@elonmusk Do you happen to know if AWD Model 3s will get a peak power increase? Thanks!

Falcon rocket booster is aluminum-lithium & carbon fiber, which have low max temperature allowables. Super Heavy booster is stainless steel. Since it only goes to around Mach 8 or 9, moreover at high altitude, it needs no heat shield, not even paint.

I thought you were going with transpiration cooling so you wouldn't have to replace them after each flight. Will this system be the backup for the transpiration cooling, something in addition to the transpiration cooling, or a replacement to it.
Elon Musk
@elonmusk · 17 мар. 2019 г.
Transpiration cooling will be added wherever we see erosion of the shield. Starship needs to be ready to fly again immediately after landing. Zero refurbishment.

Fascinating. Why hexagonal shape?

Will you have an extra cooling system incase the transportation cooling system fails?
Elon Musk
@elonmusk · 17 мар. 2019 г.
Hexagonal tiles on most of windward side, no shield needed on leeward side, transpiration cooling on hotspots

Is transportation cooling still how you plan to actively cool the windward side of Starship?
Elon Musk
@elonmusk · 17 мар. 2019 г.
Only some of the hottest sections

After hopper planning on going straight to superheavy full size? Or intermediate development vehicle is planned?

Will the nosecone be used for the hop test?
Elon Musk
@elonmusk · 17 мар. 2019 г.
We decided to skip building a new nosecone for Hopper. Don’t need it. What you see being built is the orbital Starship vehicle.

Theoretically, can you throttle more with closed cycle since the lox / methane pumps are on separate shafts / systems and maintain the proper ratios?
Elon Musk
@elonmusk · 17 мар. 2019 г.
You can deep throttle on single shaft system by choking flow of fuel or oxygen between pump & combustion chamber. Problem is more with the tiny rocket engine that powers the pump, called a gas generator. That has to throttle *way* deeper than the main chamber.

Where will the first orbital flights of Starship occur from?
Elon Musk
@elonmusk · 17 мар. 2019 г.
Working on regulatory approval for both Boca Chica, Texas, and Cape Kennedy, Florida. Will also be building Starship & Super Heavy simultaneously in both locations.

@elonmusk @Tesla @LikeTeslaKim @BenSullins @teslainventory I have a idea for a model x software update. To have the falcon wing doors close automatically when you reach a certain speed. For a safety feature and you can obviously turn it off if need be. Tell me what you think.

Is throttling raptors pretty difficult? I can’t imagine figuring out how to run two totally separate preburners / turbopumps in unison and maintain accurate and precise throttling. You guys are crazy for figuring that beast out!!
Elon Musk
@elonmusk · 17 мар. 2019 г.
Raptor is *very* complex, even for a staged combustion engine. We’re simplifying as much as possible with each iteration. Throttling down to ~50% is hard, but manageable. Going to 25% would be extremely tough, but hopefully not needed.

Started rolling it out a few days ago. Always starts slow, find rare corner case issues, fix them, continue rollout …

Hopefully. Always many issues integrating engine & stage. First hops will lift off, but only barely.

Do y’all think #SpaceX will attempt some sort of test, With only one raptor or wait for the other two to arrive. It’s honestly been boggling my mind.
Elon Musk
@elonmusk · 17 мар. 2019 г.
First (really short) hops with one engine. Suborbital flights with three.
