Boeing’s CST-100 Starliner prepares for electromagnetic interference and electromagnetic contamination (EMI/EMC) testing in a specialized test chamber at Boeing’s Space Environment Test Facilities in El Segundo, Calif. These tests were the final part of Starliner’s environmental qualification test campaign. EMI/EMC testing ensures that Starliner’s systems will function properly in the orbital radiation environment and also not interfere with other electrical systems on the International Space Station. Once back in Boeing’s Starliner facilities at the Kennedy Space Center in Florida, this same vehicle will be prepared to fly Starliner’s first crew during the Crew Flight Test mission later this year. NASA’s Commercial Crew Program is working with Boeing to return human spaceflight launches to the space station from U.S. soil.
