Here’s a little then and now of the Neutral Buoyancy Laboratory (NBL) for this throwback Thursday. 1. Astronauts Jerry L. Ross (left), and James Newman performed the first training session in the NBL . The training was a dress rehearsal of three Extravehicular Activities (EVA) the pair conducted during the July 1998 flight (STS-88) -- the first International Space Station assembly mission. 2. A group of U.S. Navy divers, Air Force pararescuemen and Coast Guard rescue swimmers practice Orion underway recovery techniques in the NBL to prepare for the first integrated test flight of NASA's Orion Spacecraft on top of the Space Launch System (SLS) rocket for Exploration Mission-1.
