  • Honestly, I don’t think this could have gone any other way. As the article says, this is the so-called “Lane 1” missions which, while they’re less important and less heavy than “Lane 2” missions, are perfectly suited to the Falcon 9, or heavy if needed. There’s no need to get a heavy rocket like Vulcan involved, especially since it’s not proven yet, so the only reason I could think of for someone else winning would essentially be as a subsidy to help SpaceX’s competition. Once Vulcan has a couple dozen successful missions under its belt I’ll expect it to be more competitive.





  • I’d be interested in setting up the highest quality models to run locally, and I don’t have the budget for a GPU with anywhere near enough VRAM, but my main server PC has a 7900x and I could afford to upgrade its RAM - is it possible, and if so how difficult, to get this stuff running on CPU? Inference speed isn’t a sticking point as long as it’s not unusably slow, but I do have access to an OpenAI subscription so there just wouldn’t be much point with lower quality models except as a toy.





  • Kessler syndrome isn’t really that much of a risk specifically with Starlink (for now at least), as SpaceX seems to be doing things right despite Musk. They’re in such low orbits that even with a catastrophic loss of control, they’ll deorbit very quickly. The real risk comes as more companies and countries try to get a piece of the megaconstellation pie. Starlink in its own seems to be fairly safe and sustainable on its own, but that may quickly change when communication for collision avoidance maneuvers needs to be international.

    Despite Musk’s well-earned reputation for being a shithead, SpaceX has this far been doing the right thing far more often than most other space companies, and while it’s certainly possible that will change, the Starlink constellation will entirely disappear very quickly without constant replenishment, so it’s not as if we’d have no chance to act if they begin to show signs of concerning behavior. What’s far more worrying to me in terms of Kessler syndrome is the recent escalation around space warfare, as tensions between Russia, China, and the US continue to boil and nobody seems willing to really commit to making space a neutral zone. Even with space historically being an area of strong international cooperation despite politics (just look at the ISS), that unfortunately seems to be rapidly changing.
