One is attached to the International Space Station, and the other is collecting data as a stand-alone satellite. The latter would meet its permanent demise after burning up in the atmosphere if the mission were to be terminated.
A 2023 review by NASA concluded that the data they’d been providing had been “of exceptionally high quality.”
The observatories provide detailed carbon dioxide measurements across various locations, allowing scientists to get a detailed glimpse of how human activity is affecting greenhouse gas emissions.
(Ex NASA employee) David Crisp said it “makes no economic sense to terminate NASA missions that are returning incredibly valuable data,” pointing out it costs only $15 million per year to maintain both observatories, a tiny fraction of the agency’s $25.4 billion budget.
Watching a world superpower destroy itself in real time is both fascinating and horrifying
Guess you know how the Soviets felt now.
Looking forward to Trump shelling Congress after the midterms
It would probably offset the issues he has had with his approval ratings because of this Epstein stuff
Critical support for pig on pig violence
Kinda not against
If you don’t test for Covid, nobody will have Covid.
literal humiliation ritual for NASA libs
Vlog bothers in shambles
This is actually kinda surprising. Having high quality climate change data while also barreling full-speed down the path towards total death seems like it’d be the best move to maximize misery.
i can confirm that stuff like ssh sometimes sees use to configure some systems of satellite

That’s so cool. What I love about learning Linux is the applications are endless—practically every embedded device uses some form of it (including NASA satellites, I presume).
it depends, cuz linux is a bit expensive and had trouble doing some realtime os stuff. this is what ive heard from coworkers though, so take that with a grain of salt.
Probably still something Unix-like?
It’s usually a stripped down version of the Linux kernel. See my post above where some cube sats use the kernel as an x86 bootloader.
They probably just fork BusyBox for most stuff, then strip it even more if they need to. Honestly just doing development with podman/docker targeting your architecture is the most obvious solution. Especially since you can adjust your environment or target multiple different possibile architectures (assuming the board itself is built by a contractor) without too much headache.
One of the interesting things about the rapidly-improving RISC-V architecture is that NASA has decided to standardize on it for future in-space systems. Of course who knows when or if that’s going to happen now of course.
That’s actually really sick. Makes sense too since RISC-V can be super power efficient and it’s much easier to compile for. I’d guess that even as they get their budget cut, that part will remain operational. Too many private companies that will want to switch to RISC-V and will want to be able to just crib the tooling from a government agency.

This is indeed what I wanted to know. Thank you.
They at least use parts of the kernel or tooling that they strip out and re-compile for their specific systems.
I know that the computers in some of these satellites use super custom hardware, and Linux can be compiled to run on basically anything. Here’s a spec that explicitly uses the kernel on nano sats
That one doesn’t use
sshd, but it does use UDP and an internal Ethernet switch to orchestrate all the components and communicate with the ground using some combo of radio bands as serial interfaces.In that case, of you knew the codes you could gain control of it using a big enough ham radio lol
They do also tend to transmit the data unencrypted (for civilian weather and such) so if you can tune into the sat, you could pull images with one of the highest pings imaginable
In that case, of you knew the codes you could gain control of it using a big enough ham radio lol
Idea for a movie!
There’s gotta be a way to give it to China, right?
USA really responding to the climate crisis with “lalalalala I can’t hear you”
(cw: self-harm)
Incredible.
Lol, lmao
I remember reading an article saying the rich generally believes in climate change but would rather ride it out than take any action
they did the same in slashing the deep sea biology research funding
Well clearly it’s one of those Jewish space lasers
