On May 10, 2013, wearing the thermal undergarments for their extravehicular mobility unit space suits, NASA astronaut Terry Virts and European Space Agency astronaut Samantha Cristoforetti confer with space walk expert Allissa Battocletti about procedures and techniques they would later rehearse in the waters of the Johnson Space Center's Neutral Buoyancy Laboratory (visible through the window on the floor below). The ground based rehearsal was in support of a possible weekend space walk to be performed by two NASA astronauts aboard the International Space Station as they attempt to trouble-shoot an ammonia leak issue, discovered earlier in the week.
