It would be great to have some actual numbers. How did reuse work out for Falcon 9? How much does the reused boosters for SLS cost? What's the cost and performance of an expendable Starship vs SLS?

Wow, you have absolutely and shockingly little knowledge about any of this, do you?

I’m disgusted with Musk and can still see that SpaceX is the best thing going right now.

Why do Starship launches explode? Because SpaceX is pushing the envelope in multiple directions at once. Why is SLS “reliable”? Because it’s doing absolutely nothing new whatsoever, and doing it at an appalling cost in dollars and time.

Going to Mars takes about the same delta-v as the moon.

SpaceX launches 80% of the world's mass to orbit, they probably know what they're doing.

Starship is an extremely hard problem, and their aim is to reduce cost of getting mass to orbit by another 10x after Falcon 9 did the same.

Falcon 9 needs about 4% of fuel to land on a ship, 14% to return to launchpad

Why would you say they've had 100% failure rate? What did you think the reason was to launch and how did it fail?
