The Neil Armstrong Operations and Checkout Building high bay is filled with various pieces of flight hardware for Exploration Mission-1 (EM-1) and Exploration Mission-2 (EM-2) at NASA’s Kennedy Space Center in Florida. In this view taken on March 21, 2019, the forward bay cover for Orion (EM-1) is at far left in the foreground. Just to its right is the bay cover (EM-1). Behind these two pieces is the crew module adapter for EM-2. Further back, secured on a test stand is the European Service Module that will serve as the powerhouse for Orion. 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.
