Classified communications and data relay satellite for the National Reconnaissance Office.
AKA: Aquila;Capricorn;Nemesis;NROL. Status: Operational 1976. First Launch: 1976-06-02. Last Launch: 2014-05-22. Number: 17 .
Atlas flight AV-046 left the USA 252 payload in an 840 x 35745 km x 20.7 deg geostationary transfer orbit. It was expected to enter geostationary orbit and was thought to be a QUASAR communications and data relay satellite for the National Reconnaissance Office - either QUASAR 18 or 19, uncertain due to the difficulty of distinguising early QUASAR and JUMPSEAT satellites in the 1970s.

Classified satellite for the National Reconnaissance Office. It was likely that it was a technology test satellite combining equipment for several future projects, including a prototype COBRA BRASS infrared early warning satellite sensor. The project seemed to have been several years behind schedule (based on the launch vehicle serial number.

NROL-61 mission was launched on Atlas AV-065 into a geostationary transfer orbit. The satellite was thought to be an NRO (National Reconnaissance Office) data relay communications satellite in the QUASAR series, although there was a chance that it instead had a signals intelligence payload. The
payload made orbital maneuvers to raise its perigee, and hobbyists tracked the satellite in geostationary orbit at 92 deg E, over the Indian Ocean.
