USA-215, also known as NRO Launch 41 or NROL-41, is an American reconnaissance satellite, operated by the National Reconnaissance Office. Launched in 2010, it has been identified as the first in a new series of radar imaging satellites, developed as part of the Future Imagery Architecture programme,[2] to replace the earlier Lacrosse spacecraft.
USA-215 was launched by an Atlas V carrier rocket, flying in the 501 configuration, operated by United Launch Alliance. The rocket was launched from Space Launch Complex 3E at the Vandenberg Air Force Base, at 04:03:30 UTC (09:03 PDT) 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]
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 23 January 2015 it was in an orbit with a perigee of 1,105 kilometres (687 mi), an apogee of 1,116 kilometres (693 mi) and 122.99 degrees of inclination.[1]
