Boeing March 2019 Progress Photos Technicians at Boeing’s Space Environment Test Facility in El Segundo, California position the CST-100 Starliner spacecraft inside an acoustics test chamber. This Starliner, slated to fly in Boeing’s Crew Flight Test (CFT), underwent an environmental qualification test campaign in March, experiencing rounds of acoustics vibration, thermal vacuum and electromagnetic interference and electromagnetic contamination testing. These tests prove Starliner’s design is capable of handling the harsh environments of launch, ascent and orbit and also prove that the electronics systems will operate in space and not interfere with other satellites or the International Space Station. CFT is Boeing’s crewed flight test of Starliner and part of NASA’s Commercial Crew Program, which will return human spaceflight launches into low-Earth orbit from U.S. soil.
