The latest mission from NASA has astronauts floating in the depths of space once again as Rick Linnehan installed the tool change out mechanisms of the Special Purpose Dexterous Manipulator robotic arm (a.k.a. Dextre) on the International Space Station.

The image above was taken last March 11 and shows Linnehan suspended from a Canadarm2 mobile foot restraint. The sixteen-hour-long mission was performed with the help of Expedition 16 flight engineer Garrett Reisman and involved the delivery of the first element of Japan's Kibo module along with the Canadian-built Dextre.

Unlike one of the previous missions involving the Endeavour, this one went off without a hitch. The space shuttle is still currently docked with the ISS and will see several more missions before its scheduled decommission in 2010.
