In theory, methalox can be distilled directly from Earth's atmosphere.

Peak oil won't be an issue.

Redpill me on replacing LOX with pressurized N2O as your oxidizer.

RP1 + N2O or C3H8 + N2O.

Boom, you have two fully storable, non toxic bipropellent blends.

How do you build self-recovering solid boosters?

Falcon-style retropopulsive landing is out of the question since, by design, SRB's can't be throttled.

Rockets are a scam anyway, they can only work in the athmosphere because in space they don't have anything to push against.

Complete baka here.

Give me the quick rundown on what Musk hopes to accomplish with these "flying grain silo" prototypes and their short test flights.

How far off are the serious prototypes?

Musk needs to take a trip up to the iss. I want to see the first twitter shit post from space.

A major obstacle to that is removing all the debris and abandoned satellites from above LEO, opening up HEO to large space stations that would be severely affected by aerodynamic drag at LEO.

If Boeing were smart they'd develop a "garbage truck" variant of the X-37 both for bringing derelict satellites back to Earth for scrapping and debris trawling missions where it deploys some kind of massive net from its payload bay that collects small fragments.

Eventually, the only debris in orbit would be tiny ice particles from rocket exhaust which gradually sublimate in sunlight.

Shooo ULA shill

Boeing gets cost plus contracts and still can't build a capsule.
