I never really thought about orbit angles and such, but apparently its really important if you're sending objects up to service objects in space. The Hubble Telescope is at a very different orbit angle from the International Space Station, which means that it would be very difficult for a shuttle to get assistance from the space station in the event of an emergency. I just assumed in a Space Camp sort of way that, once you're in space, you just bang on some thruster buttons until it all works out. The New York Times has more.
Speaking of shuttles and the International Space Station, here's a shot of a space shuttle launch as seen by the ISS (via Mr. Sun/Warren Ellis):
And here's an aurora borealis shot from the ISS as well (via space.com):
