For an uninformed person like myself - what's the expectation for this launch? Is it expected to explode like the last two?
Well, yes, but the question is when. If everything goes right the booster will likely explode when it lands in the gulf . Starship itself will most likely explode on reentry somewhere over the Indian ocean. Now, I think the question is, will it explode before then, and of course that's why they do flight tests to find out.
10 minutes into flight starship is coasting in space for the next 30 minutes and should relight at around 40 minutes.
