NASA has provided an update on the first integrated launch of the Space Launch System (SLS) rocket and Orion spacecraft after completing a comprehensive review of the launch schedule. This first un-crewed mission, known as Exploration Mission-1 (EM-1) is a critical flight test for NASA's human deep space exploration goals. EM-1 lays the foundation for the first crewed flight of SLS and Orion, as well as a regular cadence of missions thereafter near the Moon and eventually to the asteroids and Mars. NASA is currently managing the program to a scheduled December 2019 launch.
