Raytheon will continue to provide operations, maintenance and engineering services for up to four years to NASA's Neutral Buoyancy Lab and Space Vehicle Mockup Facility, facilities that are critical to safe human spaceflight. The NBL is the deep water pool astronauts use for spacewalk training. The SVMF hosts full-size mockups and simulators for the International Space Station, Orion capsule and commercial space modules. Both facilities are used to test scenarios and new equipment for human spaceflight.
