Am tracking this down ... Super important to be fair. There are zero discounts even for family and friends.

Something messed up here. Tesla policy is equal pricing for all. No discounts ever unless a car is a floor model or was damaged.

@elonmusk How will occupants descend from the spacecraft?At 162 ft., appears too tall to utilize ladder w/ spacesuit. Especially repeatedly

Three cable elevator on a crane. Wind force on Mars is low, so don't need to worry about being blown around.

382s is with a 150 area ratio vacuum (or Mars ambient pressure) nozzle. Will go over specs for both versions on Tues.

@rocketrepreneur Meant to say 200 AR for production vac engine. Dev will be up to 150. Beyond that, too much flow separation in Earth atmos.

Once we accept self driving cars on the road, it's only a small step to allowing them to drive as fast as they deem safe for the conditions.

Sweet Jesus, that means you are pumping to 45-50 MPa... Surely this will be using multiple stage pumps?

Is that vacuum Isp for an upper-stage version? Because 380s vacuum Isp doesn't seem realistic for a booster version.

Production Raptor goal is specific impulse of 382 seconds and thrust of 3 MN (~310 metric tons) at 300 bar
Elon Musk
@elonmusk · Sep 26, 2016
Chamber pressure is almost 3X Merlin, so engine is about the same size for a given area ratio
