Just how scorched was #Falcon9 B1049 after its 5th flight? Here's a refresher from its last return to port.
It's incredible what these boosters are able to endure, only to be sent right back to the launch pad!
Stay tuned for the first ever *6th* return of a Falcon 9 booster!

I think he just means the regular raptor beats the hot gas thrusters in performance for the maneuver (stemming from liquid prop and pumps which lead to light tanks... As opposed to the pressure fed hot gas system with heavy tanks)

Raptors will only do majority of the work flipping on the first couple flights right? Won't the hot gas thrusters do more of the work eventually?
Elon Musk
@elonmusk · Aug 19, 2020
It’s counter-intuitive, but Raptor has so much thrust at high Isp with liquid (high density) propellant & pump-fed (light tanks), that it beats hot gas for the flip. That said, hot gas beats the heck out of N2 for orbital manuevers & stabilizing ship if landing in high winds!

ULA has said that you need to refly a booster ten times for the economics of reusability to make sense. SpaceX is now up to six with Falcon 9.
Elon Musk
@elonmusk · Aug 19, 2020
Payload reduction due to reusability of booster & fairing is <40% for F9 & recovery & refurb is <10%, so you’re roughly even with 2 flights, definitely ahead with 3

Center locking F1 style nuts require a HUGE torque wrench and a HUGE nut (~70mm or more). Will one come with the New Roadster and will all service centers have one available that can torque the single nut to specs (over 300+ lb-ft)
Elon Musk
@elonmusk · Aug 19, 2020
Yes, it will have huge nuts haha

We really need a bigger one, so adults can squeeze in too. Guaranteed to make a party more fun. Works well with flamethrowers!

My favorite is one in tension, other DoF in compression. New Roadster wheels will only have one nut.

Deep learning continues to improve at astounding rates. In 2017 it costed $1,000 to train ResNet50 on the cloud, now it costs $10.
Thanks to AI accelerators and 'unlimited' compute in the cloud, AI algorithms are eating up 10x the amount of FLOPs per year.
