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), th

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.

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 dat

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 wou

They just set the record for being farther away from Earth than anyone else. The commander just named a feature on the moon for his late wife.

We're about to find out. The new NASA administrator, Isaacman, seems to have done a very good job of convincing the various Senators to, if not get rid of the pork, allow him to allocate it in a way that benefits the lunar program. Th

Successful space travel is one of the few big news events where nobody has to be unhappy. Most of the other big news events are ones where people get severely hurt, and political ones where one partly loses. With this, we can look up at the

This is a perfect way to put it. Artemis II is not safe, at least by the standards we apply to things. It's the third flight of a capsule, on the second flight of the rocket, and the first flight of things like the life support system.

Interest also compensates for the other things that money could be doing. If I didn't loan it to you (or a student), then I would be doing something else with the money, even if just buying a government bond.

The point of the Starship program is to drop the cost of a kg going to space significantly - this isn't meant to be launched with rockets that aren't fully reusable.
