Lunar Orbiter 5
"Lunar Orbiter-E"
NSSDC ID: 67-075A
Description:
Lunar Orbiter 5 was designed primarily to photograph smooth
areas of the lunar surface for selection and verification of safe
landing sites for the Surveyor and Apollo missions. It was also
equipped to collect selenodetic, radiation intensity, and micro-
meteoroid impact data. The spacecraft was placed in a cislunar
trajectory and injected into three elliptical lunar orbits (apolunes
6029, 6066, and 4990 km, perilunes 195, 100, and 99 Km) for
data acquisition. It was stabilized in a three-axis orientation by
using the sun and the star Canopus as primary angular
references. A three-axis inertial system provided stabilization
during maneuvers and when the sun and Canopus were occulted
by the Moon. Communications were maintained by an S-band
system, which utilized a directional and an omnidirectional
antenna. The spacecraft acquired photographic data from
August 6 to 18, 1967, and readout occurred until August 27,
1967. Accurate data were acquired from all other experiments
throughout the mission. The spacecraft was tracked until it
impacted the lunar surface on command at 2.79 degrees S
latitude, 83 degrees W longitude (selenographic coordinates)
on January 31, 1968.
