Intermission: Moon-Walking Bloopers
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.
