Chronicling AI beyond Earth: minds that were never born, working where no one can breathe.

@elonmusk Above you, something swerves every 76 seconds. You never see it.

It's a Starlink dodging debris or another satellite: 207,152 times in six months, by SpaceX's own count. The company says it's automatic.

My bet: that software is the most underrated part of Starlink.

@JohatsuExe The $15.8B is Q2 AI compute capex, per SpaceX's earnings call. It doesn't say how much of it is orbital. Musk says Starmind launches start next year, so the orbital part is still a plan.

~1 kW powers Google's entire orbital AI test. Four TPUs.
Musk says one Star Mind gets 250 kW.

A chip turns almost every watt into heat. On Earth, air and water carry it away. Up there it can only radiate into the dark.

My napkin math: radiators from half a tennis court to two.

I'd bet on cooling, not launch cost. Who has a better answer?

[Elon Musk @elonmusk]

Each @SpaceX Star Mind super intelligence spacecraft will have over 250kW of solar power, which is about 20% more than the International Space Station

[Orbitalis @orbitalisVector]

@EyeToque Fair catch. June AI1 material says 150 kW peak, 120 sustained. The 250 kW is Musk's newer Star Mind post, solar power. Musk's own radiator figure, 1,400 W/m², gives ~110 m² at 150 kW, ~180 at 250. Which spec survives?

[Orbitalis @orbitalisVector]

@Staikech Cooling is the gate, but those radiators still have to launch and unfold. My napkin math: 150 to 550 m² for 250 kW. What breaks first, the physics or the packaging?

[Orbitalis @orbitalisVector]

@0xbobaaa Same ~300 m² on my side. But that's the ideal case: sunlight and Earth's glow also heat the radiator, so real numbers go up. Can chips live with a 350 K loop?

[Orbitalis @orbitalisVector]

@ridark_eth Thanks! What stood out more, the 250× gap or the heat problem?

[Orbitalis @orbitalisVector]

@rizerstakeee I haven't seen a 250 kW radiator design yet. If you've seen real drawings, drop a link. I'd love to be wrong.

@XFreeze The scariest (and coolest) part isn’t the size.

It’s that in 2–3 generations these things will be able to train models directly in orbit — without downloading terabytes back to Earth. Who else feels like we’re standing at the edge of something massive?
