@SPEXcast @McMurchie @Robotbeat @John_Gardi @SpaceX Just planning on keeping the public informed about progress & setbacks. Will be some RUDs along the way, but excitement is guaranteed!

@McMurchie @SPEXcast @Robotbeat @John_Gardi @SpaceX The goodwill of the public is critical to Starship’s success

@epoxy101 @Robotbeat @John_Gardi @SpaceX At least 10X cheaper

@SPEXcast @Robotbeat @John_Gardi @SpaceX Very dependent on volume, but I’m confident moving to Mars (return ticket is free) will one day cost less than $500k & maybe even below $100k. Low enough that most people in advanced economies could sell their home on Earth & move to Mars if they want.

@SpaceXFan97 @Robotbeat @John_Gardi @SpaceX Yes

@Robotbeat @John_Gardi @SpaceX This will sound implausible, but I think there’s a path to build Starship / Super Heavy for less than Falcon 9

@John_Gardi @SpaceX But not an extendable nozzle though, as that just saves length. Nozzle diameter is limited by body diameter.

@SpaceXFan97 @alexmd2 @SpaceX Much above 300 bar main chamber pressure means extreme oxygen preburner pressure of 700 to 800+ bar. Definitely pushing the limit of known physics.

@_cgp @SpaceX Propellant was not deep cryo. CH4 & O2 were just barely below liquid temp at 1 bar. In theory, Raptor should do ~300 bar at deep cryo, provided everything holds together, which is far from certain. However, only 250 bar is needed for nominal operation of Starship/Super Heavy.

@John_Gardi @SpaceX Yes, aiming for 380 sec Isp with vac nozzle. Maybe 382 if we get lucky.

@13ericralph31 @SpaceX I think 6 where we lit main chamber & several with only preburners

@alexmd2 @SpaceX Definitely! It’s amazing that the RD-170 & RD-180 engines held the record for so many decades. Excellent engineering.

Raptor reached 268.9 bar today, exceeding prior record held by the awesome Russian RD-180. Great work by @SpaceX engine/test team! https://t.co/yPrvO0JhyY

Just left Zeebrugge, now Tilburg, then Tesla HQ in Amsterdam & Oslo tonight to review service in Norway. Exciting to see thousands of Model 3’s on their way to owners in Europe! https://t.co/PeRo4jhiCB
