>This engine makes everything else possible.

I have seen lot of tweets ( from highly intelligent people and engineers ) suggesting Starship is not possible. Raptor 2 is not possible.

But now it seems it really is coming.

It is easy to fault him for robotaxi and FSD, which a lot of people do. But sometimes he really does the impossible.

The chamber is still melting. Hopefully they can figure that one out.

Source? Several raptors have been fired for long duration and even multiple times. If the chambers would melt that should not be possible.

Of course RUDs of engines happened but they were the exception and not the norm.

Also, the only non-intentional engine RUD that I know of is SN8, where debris from ground destroyed the engine avionics at takeoff. Any other incident?

Elon himself said this was one of the major remaining problems in last night’s presentation.

But I think what he means is that currently the chamber gets to much damage to be full reusable on a daily bases over a long period of time, not that it doesn't work at all.

All the tweets from people who should know better tells me that even smart people are highly influenced by propaganda and bad takes from the media.

Seriously, it's only a matter of time before Elon Musk announces the space elevator.

Space elevator on earth doesn't really make much sense. On Mars maybe, it will happen on Mars way before it happens on earth.

Space elevators conflict with satellites, so not really advisable.

On Mars it would actually clash with one of the moons. But if you coordinate 1000s of pods correctly you can let the elevator wiggle so it never gets hit by the moon. It sounds insane but its doable.

Check out the talk about elevators from Mars Society conference.
