NASA astronauts Robert Behnken and Nicholas Patrick conducted the STS-130 mission's first spacewalk on Thursday, Feb. 11, 2010. The spacewalking pair finished all their assigned work and some get-ahead tasks. The Tranquility node and cupola were robotically maneuvered from Endeavour's payload bay, and then installed onto the port side of the Unity node. This was the first of three planned spacewalks for the STS-130 mission. Image Credit: NASA
