But unlike Merlin engine which based on tried and tested technologies, Raptor also the first engine designed from the ground up for rapid repeated relights and crazy gimballing. No other rocket engines (except the Merlin) is expected to do so much. Usually they are not even expected to relight, and if they don't start at the exact right time reliably it's fine since it's just a scrub on the ground - it's not hurtling towards the ground sideways 2km up. It's capable of methane full flow, deep throttle, high gimbal, rapid multiple relight using internal torches and header tanks. I don't think there has ever been a more ambitious engine. The Starship test program is very much a Raptor test program.
14:45 - they had no way of knowing the condition of the vehicle seconds after the landing. His bias shows. Not only that, on all previous SN tests they also cut their feed minute(s) after whatever had happened.
19:10 - Perseverance has been a project in the making since 2012, back when SpaceX had just begun launching it's first cargo missions to ISS and Falcon 9 was still a baby in it's first design phase. NASA has been working on the Mars rovers since 1980's, that's three decades of experience under their belt with national budget backing them. Starship launches, at this stage, are experimental and began just a year ago. It has already tested and proved numerous core design elements. Funded by internal funds and Maezawa. He reeks of bias. He can't think clearly.
