Luna 22

"Lunik 22"
NSSDC ID: 74-037A

Description:
Luna 22 was a lunar orbiter mission. The spacecraft carried
imaging cameras and also had the objectives of studying the
Moon's magnetic field, surface gamma ray emissions and com-
position of lunar surface rocks, and the gravitational field, as well
as micrometeorites and cosmic rays. Luna 22 was launched into
Earth parking orbit and then to the moon. It was inserted into a
circular lunar orbit on 2 June 1974. The spacecraft made many
orbit adjustments over its 18 month lifetime in order to optimize
the operation of various experiments, lowering the perilune to as
little as 25 km. Manuevering fuel was exhausted on 2 September
and the mission was ended in early November.
