OV1-02
1965-078A
OV1-2 was mounted on the nose of an Atlas D together with a ballast OV. A scientific passenger pod was side mounted on the Atlas. The launch was under OAR Program 850B. The Atlas and SPP impacted in the vicinity of Guam.
OV1-2 studied radiation effects at intermediate altitudes. Mass was 86 kg and PM mass was 351 kg full.

Surveyor 2
1966-084A
Surveyor SC2 (Surveyor B) was launched at 1232 on 1966 Sep 20 by Atlas Centaur from Kennedy. The RL10A3-1 engined Centaur made a single burn direct ascent on azimuth 114.4 deg, cutting off at 1243. During the TCM one of three vernier engines, VE-3, failed. Repeated attempts to make the TCM resulted in the same engine failing to burn, so the mission was aborted. Engineering experiments were carried out but the spacecraft was tumbling. Finally the retro was fired and during the burn contact was lost at 0935 on Sep 22; calculations indicate the spacecraft impacted the Moon at 0318 on Sep 23 at around 4N 11W.
