STS-134. The1st EVA.

On May 20, 2011 American astronauts of the STS-134 crew Andrew Feustel and Gregory Chamitoff performed a spacewalk.

The astronauts retrieved and replaced materials exposure experiment packages, conditioned coolant lines in preparation for flowing ammonia during Sunday's EVA and installed two wireless communications antennas. But a malfunctioning carbon dioxide sensor in Chamitoff's spacesuit prompted an early end to the spacewalk before the crew could connect and route a large bundle of wiring for those new antennas. The EVA lasted 6 hours and 19 minutes.
