NASA's Space Launch System program has completed its Critical Design Review, and major subsystems such as Orion’s launch abort system and the SLS RS-25 engines have recently completed successful testing. This is the first time since the 1970s that NASA has completed CDR on a major new launch vehicle. Experts from NASA and industry validated that the SLS, as designed, meets all system requirements and is within cost and schedule constraints. Boeing, Orbital ATK, Aerojet Rocketdyne and Lockheed Martin are building the SLS and Orion spacecraft for NASA's crewed exploration missions that will travel beyond the moon and into deep space. Boeing and Lockheed are using Michoud Assembly Facility in New Orleans, and Aerojet Rocketdyne is using engine test facilities at Stennis Space Center, Miss.
