It also means not paying credit card fees, not having to chase down bounced checks, etc. Cash means the money is there, which has value.

It's the same sort of people that think they're making art when they take a photograph with their iPhone.

How are you going to suffocate when the thrusters are sending out compressed air?

Except the point of the original post is that has changed.

While I'd suspect the design is still in flux, the current design is for a 120kw satellite with 110 square meters of radiators. Scaling to hundreds of gigawatts is intended to be by repeatedly launching smaller designs.

Offhand, do you know what format that data is in? Is it a question and then a human answering that question? Mostly just curious at to what the training data consists of.

I suspect that this is the start of a play for SpaceX's orbital datacenter project - if they're really planning on launching as many satellites as they've said (and Starship is going to massively lower the cost of launch), they won't be able to fill them with Grok. So perhaps it's best to become the infrastructure provider to the other AI Labs.

After the accident, Apollo 13 had 4 burns.

The DPS-1 burn which restored the free return trajectory was done using the Apollo guidance computer.

The PC+2 burn which sped up the return from earth was done using the Apollo guidance computer.

The MCC-5 mid-course correction burn was done by hand.

The MCC-7 mid-course correction burn was done by hand, but used the Apollo guidance computer to integrate the accelerometer to let everyone know when the burn was done.

(All the burns on Apollo 8 were computer controlled. I'd assume Gemini 7 and 12 were hand flown, though I don't know for sure.)

So, that's generally not something local governments do in the US. They do things like increasing taxes on data centers, denying water rights, electric interconnection rights, etc. (At least, all of this has been threatened against data centers.)

SpaceX's launch capacity is an order of magnitude larger that all four of those put together.

It's putting AI processing out of the reach of hostile local, state, and international governments. Does it need to be a cover?

This is a really good point, especially since a similar plan was attempted once before and failed.

That was a great article.

Adding to it - Apollo 13 was a mission where 3 men should have died, but somehow didn't. If it had happened while the LM was on the moon, you would have had the CSM lose power, and then two men on the moon would have had no way to return home.

(And for the shuttle design mission - my understanding is it was likely the ability to do a HEXAGON-style film return mission in a single orbit, before the Soviets knew what was happeneing.)

This is about to change.

New NASA administrator Isaacman has redone the Artemis program. The changes were announced at the Ignition event a few weeks ago:

If you read one thing, read the sides on building the moon base:

The goals it to fly often - adding a SLS launch to 2027 and a second launch to 2028. This drops the cost-per-launch, which is mostly fixed. It redoes SLS to make it less expensive and more capable. It moves the lunar space station down to the surface of the moon.

And it's budgeted at $10B/3 years, which fits into NASA's budget.

Isaacman took the Artemis program and fixed it. The reckoning came, and it's looking good.
