Do you see starship landing on the Moon before Mars? Have you gone #moonfirst on us?

For sure moon 1st, as it’s only 3 days away & u don’t need interplanetary orbital synchronization

Any big changes happening between all the new serial numbers of Raptor? How's the testing coming along in Texas? Ready to stick another Raptor up in the hopper again any time soon?

Elon Musk @elonmusk
Raptor [SN5] liberated its oxygen turbine stator (appears to be mechanical, not metal combustion failure), so we need to update the design & replace some parts. Production is ramping exponentially, though. SN6 almost done. Aiming for an engine every 12 hours by end of year.

~730 engines/year!! Wow!

Full year production is usually ~70% of peak daily rate, so 500/year. Still, non-trivial at 100,000 tons of thrust/year.

Cost wise, how much more expensive is Raptor than Merlin to produce? Twice as much? Three times-ish.... I estimated Raptor being around $2,000,000 but that was just a roughly educated guess.

Elon Musk @elonmusk
More than that now, but <10% of that in volume, although much to be proven

Today Musk and a Raptor engine showed up at the Cocoa Starship Mk-2 site.

Also, the FAA test permit has been issued. The initial permit limits them to about 2,270 meters from the pad and 25 meters high, but that can be upgraded as flight envelopes expand.
