Launch
USA-215 was launched by an Atlas V launch vehicle, flying in the 501 configuration, operated by United Launch Alliance (ULA). The rocket was launched from Space Launch Complex 3E at the Vandenberg Air Force Base, at 04:03:30 UTC on 21 September 2010.[3] It was identified as NRO Launch 41, and was the twenty-third flight of an Atlas V; the vehicle had the tail number AV-025, and was named Gladys.[4]
Mission
The satellite's orbit and mission are officially classified; however, it has been located by amateur observers in a retrograde low Earth orbit. As of 14 February 2021, it was in an orbit with a perigee of 1,103 km (685 mi), an apogee of 1,105 km (687 mi) and 122.99° of orbital inclination.[1]
