Without the help of gravity, astronauts stumble, fall, and struggle to get back up on the surface of the moon.
I imagine a walk on the moon as a breezy, bouncy affair, my feet lifting off easily into oxygen-starved air before landing a perfect triple backflip. In reality, it's a lot harder than the movies would have you believe. This blooper reel shows astronauts tripping and stumbling over moondust before falling on their faces—and once they're down, it's rather difficult to get back up. Maybe we've been taking gravity for granted.
