Wearing a training version of the pressure launch and entry garment, astronaut Edward T. Lu, mission specialist, waves at onlookers during an emergency egress training session at the Neutral Buoyancy Laboratory (NBL) near the Johnson Space Center (JSC). Lu, who moments earlier had simulated a parachute drop into the water, will join four other astronauts and two cosmonauts for one of next year's scheduled missions with the International Space Station (ISS).
