Reply to comment by SwiftTime00 in SpaceX on Twitter: Super Heavy Booster 7 completed a full duration static fire test of 31 Raptor engines, producing 7.9 million lbf of thrust (~3,600 metric tons) – less than half of the booster’s capability by allforspace
the naming scheme is a bit odd, the full stack is called starship and the upper stage is also called starship.

nasaspaceflight (not part of nasa) has permanent streams of starbase operations, and cape operations. I am sure lap padre will also livestream it.
Keep in mind that falcon heavy uses 27 engines at the same time (+1 on the upper stage).

that said you probably won't exert yourself as much when sleeping as you do when actively moving around and sweating.

one of the main issue is that air launching requires a lot of the rocket you are launching to be protection from the different stresses (in terms of direction) of flight.
It might turn out that we can do better but currently airlaunched rockets are inferior to ground launched rockets.

This one involves Isaacman/Polaris right? It makes sense if you want to start training private astronauts to start with a customer who knows how to do it and can transfer you the required knowledge.

a nuclear war would not really destroy the planet, not any more than cyanobacteria did.

starlink can only service a set amount of people (or if you want to be pedantic a certain bandwithd) per cell.

I wonder if falcon heavy and the larger fairing are still a plan. Obviously the company is pretty set on making starship the focus, but I still hope they are doing at least some hedgeing.

This whole deal was interesting because his relations with russia are horrible. He tried to buy refurbished ICBMs from them before founding SpaceX, they insulted him and raised prices. He then went to basically eat Roscosmos' Market share and they criminalized owning a Starlink dish in Russia.
so generally relations are not great.
