Elon Musk @elonmusk
Replying to @Erdayastronaut and @SpaceX
Turbopump propellant flow path to achieve high chamber pressure is quite tricky. Requires an inducer & 2 impellers with ~100,000 shaft horsepower.

Elon Musk @elonmusk
About to complete SN5, ramping to an engine every 3 days this summer
>
Elon Musk @elonmusk
Mk1 & Mk2 ships at Boca & Cape will fly with at least 3 engines, maybe all 6 
>
Eric Ralph @13ericralph31
.... 7? ;) [ref: Starship previously had 7 engines]

Replying to @13ericralph31 @SPEXcast and 5 others
After the GoT finale, we dropped it to 6 [ref: GoT winner rules 6 of 7 kingdoms]

Why tho? 🐉

Elon Musk @elonmusk
3 sea level optimized Raptors, 3 vacuum optimized Raptors (big nozzle)
>
Eric Ralph @13ericralph31
So RaptorVac is back on the table for nearer term launches?

Elon Musk @elonmusk
Aspirationally

Elon Musk @elonmusk
Hoping for 380 sec Isp, but at least 370. Otherwise similar to sea level version.
>
SPEXcast @SPEXcast
With Raptor development progressing smoothly, how is vernior/RCS thruster development going for Starship? Still methane-based? Nitrogen, hydrazine, or something new?
>
Elon Musk @elonmusk
N2 for vacuum. Aero surfaces & high gimbal angle main engines for atmosphere.

Elon Musk @elonmusk
Replying to  @_ishanspatil @SPEXcast and 7 others
Aiming for 150 tons useful load in fully reusable configuration, but should be at least 100 tons, allowing for mass growth
>
Free Thinker @curiousmind44
What are your thoughts on ONeil structures @JeffBezos talked about?
>
Elon Musk @elonmusk
Replying to  @curiousmind44 @SPEXcast and 8 others
Makes no sense. In order to grow the colony, youd have to transport vast amounts of mass from planets/moons/asteroids. Would be like trying to build the USA in the middle of the Atlantic Ocean!

What happened to SN3? 

 

#1 was tested past its limits at McG, #2 was previously on Hopper, now its #4. Where's #3?

#3 was @ McG at the endish of last month, it did a 40second test fire there. So it's probably still there.

Odds are they're already iterating the hell out of Raptor and the earlier versions are outdated.

Until I see that thing flying for real, I'm just not going to be able to take it seriously.  Way too much like TinTin for me...

Fly-by-wire can make about any shape fly, videos on YouTube show lawn mower shapes buzzing about, so an aerodynamic design like Starship should be a snap.
