NASA astronaut Reid Wiseman, an Expedition 40/41 flight engineer, attired in a training version of the Extravehicular Mobility Unit (EMU) spacesuit, is submerged in the waters of the Neutral Buoyancy Laboratory (NBL) near NASA's Johnson Space Center. Divers (out of frame) are in the water to assist in the rehearsal, which is intended to help prepare for work on the exterior of the International Space Station. Wiseman (along with European Space Agency astronaut Alexander Gerst and Maxim Suraev of Roscosmos) will launch to the space station aboard a Soyuz spacecraft on May 28, 2014, from the Baikonur Cosmodrome in Kazakhstan. They are scheduled to return to Earth in November.
