This is the first ground-test Lunar Orbiter to undergo a mission simulation under space-environment conditions. Boeing is building eight Lunar Orbiters for the National Aeronautics and pace Administration. The first launch is scheduled for mid-year.

Lunar Orbiter III Mission

The Lunar Orbiter 3 was a spacecraft launched by NASA in 1967, designed primarily to photograph areas of the lunar surface for confirmation of safe landing sites for the Surveyor and Apollo missions. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. The spacecraft was placed in a cislunar trajectory and injected into an elliptical near-equatorial lunar orbit on February 8 at 21:54 UT. The orbit was 210.2 by 1,801.9 kilometres (130.6 1,119.6 mi) with an inclination of 20.9 degrees and a period of 3 hours 25 minutes. After four days (25 orbits) of tracking the orbit was changed to 55 by 1,847 kilometres (34 1,148 mi). The spacecraft acquired photographic data from February 15 to February 23, 1967, and readout occurred through March 2, 1967.

Representatives of NASA Langley and Boeing signed the Lunar Orbiter contract on 16 April 1964 and sent it to NASA headquarters for final review. Three weeks later, on 7 May, Administrator James E. Webb approved the $80-million incentives contract to build five Lunar Orbiter spacecraft. Published in James R.
