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


This is the surface of a comet! Dust is swirling around the surface of Comet 67/P -- captured in 2016 by ESA's Rosetta spacecraft, processing by Jacint Roger Perez.

Still one of the most remarkable scenes in space exploration.

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.

🧑‍🔬 Frustrated by the constraints of Earth, a team of California scientists took tumor research to space—and may have discovered a ‘kill switch' for cancer

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).


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! 😉

We tell you everything in our latest ESO #blog: https://www.eso.org/public/blog/rogue-star/

If you were stargazing on Mars, you could watch the dance of the Earth & Moon in your evening sky. ESA's Mars Express just made a little sped-up movie of what you'd see. (Both Earth & Moon would be easily visible to the naked eye.) https://www.esa.int/Science_Exploration/Space_Science/Mars_Express/Earth_and_Moon_seen_from_Mars #science #space #astrodon

Mars - #HopeMarsMission spotted an elongated cloud around Ascraeus Mons

Timetag: 2021-07-10
Altitude: 33580 km
Raw Data from: https://sdc.emiratesmarsmission.a
Filters: f635+f546+f437 (f320UV used just to enhance a little bit the cloud around the Ascraeus Mons)

I love also Olympus and Arsia Mons on the Terminator!

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.

This is amazing. NASA commissioned a microgravity compatible espresso machine for the International Space Station (to make ISSpresso, obviously), and to stop the astronaut having to drink espresso from a closed container with a straw, a bunch of NASA volunteers designed the Space Cup, so the crema bubbles could be seen and the coffee smelled even in microgravity. And I've just been sent one in the post. That's Samantha Cristoforetti drinking from it in the ISS cupola. #ISS #Space #Coffee


Gorgeous: En route to lunar orbit, South Korea's Danuri spacecraft captured this sequence of the Moon transiting in front of the Earth. https://www.kari.re.kr/eng/kariimg/list.do?img_gbn=PHO&img_tp=S&mno=sub04_01&listType=3&img_thema_cd=%EB%8B%AC%ED%83%90%EC%82%AC #Moon #space #KARI


My daughter asked me, "Have we ever seen a star being born?" Here's part of the answer.
Deep within interstellar cloud CB 130-3, a dense knot of gas and dust teeters on the edge of collapse. When it goes, it will become a new star.

The view from NASA's Artemis mission yesterday is just...words fail me.

HT @JPMajor@twitter.com and the brilliant engineers & scientists who made this happen.

There is a certain beauty in when this happens. The geometry of the mutual event, eclipse, conjunction, whatever you want to call it. It's just... 🤷 😭

“The Outer Space Treaty of 1967 created an obligation under international law to avoid the harmful contamination of outer space, the moon and other celestial bodies…”

Meanwhile, Elon Musk: “oi, I’ve got an idea, why don’t I launch my fucking car into space for shits, giggles, and PR?”

Everyone: “ooh, he’s so smart, he will save us all”
