NASA's Endeavour is in the middle of its final mission, and from the looks of it, it has been a memorable trip.

The crew from the space shuttle have conducted four spacewalks, installed various components to the International Space Station and collaborated with a crew of internationally based astronauts and cosmonauts from other space expeditions. Not too shabby considering they launched on May 16 and still have five more days in space left. They are set to return to Earth on June 1.

Here is a look at several photos from the mission thus far.
