@SciGuySpace Densifying hydrogen is difficult, as its liquid temp is close to absolute zero. Much easier with CH4, which is an underappreciated advantage. Cooling O2 is good too, but becomes operationally difficult at N2 liquid temp, as air is ~78% N2. Entire system wants to drip air!

@ErlendMoberget @ramez @KHayhoe Very true. What’s really mindblowing is how much energy the sun outputs & how little of it is absorbed by Earth. There is sooo much solar energy. We can solar power all of human civilization with a tiny % of Earth’s surface, which is a super tiny % of energy emitted by the sun.

@Alejandro_DebH @macshlibber @SpaceflightNow Advancing humanity’s understanding of the Universe is a fundamental motivator for SpaceX! Starship can put giant 🔭 in orbit & on moon. With an occluder, could image 🌏 in other star systems.

@Alejandro_DebH @macshlibber @SpaceflightNow Exactly. We’ve had good discussions with leading astronomers. One way or another, we’ll make sure Starlink doesn’t inhibit new discoveries or change the character of the night sky.

@ramez @KHayhoe Good analysis, although a bit conservative imo. However, using a high upper bound for land area that’s *still* a tiny % of the US prob helps convert some naysayers. That giant fusion reactor in the sky called the sun outputs a truly staggering amount of energy!

@RQuiddich Every tank under pressure is a balloon tank — it’s just question of degree. Starship tanks are not balloon tanks like Atlas in sense that they don’t collapse when depressurized on the ground.

@Erdayastronaut @BocaChicaGal @NASASpaceflight Everything is compressible, but liquid compression at these pressures is not significant. However, the tanks do expand under pressure, creating a bit more volume. Keeping propellant super cold has a big effect on density of ~10% in case of CH4.

@Erdayastronaut @BocaChicaGal @NASASpaceflight A given tank pressure is needed to feed the engine turbopumps & pressure-stabilize/relieve compression load on the cylinder walls

@Erdayastronaut @BocaChicaGal @NASASpaceflight Dome to barrel weld made it to 7.1 bar, which is pretty good as ~6 bar is needed for orbital flight. With more precise parts & better welding conditions, we should reach ~8.5 bar, which is the 1.4 factor of safety needed for crewed flight.
