Several days ago, Starship Flight 8 took off from its launchpad in Texas, slowly ascending through the atmosphere. About six minutes after that, the first stage of the rocket, called Superheavy, landed back at Starbase, where the rocket took off from. Two minutes after this, the second stage, still climbing into space, exploded. The launch before this one, Flight 7, had the same result, with the booster landing and the Starship itself exploding while trying to reach orbit. Why is this, and why has Starship failed so much?
