Look up Ham the Space Chimp, he went to orbit and back then they gave him a parade.

It should, probably nice and scorchy by now.

Data centers in space. Like what Microsoft is doing with that underwater data center.

Netflix could ship a bunch of SSDs into orbit.

Sounds pretty effin stupid. Google datacenter here is great because they take the cooling water from a river and collect the heat and use it to warm up houses.

They just let hard drive fail. They said it was more reliable than human data centers.

It would probably be good move for reducing launch costs due to demand.

they repaint / clean all the dirt off for new launch right? Also I imagine there would be legal issues if they left the logo own for a non-nasa launch

>> No.12131885

>>12131877
Nope; also the Koreans didn’t seem to care about the NASA logo.
The dirt and stuff is actually scorch marks, mostly. They leave it all on. Hell the stages don’t even get shipped back to CA after a flight - they just keep em in a warehouse at the cape

>> No.12131890

>>12131877
Why? It's their booster. They do whatever the fuck they want to do with it. NASA rented it from them for the DM-2 launch and that's that. Why the fuck would they repaint a booster?
It flew the ANASIS-II mission with the worm logo on it.

>> No.12131906

Are there any unofficial streams that are worth my time?

>> No.12131910

>>12131890
if they've already done it then I guess it's fine, but typically compnaies are super protective of their logos so as to not be associated with things they don't approve of or have people coming to them with questions over things they aren't in charge of. Though I looked it up and it seems anybody can use the nasa logos for just about anything? probably cus government I guess?

>> No.12131912

FUUUUUUUUUUUUUUUUUCK. SCRUBBED

>>12131910
If the commercial crew program had been a typical old school NASA program where they bought rockets cost plus, then it would have been different.
As it stands, they're just renting them so they have no say over what SpaceX does to their hardware afterwards.
