“@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!”

“@nntaleb Just saw this today. Tesla refunds in general should be easy to get electronically & certainly through customer service. Will he addressed.”
“@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.”
“@Neuro_Skeptic One person’s MRI machine is another’s railgun! Made a primitive one when I was studying physics at Penn. Hard to wield though.”
“@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.”

“@rhoehn @Tesla Thanks for mentioning! We should’ve done this ages ago.”
“@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!”

“@flcnhvy @Erdayastronaut @BocaChicaGal @NASASpaceflight Yes”
“@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.”

“@BnOrdhaug @Erdayastronaut I haven’t cross-checked RCS pulses with the MLI dimpling on the video, but it’s most likely the cause”
“@webtekno Nice 🤣🤣”
“@Erdayastronaut Since there’s only one main engine, which gives pitch and yaw control, roll control is provided by the nitrogen attitude control thrusters”
“@annerajb @waitbutwhy Looks like a thin, flat, round UFO on a stick. Starlink Terminal has motors to self-adjust optimal angle to view sky. Instructions are simply: - Plug in socket - Point at sky These instructions work in either order. No training required.”
