Here's a fun way to spend four minutes: watch astronauts explain explain the little details of life aboard the Space Shuttle. It's a little silly around the edges -- there's a fair amount of goofing around. Best part: yo-yos in space!! From NPR's description (they posted the video):
NPR requested from NASA this 1980s-era video with commentary by astronauts of various missions. The footage, which we edited, arrived on VHS. We don't know much about it, except that it's playful in tone, so we decided to have some fun with it, too. Here's an "instructional video" on survival in space, in case we ever decide to resurrect the program.
