Associated space launch
The OV1 (Orbiting Vehicle 1) were small research satellite to be launched piggy back on Atlas ICBM test flights. They consisted in general of the OV1 satellite and the OV1-PM propulsion module (or upper stage) to reach orbit.
OV1-4 R/B was lifted into orbit during the mission ‘Atlas D | OV1-4 & 5’, on board a Atlas D space rocket.
The launch took place on March 30, 1966, 9:20 a.m. from 576B3.
