On May 17, 2010 American astronauts Garrett Reisman and Stephen Bowen performed a seven hour and 25 minute spacewalk.

The new space-to-ground antenna they installed will increase the space station's ability to conduct two-way data, voice, and video communications. They put into place a new tool platform for the Dextre robot, and Bowen prepared six batteries that will be installed during the second and third spacewalks by loosening the bolts that hold the batteries in place. This was the first of three STS-132 spacewalks, 237^th conducted by U.S. astronauts, the second for Reisman and the fourth for Bowen. It was the 144^th EVA in support of International Space Station assembly and maintenance.
