On Wednesday, SpaceX launched its Starship to 40,000 feet, in the highest-altitude test to date. That part was a huge success. The landing, however, was a bit more dramatic. That s actually an understatement more specifically, the rocket crash-landed in a fiery explosion.
The launch had already been scrubbed once when an engine problem caused an abort with less than two seconds left on the countdown. According to Musk, the crash during landing wasn t related to that, and happened because of low pressure in the fuel header tank, causing touchdown velocity to be high.
I m not ashamed to admit I have no idea what any of that means, except that the rocket was going faster than it should have when it intersected with the earth. The rest is simple physics. Or chemistry, maybe? Probably both.
