and Surveillance Command and consolidating the entire national security space apparatus in the Space Force. The USSF's Space Systems Command (SSC), in partnership with the National Reconnaissance Office, manages the National Security Space Launch (NSSL) program, which uses government and contract spacecraft to launch sensitive government payloads. NSSL supports both the USSF and NRO, as well as the Navy. NRO director Scolese has characterized his agency as critical to American space dominance and the Space Force, stating that NRO provides “unrivaled situational awareness and intelligence to the best imagery and signals data on the planet.” Additionally, in August 2021, former NRO deputy director Lt. Gen. Michael Guetlein became commander of Space Systems Command. Parts of the NRO will be integrated into the Space Force, their delta shaped insignia will be trimmed in black. National Aeronautics and Space Administration The National Aeronautics and Space Administration (NASA) is an independent agency of the United States government responsible for civil spaceflight. NASA and the Space Force's predecessors in the Air Force have a long-standing cooperative relationship, with the Space Force supporting NASA launches out of Kennedy Space Center, to include range support and rescue operations from Task Force 45. NASA and the Space Force also partner on matters such as space domain awareness and planetary defense operations. Space Force members can be NASA astronauts, with Colonel Michael S. Hopkins, the commander of SpaceX Crew-1, commissioned into the Space Force from the International Space Station on 18 December 2020. Spacecraft As of mid-2019, in reference to actual satellites in orbit being operated and controlled by the then-AFSPC, the Air Force reported that there were four Advanced Extremely High Frequency communications; one Space Tracking and Surveillance System-Advanced Technology Risk Reduction (ATRR, USA-205); five Defense Meteorological Satellite Program; six Defense Satellite Communications System satellites; five Defense Support Program; 31 Global Positioning System satellites; four GSSAP; five Milstar communications; seven Space-Based Infrared System (SBIRS, infra-red, launch warning); two SBSS; and seven WGS. The Space Force operates two Boeing X-37B spaceplanes on behalf of the Department of the Air Force Rapid Capabilities Office, which were previously managed by Air Force Space Command for five spaceflights. USA-299, launched in May 2020, was the first spaceplane mission operated under Space Force command. Personnel On 20 December 2019, all members of the former Air Force Space Command were assigned to the United States Space Force. Members of the United States Army,
