China investigating how to build a mega spaceship

January 9, 2022

“China is investigating how to build ultra-large spacecraft that are up to 0.6 mile (1 kilometer) long. But how feasible is the idea, and what would be the use of such a massive spacecraft?“
https://www.livescience.com/mega-spaceship-china-proposal.html

The original title of the Live Science post linked above is “China wants to build…” but this is incorrect. The National Natural Science Foundation of China is proposing a feasibility study. This is not the same thing as “China wants to build a kilometer-long ship.”

Likely the study will find out that it’s just too expensive and not worth it in terms of effort, resources, and maintenance costs. But it may show the benefits of setting up a base on the Moon and then sending materials there to be 3D-printed for future exploration or human colonies elsewhere.

Sending up a ginormous ship from Earth is foolhardy. Figuring out how to build stuff in space is much smarter.

World’s largest space telescope has liftoff

The James Webb Space Telescope – Hubble’s successor – has successfully lifted off.

Now starts the “two weeks of terror” as it gets into position and unfolds. Fingers crossed! 🤞

Trace Gas Orbiter finds traces of hydrogen underground in the Valles Marineris

The original article title?

“Astronomers Detect Secret Water Reserves in The Largest Canyon in The Solar System”

Science isn’t quite as catchy. The hydrogen may indicate water in the form of permafrost 3 feet and more under the surface.

The high-hydrogen region is about the size of the Netherlands, and overlaps with Candor Chasma, one of the largest canyons in the Valles Marineris system.

Looks like there may be some competition for who gets to land near here first…

Water Bears in Space! Uh. Again.

Hang on, I think I’ve seen this before…

Oh.

Not such a great idea, then, to send them on an interstellar cruise…

AstroCrete…a “blood-curdling” building technique for Mars

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…

Destination: Red Planet

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.

Squids…In…Space….!

OK, yeah, squid doesn’t have a plural, but come on, can’t you just hear “Miss Squiddy”? 🦑 (Reference lost on younger viewers.)

The 128 baby bobtail squid will be used as part of research into the effects of spaceflight on beneficial interactions between microbes and animals.
https://www.bbc.com/news/science-environment-57339989

So why use squid instead of dogs, chimps, or other mammals?

The squid have an immune system which is similar to that of humans.

Ah.

And their distinct lack of a spine makes them similar to most politicians, too. Very helpful for finding out what might happen if we decide to…

Nah.

X-Rays from Uranus!

The gag practically writes itself…

…but seriously, this is neat. One source of the X-Rays is the Sun (it also bounces off of Jupiter and Saturn). But there may be yet another source…perhaps the rings of Uranus or the planet itself.

And no, it’s not really pink. That’s just a Chandra X-ray image.

Shame, really.

Maybe there is Hope, after all

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.
