NEWS: OneWeb is joining SpaceX in the battle over using the 12GHz radio spectrum for 5G and satellite internet services.
OneWeb is working on a similar high-speed satellite internet service as SpaceX but on the enterprise side.

Charlie Ergen is trying steal the 12GHz band meant for space Internet. Not cool.

Did you know your @tesla is a gaming console? My kids love the amazing games on our Tesla. Tesla makes a phone on wheels that gets better overtime. @elonmusk

We’re making progress with Steam integration. Demo probably next month.

Elon Musk literally made the starship more pointy because of the movie "The Dictator" 🚀@elonmusk
Elon Musk
@elonmusk · Jul 15, 2022
Actually true. Then I suggested to the team that it didn’t need to be quite so pointy, since that’s just based on a movie joke, but everyone likes it pointy, so we kept it that way.

Elon, What do you think is the estimated timeframe for creating a self-sustaining civilization on Mars? 20 years? Self-sustaining meaning not relying/dependant on Earth for supplies
Elon Musk
@elonmusk · Jul 15, 2022
20 to 30 years from first human landing if launch rate growth is exponential.
Assumes transferring ~100k each rendezvous and ~1M total people needed.

Temperatures on Mars average about -81 degrees F. However, temperatures range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. So… seriously what the hell do you do when you get there ?

Removing shrouds will result in huge weight decrease. That's a big step up. However, Elon apart from the heat do you think that the engines & the secondary structure needs some sort of protection? Let's say from dust, debris, or unwanted objects?
Elon Musk
@elonmusk · Jul 15, 2022
Some small tubes & wiring need to be nested in a bigger tube for thermal protection, kinda like conduit in a house.
Engines themselves & booster base are extremely robust. High strength stainless steel is bulletproof to a handgun at ~2.5mm thickness. Booster dome is 4mm.

So is the electrical power for that coming from batteries? Have you done the trades on a generator on the turbo pump shaft vs battery?
Elon Musk
@elonmusk · Jul 15, 2022
Electric power for booster & ship is needed even when engines aren’t running & incremental power draw of TVC isn’t too bad. We have local supercaps on each engine to deal with power spikes.

All mass necessitated by an engine design should count as engine mass, eg shrouds, TVC hydraulic power or excess purge gas.
Raptors in production now have electric TVC, saving over a ton of hydraulics mass on booster.
Elon Musk
@elonmusk · Jul 15, 2022
Enabling engines to take the heat without shrouds might save over 10 tons, all things considered.
Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb.
Booster is purging all 33 engine shrouds in flight to prevent this.
