@GhostOnTheHalfShell @sundogplanets Goldfinger remains the quintessential Bond film. And it always will be.
If I recall correctly, at least for Sean Connery Thunderball was his personal favorite film.
It has been so long since I’ve watched any of these films. I really should again. I’ve had some fun watching thin man. I really appreciate most the first two movies.
-
@faithisleaping @sundogplanets I brought the same thing up to some friends. They were like there are other ways to build in redundancy and besides the output isn't critical anyway.
I'm like... Cool so we're just going to have transistors randomly turning on causing shoot through. What could go wrong.
@fullywoolly @faithisleaping @sundogplanets stochastic parrot is extra stochastic today.

@sundogplanets Sorry, that's probably not fair to dogs.
@ScottMGS @sundogplanets as a dog, no it's not lmao

After modelling this in detail, I can say that that these companies can't even do basic geometry, apparently. They want tens of thousands of satellites to have 24 hour sunlight, so sun-synchronous terminator orbits, baybeeee!
But as Hugh Lewis pointed out (I know, ew, linkedin sorry) https://www.linkedin.com/pulse/sun-always-shines-tv-hugh-lewis-tlkbe/ IT DOESN'T FUCKING WORK unless you're above 1400km altitude. And then you're not in the *magical* low-latency low-altitude zone that these companies actually want for fast comms.
@sundogplanets
I had naively assumed that sun-synchronous orbits were perpendicular to the ecliptic, not the equator. Presumably such orbits don't benefit from the same rotation that keeps them facing the Sun? -

@GhostOnTheHalfShell @sundogplanets And he did it twice, too.

@sundogplanets This is so colossally stupid. Like, I know AI + Space! is a perfect VC honeypot but has anyone even thought about the fact that GPUs go out of date inside like 2-3 years? Are they really planning to launch 10,000 satellites per year indefinitely?
Also, has anyone given ANY thought to radiation hardening? GPUs of the sort that people are using for AI are typically manufactured on a 3nm process or so. Most orbital hardware which we actually want to keep running is manufactured on like 50nm because radiation absolutely destroys tiny circuits.
But I'm sure it'll be fine...
@faithisleaping @sundogplanets
… has anyone heard an explanation of how these satellites will shed their waste heat?The more I hear/think about the problems, the more convinced I am that (actually deploying orbital data centers) is not the actual point of these filings.

@Red_Shirt_no2 The pictures in the marketing material show radiators. Are they enough? Probably not. Do they know that? Of course not!

@Red_Shirt_no2 I think a lot of these muppets are under the impression that space is cold. I don't think they have any idea just how hard it is to shed waist heat.

And then there's a whole section where they say that the FCC isn't allowed to consider environmental regulations, and they point to Reflect Orbital getting approved where the FCC specifically said they're not allowed to consider anything except radio broadcasts. This section might actually make me cry.
Next section is just... complaining, I think?
And then they end with saying that clearly they need to be approved.
Fuck you, FCC. Kessler Syndrome is on you.
@sundogplanets it's really a question if you can hope physics stops them before or after they do unfixable damage to the orbit.
-
Apparently ALL the opposition letters mentioned how 20,000 bright satellites would absolutely destroy astronomy, so that's nice.
Ok, well, this section is 100% gaslighting, which I expected. "No no no, radio astronomers, you are overreacting! We will totally not clobber your bands and we magically don't have harmonics or unintended radio emissions, despite not having actually ever built a satellite before. Also we'll use lasers to fix everything. Radio astronomers, shut up."
@sundogplanets Did anybody mention the risk of evil space aliens seeing the shiny ring around our planet and enacting a programme to darken the overly lit forest?
-
Sure, completely untested, brand-fucking-new company that has never built or launched a satellite. You can definitely launch 20,000 of the biggest satellites ever built.
Oh apparently their first demo mission is scheduled for OCTOBER 2026? Gosh these guys are fucking unreal. The mission is listed as "power beaming demonstration"
What does that even fucking mean? Guess they're going to fry some birds and maybe some pilots? Hm. Watch for that I guess.
This just really highlights the freaking audacity of greedy DOGE Bros:
Speculative.
Arrogantly wrong about everything.
Lazily entitled to money that isn't theirs.
Apathetic to consequences. -
WOW it gets even more whimsical and hand-wavy in the orbital debris section. Actual quote: "Certain commenters raise concerns regarding the extent of the orbital debris mitigation information provided in the application but ignore Cowboy Space’s steadfast commitment to operating
safely."In other words: "Why won't scientists believe the words that we wrote down without any actual data, information, citations, or sketches?"
@sundogplanets Oh, a "steadfast commitment to operating safely"? Why didn't you say so earlier? That changes everything.
-
@sundogplanets I note that in my engineering job, we call people "cowboys" as a pejorative, to describe someone who hasn't done solid calculations and is making decisions based on vibes
Yep. That's the meaning I'm used to. But since they seem to turn other meanings around as well (Tolkien, Cyberpunk,...) I assume they see themselves as bold nonconformists when they use the word.
-
The rest of the astronomy section is pure bullshit, unadulterated by any facts or actual information.
"We will definitely work with astronomers, and we definitely won't have any reflections because our satellites are magical, we also won't have any infrared emissions, even though physics says that very hot things emit blackbody radiation. We are cowboys, not bound by mere LAWS OF PHYSICS."
-
Cowboy Space (I hate their name so much) published their consolidated response a week ago but we just noticed it. EDIT: It was due at 5pm EDT today. So... I guess I have to read this shit. Swearing a lot here will get me through it.
A reminder: this is the 4th company that wants to launch fucking enormous "AI data center" satellites into sun-synchronous terminator orbits, giving Earth a ring. This particular company wants 20,000 satellites in one ring.
@sundogplanets so apropos of nothing I'm now raising Pre-seed for my own space startup, it's an orbital demolitions service. I have this intuition that there'll be a big demand for this, just a crazy hunch.

@faithisleaping @sundogplanets this reminds me of when I used to work with satellite transmission - 3/4 of the signal was essentially error correct. The radiation aspect was pricing. The signal transponders degraded over time (due to basically being bombarded by radiation every day) so you moved from one to another over time. Depending on your fees determined if/when you did this.

@sundogplanets Admittedly I don't know much about astronomy but I know a shit ton about data centers and server infrastructure, and this _has_ to be a grift of some kind.
Compute is nowhere near reliable enough to be thrown into orbit for 18+ months without something failing: a fan, a heat sink, a power supply, a DIMM, what have you—that kind of shit breaks DAILY once you get above a certain quantity of systems, and it's pure fiction to think you could just strand it all in space and expect nothing to go bad—even the very reliable enterprise-grade stuff is not reliable enough to be left unmaintained indefinitely.
And that doesn't even touch the stupidly complex problem of cooling high density, high power compute in a vacuum (which I assume their white paper just winks at) ... and the gobshites at the FCC won't push back on any of this, probably because they'll want to cash in on the scam, too.

@ScottMGS exactly. Dogs are social animals. @sundogplanets
@NatureMC @ScottMGS @sundogplanets People LIKE dogs.

@faithisleaping @sundogplanets GPUs also often wear out inside of months, or fail spontaneously, or are installed in systems that fail spontaneously, because compute hardware is just not built to last like this.

@klausfiend Thanks for sharing this. And yeah, they said absolutely nothing at all in any of the documents about how this would actually WORK.
