You've seen the Apollo 11 Saturn V launch. But probably not at 500 frames/sec, with commentary.
This is fabulous, and not just because there's fire and steam and hellishly incomprehensible forces. Although that helps. It's also, you know, science. And history. It's the very first step in a journey that would land two human beings on a body that's more than a light-second away from Earth, and return them safely.
With fire. And steam. And hellishly incomprehensible forces.
