    First generation photo surveillance; return of camera and film by capsule; SAMOS type satellite. Reached orbit but failed to deorbit and be recovered. 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.

    The first SV-5D Precision Recovery Including Maneuvering Entry (PRIME) maneuverable reentry vehicle was launched from Vandenberg by the first Series 7000 Atlas standard launch vehicle (SLV-3, Vehicle #7001). Managed by Space Systems Division, PRIME was designed to explore and advance the development of possible future manned and unmanned lifting body vehicles that would have the capability of operating like a spacecraft in orbit and of flying and maneuvering like an aircraft in the sensible atmosphere. Research was to be applicable to later Space Transportation System (STS) technology. The first test of the X-23A SV-5D lifting body re-entry shape. It was a zero cross-range suborbital flight, with recovery 6935 km downrange. The ballute deployed at 30.440 m, followed by the main parachute at 13,700 m, and the vehicle was descending within 275 m of the target point. Nevertheless the air-snatch was unsuccessful, and the vehicle sank. However 90% of the planned telemetry was successfully transmitted by radio.

    The second SV-5D Precision Recovery Including Maneuvering Reentry (PRIME) lifting body was successfully launched from Vandenberg by an Atlas booster. Although the SV-5D was not recovered, its on-board sensors provided excellent data on the effects of reentry. This was also the first spacecraft to perform cross-range maneuvers during reentry. The X-23A SV-5D lifting body vehicle demonstrated a 1055 km cross-range manoeuvre, but again air snatch failed.

    The third and last SV-5D Precision Recovery Including Maneuvering Entry (PRIME) flight vehicle, essentially a small maneuverahle reentry spacecraft, successfully performed cross-range maneuvers after being launched from Vandenberg on an Atlas booster. The series of three flights was so successful in demonstrating that a maneuverable spacecraft could survive reentry that the planned fourth flight test was cancelled. The full design 1145 km cross range was demonstrated, and the X-23A SV-5D lifting body vehicle was successfully snatched at 3700 m altitude, 8 km from the target point. With this success the rest of the project was cancelled, and the two remaining unflown X-22A's were sent to the USAF Museum at Wright Patterson Air Force Base.

    Launch delayed from July 31. Move of launch of the Intruder naval electronic intelligence satellites for the National Reconnaissance Office (NRO) from the Titan to the Atlas launch vehicle. 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 different from earlier generation NOSS satellites since only one companion satellite was deployed rather than two, in line with the lower payload capability of the Atlas. 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.
