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
Kinda not against
Critical support for pig on pig violence
It would probably offset the issues he has had with his approval ratings because of this Epstein stuff
literal humiliation ritual for NASA libs
Vlog bothers in shambles
USA really responding to the climate crisis with “lalalalala I can’t hear you”
If you don’t test for Covid, nobody will have Covid.
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.
It would be cool if a scientist defected with the control codes^[How would you commandeer a satellite, exactly? Do those things run sshd? Everything is computer, right? I'm going to ask for detailed instructions in a FOIA request.] instead of pressing the self-destruct button.
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.
Look up RTEMS and VxWorks if you're curious
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?
Incredible.
I remember reading an article saying the rich generally believes in climate change but would rather ride it out than take any action
“Communism is failure”
“But also capitalism is choosing human extinction but trust me, it’s worth it because the alternative doesn’t respect the heckin’ property rightserino!”
(cw: self-harm)
they did the same in slashing the deep sea biology research funding
Lol, lmao
It's too bad Dianne feinstien isn't alive to see this. She would love it
Trump heard about Kessler syndrome and got really, really worried about it.
Well clearly it's one of those Jewish space lasers
I know this question is moot but... Does the president have singular authority over which satellites we have out there? Like, presumably only NASA knows how to do stuff with these satellites, and Trump has no idea if they are actually up there or not... Can't they just do nothing?
he (like any head of state) has the only real authority of "is anyone going to stop me?" and "is someone going to follow this order?"
rules only exist so far as someone is willing and able to enforce them
Yeah but like Trump has no idea if a satellite is in the sky or not lol nor how to remove one. They could absolutely just be like "uh yeah it's gone now"
yes, that's part of "is someone going to follow this order?"
prior to now i would say i dont know. now i say he has the authority to do anything he wants since nobody will stop him
he could just start declaring shit illegal and who’s gonna tell him that’s now how it works? and good luck arguing that to the cops who would be tasked with enforcing his orders.
🇨🇳: thanks.
