Space Shuttle Discovery is all loaded up with a grab bag of shuttle program favorites. Rendezvous, tech demonstrations, even an untethered EVA! Just be careful for the ghosts in the bathroom..
Space Shuttle Columbia is flying for the 17th time, carrying the International Microgravity Laboratory 2 payload. With fish, newts, and bubbles, it sounds more like a witch's brew than an advanced research laboratory. But don't let vague descriptions fool you! Also, who can leap long Spacelabs in a single bound? None other than IML Man, of course!
Errata: Around 4:48 I say "[...] sitting behind the Pilot on the middeck [...]" when, of course, the Pilot sits on the flight deck. Got myself all mixed up with MS1/MS3 out of position.
