Solving the wrong problem

Transmission losses on the way to the data centre are tiny compared to the power consumption within the data centre.

Australia's age of consent laws apply both within Australia and outside Australia. It doesn't matter where in the world (or off world!) the crime is committed, Australians can still be prosecuted. Even if local laws were not broken.

Stash or splash? Lawmakers ask NASA to find alternatives for International Space Station

Getting empty Starships to the ISS will be easy in due course. Adding large cargo doors should be possible. The ISS modules will fit inside Starhips with room to spare. A de-orbit burn is easy. The big question is whether a Starship can handle re-entry and landing while it has a heavy ISS module inside.

New carbon capture tech could save us from datacenter doom

Re: I don't see how this can ever be viable

A forest does store CO2. Individual trees die and release CO2, new trees grow in their place and absorb CO2. So long as the forest continues to be a forest its overall CO2 continues to be stored. Deforestation adds to overall atmospheric CO2, planting new forests has the opposite effect.

No Littering Allowed

Sometimes shit happens and you have to deal with it, shit happened and they are dealing with it.

What I *REALLY* hope is now the Chinese will start to take space debris seriously, and implement their own rules for things like de-orbiting spent stages and not blowing stuff up on purpose.

Aside from that, I'm really impressed with their progress, space is hard and they are going places.

It can be lifted by 4 big helicopters. Let's use 6 to be on the safe side. Lift it the 5 miles to the river and set it down on a barge. Use the helicopters again at the destination.

Re: "can't put a Starship in orbit after 11 tries"

"Yes but the issue is the de-oorbit. SpaceX needs to demonstrate a reliable re-light of the engines on StarShip (really, really hate that name) to de-orbit it so it comes down where they need it to."

They have already demonstrated that, on both the most recent test flights. It landed on target both times, next to the bouy with the cameras. The last one even used its fins to curve around and completely change direction during the descent.

Almost flawless

That all went very well indeed!

I'm really looking forward to the 3rd generation testing, after one or two initial test flights they'll start catching things again and they'll go properly orbital.

Extra orbits are free, and don't change the risk.

Pick it up

What is the airspeed velocity of a Mil Mi-26 carrying a space shuttle? Obviously a helicopter couldn't lift a shuttle, even if gripping it by the husk. You'd actually need FOUR of those helicopters to lift it, and a bit of twine strung between them. At least they don't have to carry it far: the river is only about 5 miles to the north.

Re: as we don't know it

"Earth has also cycled the surface so many times that any signs from a billions years ago would have been wiped out."

The oldest intact rocks found so far on Earth's surface are more than 4 billion years old. And we've found plenty of rocks older than 3 billion years.

It happened early in Earth's history which suggests that it is actually likely, here and elsewhere.

Re: Should SpaceX test far more than putting a Starship in orbit?

It occurred to me that a landing-from-orbit could be done at Vandenberg, because the approach is over water. If it breaks up during re-entry the pieces end up in the Pacific, not all over Mexico or Florida.

Antimatter? It's way over there!

I always assumed the big bang flung matter and antimatter in opposite directions. The matter came this way and the antimatter went that way. The antimatter side of the universe would be equally as large as the matter side: symmetry. Pity we can never see far enough to see the antimatter side. I am not an astrophysicist, obviously!
