But also keep in mind that Musk isn't personally designing and building everything SpaceX does. The staff at SpaceX deserve more credit than they get, especially Gwynne Shotwell.

> The detonation at the end was pretty spectacular too, but I suspect that structurally the tanks failed as the rocket hit the water vs anything that was an engineering failure. It's possible that SpaceX programed the AFTS to trigger some time after the rocket touched down in the water. Just to make sure that it completely submerges quickly. > I can easily imagine that flight 6 will be nominal end to end without any…
correct me if I’m wrong but I don’t think the second stage is meant to be caught. It will have legs to land on Earth/Mars without any landing infrastructure.
Very inspiring, glad I woke up to watch it. Congratulations to the SpaceX team. This is what competition looks like. It’s funny how last decade SpaceX had to sue the government to get more launches.
California officials reject more SpaceX launches, with some citing Musk's X posts https://twitter.com/shellenberger/status/1845131546501734440...

MIMO and nonlinear control theories are probably some of the hardest topics in all of engineering. SpaceX control system also has to compensate for the fuel moving inside their rockets so the control algorithms probably involve some kind of fast numerical fluid simulation. Another interesting thing SpaceX is doing is to use consumer-grade chips in triple redundancy configurations instead of using $100,000+ radiation-…
> control system also has to compensate for the fuel moving inside their rockets My stepfather worked as a programmer on the Apollo program, and the thing he always talked about as his biggest accomplishment was working on the "slosh problem" -- so yeah, props to the SpaceX team for managing that landing. And props to my stepdad for managing it on hardware that was... a billion times less capable? :-)
I'm just so happy to see this level of progress. This another big step for opening up space. To think that one day this will be considered normal. 150 Metric tons sent on a fully reusable rocket. Thats like a 747 to space.
So, reusable is supposed to reduce the cost. But the space shuttle was reusable and it has been shutdown because it was too expensive. What is the differences between the two?

This is especially prevalent when working in places like Seattle and SF. People ostracizing their coworkers because of wrongthink.
MDS like TDS is real. It's extremely toxic and it needs to stop. People's political beliefs are their own and connecting that to work is a recipe for disaster.
