Elon, have you used the "planisher" on the SN4 welds yet?

Are you designing the manufacturing system in tandem w the test vehicles or will you need to wait to perfect the vehicle first?
Elon Musk
@elonmusk · Apr 26, 2020
Successive iteration of both design & manufacturing. Latter is 1000% harder than former.

Fingers and toes crossed for Starship SN4 tonight.
Elon noted the ambient pressure test received a pass mark last night. The cryo pressure test is what sent Mk1, SN1 and SN3 Starships to Sto-vo-kor.

It’s a little dicey tbh. Thrust dome is being redesigned. Current one has four separate layers of steel in some places!

Will SN4 be doing a 150m hop or 20km?

Physically ready in a few weeks. Approvals may take longer.

UChicago Medicine doctors see 'truly remarkable' success using ventilator alternatives to treat C19.
What are your thoughts on this Elon?

Are you confident enough that a landing starship can get the skydive maneuver right on the first try? Seems risky with fuel farm being so close to landing pad. Or aiming for soft water landing first?
Elon Musk
@elonmusk · Apr 25, 2020
No, good chance of RUD (rapid unscheduled disassembly) event, but landing pad is separated from launch pad

What were the results of the new welds that you were talking about during the AMA livestream?
Elon Musk
@elonmusk · Apr 25, 2020
Improved process I was referring to was cylinder to cylinder circumferential welds to improve cycle time & reduce pucker. Those are still working their way through production.

These won’t be strictly coupled to ship serial number. Might be on SN5 or might just be used as a manufacturing pathfinder.

Also, the amount of stuff that goes in the backend to design such a solid Neural network is pretty understated.

Great labeling tools & talented human labelers really matter. It really is a skilled profession! Importance of good tools & infrastructure is underrated.

He goes over many types of rocket engines in his "Is Raptor the king of rocket engines" video, including the gas-generator cycle Merlin uses:youtu.be/LbH1ZDImaI8 I believe there are timestamps as well if you don't want to watch the whole video, but I would highly recommend it!
Elon Musk
@elonmusk · Apr 25, 2020
As usual for most things, building production system for Raptor is >1000% harder than designing it
