The STP-2 multi-manifest (rideshare) launch demonstrated the capabilities of the SpaceX Falcon Heavy launch vehicle and provided critical data supporting certification for future National Security Space Launch (NSSL) missions. In addition, SMC will use this mission as a pathfinder for the development of mission assurance policies and procedures related to the reuse of launch vehicle boosters. The STP-2 payloads are assembled from a host of mission partners including the National Oceanic and Atmospheric Administration (NOAA), the National Aeronautics and Space Administration (NASA), DoD research laboratories, and university research projects. STP-2 provides a unique space access opportunity for DoD and inter-agency science and technology missions that directly enhance the space capabilities of the U.S. and its allies and partners.
