In his memoirs Sergei Khrushchev recounts recovery of what he believed to be a recoverable Samos, except the date given is the winter before tests of this configuration actually started. He relates that a second American capsule was recovered in the spring of 1961. It was equipped with a 30 cm lens and 100ís of metres of 10 cm wide film. Also recovered were a pear-shaped module made of fibreglass, and an inertial orientation system powered by electric motors. It may have been a SAMOS prototype. The capsule was found by tractor drivers, who disassembled it and used the film to wrap around the frame of their outhouse to provide some privacy in the treeless area. Unfortunately this ruined the film, preventing the Russians from developing it and discovering the technical capabilities of the system.

  • USA 160 - . Payload: MLV-10. Mass: 5,000 kg (11,000 lb). Nation: USA. Agency: NRO. Manufacturer: Martin. Class: Military. Type: Military naval signals reconnaisance satellite. Spacecraft: NOSS-3. USAF Sat Cat: 26905 . COSPAR: 2001-040A. Launch delayed from July 31. First of a new series of naval electronic intelligence satellites for the National Reconnaissance Office (NRO). The Lockheed Martin Atlas IIAS AC-160 put the vehicle in a transfer orbit. The phrasing of the launch commentary implied that the second burn left the payload in 'transfer orbit', but several observers saw the bright Centaur in the typical final deployment orbit of the earlier NOSS satellites. Therefore it seemed the first burn was to a transfer orbit of around 180 x 1100 km x 63 deg. The second burn at 1629 GMT put the Centaur and payload into an 1100 x 1100 km x 63 deg orbit. The design was apparently quite different from earlier generation NOSS satellites since only one companion satellite was deployed rather than two. Prime contractor for the new satellites was again believed to be Lockheed Martin Astronautics at Denver. The NRL probably continued to have a management and technical role in the program under overall NRO auspices.
