Watching the astronauts suit up for a spacewalk.  You can see it on your cable/satellite system, or online at NASA TV.

There is a HD feed at that is actually ahead of my satellite tv system feed!  That’s a bit strange to me…  the HD internet feed is a split second ahead of the satellite feed, and well ahead of the standard internet feed.  If you’ve got a broadband connection, the HD is the way to watch online!  Spacewalks are a lot of work, but you get a break beforehand…  you just float there while your astro-buddies do all the work getting your suit ready to go!  Once you step outside, though, it’s about 6 hours of steady work, and no coffee breaks.  Bathroom breaks are a bit different, too.
