A view inside the Neil Armstrong Operations and Checkout Building high bay at NASAs Kennedy Space Center in Florida on March 21, 2019. In the foreground is the Orion crew module adapter for Exploration Mission-2 (EM-2). In the back, European Space Agency and Airbus workers are on the work stand that contains the European Service Module that will serve as the powerhouse for Orion for Exploration Mission-1 (EM-1). For EM-1, Orion will launch atop the Space Launch System rocket from Launch Pad 39B. The spacecraft will travel thousands of miles past the Moon on an approximately three-week test flight. Orion will return to Earth and splashdown in the Pacific Ocean off the coast of California, where it will be retrieved and returned to Kennedy.
