Is that where you’re going to do meme review with Felix?
You do realize your doing meme review is kind of urgent, right?
(Though maybe @MrBeastYT will buy us some time on Sunday)

Tesla Model S is in the Ukrainian village Mars. How do you like this, @elonmusk? Looks like we beat you 😉

Hi @elonmusk , congrats on the 2nd profitable quarter in a row!!
Spoke with many ppl (friends, co-workers...) in my latest biz trip in China, many of them are really interested about M3 & asking if @Tesla is planning to make a “Long base version” etc C-Class 200L?
Thanks. $TSLA
Elon Musk
@elonmusk · 1. Feb. 2019
No plans to do so. Would recommend Model S.

Henry Briggs, the English mathematician who changed John Napier's logarithms into base ten logarithms, was born in February 1561. He was the first Professor of Geometry at @GreshamCollege, where the Royal Society was founded 63 years later

We’ll tweak the alloy over time, so it won’t exactly be 301, but close

Are you finding rocket engine design easier or harder as you develop over time?
Elon Musk
@elonmusk · 1. Feb. 2019
Well, my past mistakes do seem extremely dumb, especially the ones where I mistakenly thought I was smart

Rocket mass ratio is about the same for aluminum-lithium vs 301 stainless full hard at cryo, but latter costs way less, is tougher & doesn’t even need paint!

How many engines will be on SuperHeavy? Looks like the engine is to big to fit 31 of them on there.
Elon Musk
@elonmusk · 1. Feb. 2019
Still up to 31. Will probably fly with fewer initially in case it blows up.

Still planning to use methalox RCS thrusters and not cold gas? If so, how do you get those to be quick enough to function as RCS?
Elon Musk
@elonmusk · 1. Feb. 2019
Cold gas thrusters only. Will use body flaps & main engines for landing orientation, so won’t need high thrust reaction control. Simplifies things considerably.

Preparing to fire the Starship Raptor engine at @SpaceX Texas
Elon Musk
@elonmusk · 1. Feb. 2019
Initially making one 200 metric ton thrust engine common across ship & booster to reach the moon as fast as possible. Next versions will split to vacuum-optimized (380+ sec Isp) & sea-level thrust optimized (~250 ton).

I did a pretty thorough rundown on SS vs CC and I can see why you’ve moved that way. Are the large fin/flaps still part of the design and the way it’ll reenter? everydayastronaut.com/stainless-stee…
Elon Musk
@elonmusk · 1. Feb. 2019
To be clear, I’m confident that a stainless steel ship will be lighter than advanced aluminum or carbon fiber, because of strength to weight vs temperature & reduced need for heat shielding

Yes, ship needs pitch/roll/yaw control across wide Mach regime & angle of attack
Elon Musk
@elonmusk · 1. Feb. 2019
Will probably make booster legs/flaps same as ship, instead of like F9
