A rip-off of this YouTube video (Japanese, I think) with some captions added in, a Pink Floyd soundtrack dubbed over and the size of the asteroid stated as being 5 times larger, it is still *very* cool and very humbling to watch.
Given that they’ve taken such liberties with the original I can’t say that I trust the statements they make but it’s food for thought nonetheless.
It’s this kind of event that we hedge ourselves against when we finally manage to establish a presence off-world.
