Discovery docked at ISS. Photo taken during yesterday's EVA.
Yesterday astronauts completed the third spacewalk of mission STS-128. The two spacwalkers replaced a gyroscope assembly, installed a Global Positioning System assembly (there are several on the station) and a payload attachment system, among other things.
Today astronauts will complete loading the Leonardo module with items for return to Earth and take a half day off.
What would you do with a half day of free time in the ISS?
