Luna 22 Mission to Earth's Moon

Goals: Luna 22 was to orbit the Moon, imaging the surface and conducting remote-sensing measurements.

Accomplishments: In addition to its primary mission of surface photography from lunar orbit, Luna 22 studied the chemical composition of the lunar surface, recorded meteoroid activity, searched for a lunar magnetic field, measured solar and cosmic radiation flux, and continued studies of the irregular magnetic field.

Fast Facts
Luna 22 Facts Luna 21 was the sixth and final Soviet spacecraft dedicated to orbiting the Moon.

No major maneuvers were executed for nearly 5 months in order to reveal orbital changes which would indicate variations in the gravitational field.

The highly mission ended a few months after the spacecraft ran out propellant in September 1975.
