Falcon 9's turnaround time has been decreased phenomenally. As the demand grows, do we expect to see its turnaround time to get much shorter (24hrs)? Or by the time we reach that kind of demand SpaceX would've transitioned to Starship which will have ~ >1 hour of turnaround time?
Elon Musk
@elonmusk · Mar 11, 2021
If 2021 manifest is met, SpaceX will do ~75% of total Earth payload to orbit with Falcon.
A single Starship is designed to do in a day what all rockets on Earth currently do in a year.
Even so, ~1000 Starships will take ~20 years to build a self-sustaining city on Mars.

Falcon 9 is almost always at max capacity. When it has “spare” performance, it flies back to land, which costs much less than using a droneship.
Our fundamental constraint is mass to orbit per unit time. Last year, SpaceX launched roughly double payload mass of rest of world.

“You won’t see any hydrogen usage in cars. The idea of a big market for vehicles powered by hydrogen fuel cells is very optimistic. Not even in 10 years, because the physics behind it are so unreasonable” — Herbert Diess, VW CEO @Herbert_Diess @elonmusk
Elon Musk
@elonmusk · Mar 11, 2021
Fuel cells should be called fool sells! Such a silly choice for cars. Not great even for a rocket upper stage imo, but at least not absurd.

Starship’s belly flop terminal velocity is already only like 75 m/s... what if... remove the 30 tones of landing prop, add 10 more tones of flaps, get that down to like 50 m/s and just use the world’s largest and most ridiculous net? 😂🤷♂️
Elon Musk
@elonmusk · Mar 10, 2021
Yeah, we talked about that internally. Could just have it land on a big net or bouncy castle. Lacks dignity, but would work. But, optimized landing propellant is only ~5% of dry mass, so it’s not a gamechanger.

Has the SpaceX team concluded with a better landing leg design for Starship?
Elon Musk

Might just catch the ship with the launch tower, same as booster

Battery energy density is the key to electric aircraft. Autonomy for aircraft could have been done a long time ago. Modern airliners are very close to autonomous.

Are there baffles in future designs to prevent slosh?
Elon Musk
@elonmusk · Mar 10, 2021
There were baffles, but one may have acted like a straw to suck bubbles in from above liquid/gas level.
Something similar happened on an early Falcon 1 flight, resulting in unexpectedly high liquid oxygen residuals at main engine cutoff.

This is a tricky one given that I believe said helium pressurization was added to the CH4 header tank to mitigate what happened with SN8.
That's why it's a test program, of course.
Elon Musk@elonmusk· Mar 9, 2021@austinbarnard45 SN10 engine was low on thrust due (probably) to partial helium ingestion from fuel header tank. Impact of 10m/s crushed legs & part of skirt. Multiple fixes in work for SN11.
Elon Musk
@elonmusk · Mar 9, 2021
Fair point. If autogenous pressurization had been used, CH4 bubbles would most likely have reverted to liquid.
Helium in header was used to prevent ullage collapse from slosh, which happened in prior flight. My fault for approving. Sounded good at the time.

Just prior to SN11 being placed onto the launch mount, SpaceX employees lowered down each and every landing leg. Testing them, so unlike during the SN10 flight; they will hopefully deploy properly this time.

Build 8.3 of FSD should be done QA testing by end of next week, so that’s roughly when download button should show up

Elon, what does the download FSD button do?
Does it put you in the queue to get FSD Beta, or download it immediately for anyone who has FSD and wants to try it?

Our goal for Patch 1.2 goes beyond any of our previous updates. We’ve been working on numerous overall quality improvements and fixes, and we still have work to do to make sure that’s what you get. With that in mind, we’re now aiming for release in the second half of March. 2/3

People we joked about how small Waymo’s geofence was.
Then actually went to chandler and realized it doesn’t even go everywhere in the geofence!
See the blue areas? That’s the only place where it can come pick you up.
It’s a total joke, and you’re a moron if you don’t get it
