’s unlikely NASA, JAXA, ESA, and the UAE and other countries not named Russia will “cooperate.”
The next space race is here. Just wait until multinats actually decide asteroid mining is worth the risk and expense.
Ion engines are no longer sci-fi
June 19, 2021
The inclusion of an ion propulsion system in a long-running, Earth-orbiting space station will give researchers a chance to test out the tech while astronauts are still close to home — and if it works as hoped, it could one day ferry explorers to Mars and even more distant destinations.

That’s a big “if.”
Another is what the price will be, since no doubt this neat new tech won’t easily be shared among nation-states.
Just yesterday Chinese astronauts entered their new space station for the first time. They weren’t allowed into the ISS. Now they don’t need the ISS.
The old rivalries will follow humanity into space…but for how long will the rivalries remain…
“Wright Brothers’ moment” – helicopters on Mars
April 19, 2021
“We together flew on Mars. We together have our Wright brothers moment.”
https://www.washingtonpost.com/technology/2021/04/19/nasa-ingenuity-helicopter-mars/
Yeah, yeah, I know. Technically, a German immigrant in Connecticut flew a plane before Orville and Wilbur.
But PR counts. Kudos, NASA!
Still, they persevered!
February 18, 2021
Great job, NASA! Landing on Mars is always a tricky business.
Now all Perseverance has to do is find traces of life, save it without contamination, and then wait for another rocket, another rover, and a satellite to get in orbit so the samples can be sent back to Earth.
Piece of cake, right?

Maybe there is Hope, after all
February 10, 2021
Congratulations, UAE! The Hope Probe (al-Amal) successfully entered Mars orbit on February 9th.
Made in the US (Boulder, Colorado) and the United Arab Emirates (Dubai) and launched from Japan, it shows what hat can be accomplished through international cooperation instead of competition.
Maybe it is truly Hope, after all, and not just for Arab states.
Weebles wobble — and so does Mars
February 5, 2021
Looks like Mars doesn’t spin perfectly on its axis. In fact, it wobbles.
And no one knows why.
This makes Mars only the second planet in our solar system to exhibit what’s called the “Chandler wobble.”
The other planet?
Why, Earth, of course.
(And, no, nobody knows why. Hmm. Chandler?)
