Does anyone know a good broad book on physiological barriers to human spaceflight which focuses on the science and engineering not on arguing against crewed spacetravel?
The one by the Weinersmiths is supposed to be snarky commedy, I don't remember Mary Roach being interested in things like degenerative eye problems or filtering water or keeping moon dust out of the habitat. Digging up individual papers without an overview feels like a deep and confusing rabbit hole. #space #boostsAppreciated
No new info on the status of the Voyager 1 spacecraft, which since Sep 2023 has been sending a 1010 bit pattern instead of real data.
Several popular science outfits have been covering it lately. A bit flip in the FDS is suspected, but it is difficult to identify since the memory cannot be read back.
Several commands were sent yesterday to Voyager 1; responses will arrive 45 hours later tomorrow.
Wonder why they cannot overwrite all prog and data memory.

I don't do new year's resolutions, but all the same it's as good a time as any to change something, or start something, or renew something. I'd like to do more writing this year, but I want it to be useful for some subset of people rather than just an outlet for me.
So...
1. If you consider yourself to be a "not-maths" person in some way (or lack confidence, or struggle(d) with it), I'd like to answer any #maths-themed questions that you have. I'm not talking homework or exam questions. I'm thinking your personal queries _about_ maths more generally. Stuff like "what does nth mean?", or anything else that you may be wondering. I occasionally post maths stuff at http://tommaths.blogspot.com .
2. If you've got a burning question about #space, Blogstronomy still exists, though it's been very quiet for a while now. Maybe drop me a line and ask your question? (You can check I haven't already answered it here: https://blogstronomy.blogspot.com)
3. If you think I might be able to write about something mathsy for your blog, website, publication (or museum exhibition) I'm totally up for that even (especially?) if you think there's no way maths could fit with what you do. I tend to link to external work I've done here: https://tkbriggs.co.uk/topics/portfolio/ (though it does need updating).
How Long Does it Take the Moon to Orbit the Earth?
Question posed by Elly. The Moon is a popular subject on Blogstronomy so I was surprised to find that this question hadn't been covered ...TeaKayB (Blogger)
Phew! Thanks to new data from ESO's Very Large #Telescope, we now know that a white dwarf that was set for a close encounter with our Solar System in 29000 years isn't actually headed our way. Turns out that the intense magnetic field of the #star had biased the previous measurements of the approach speed. You're welcome everyone! 😉

Galactic collisions result in a billion-year gravitational dance, as shown in this captivating supercomputer simulation. The simulation depicts the collision of two spiral galaxies and is complemented by actual images of galactic collisions at various stages captured by Hubble.

Was the SpaceX Starship’s launch a failure or a success?
Ars Technica says "For those who know a bit more about the launch industry and the iterative design methodology, getting the Super Heavy rocket and Starship upper stage off the launch pad was a huge success." The company's development process is messier, but it's also much faster, says author Eric Berger.
So what was that? Was Starship’s launch a failure or a success?
