NASA Johnson Space Center is home to astronaut training. In the Astronaut Training Facility, astronauts push human extremes and prepare for missions in orbit and beyond.

In this 2013 photo, NASA astronaut Reid Wiseman, Expedition 40/41 flight engineer, participated in a spacewalk – or extravehicular activity (EVA) – training session in the Partial Gravity Simulator (POGO) test area in the Astronaut Training Facility at NASA Johnson Space Center.
