Associated space launch
OAO 1 (Orbiting Astronomical Observatory 1) was a solar-cell-powered satellite instrumented to make precision astronomical observations and to measure the absorption and emission characteristics of the stars, planets, nebulae, and the interplanetary and interstellar media from visible to gamma-ray regions.
ATLAS AGENA D R/B was lifted into orbit during the mission ‘Atlas SLV-3 Agena D | OAO 1’, on board a Atlas SLV-3 Agena D space rocket.
The launch took place on April 8, 1966, 7:35 p.m. from Launch Complex 12.
