The Luna-22 automated station is almost equivalent to the Luna-19 station in terms of purposes, structure
and onboard equipment.
The composition of the scientific payload had slightly changed. There were also engineering-technical
experiments carried out on the Luna-22 station aside from scientific experiments:
- eight friction pairs of the same type using materials of AMG6 and D16T alloys with different types of solid lubricant coatings;
- 12 types of coatings with different reflection characteristics.
Two optical-mechanical television cameras were installed onboard the spacecraft to obtain images of
certain areas of the lunar surface. The total mass of the Luna-22 lunar satellite after entering the
selenocentric orbit comprised 4,100 kg together with the KT module; moreover, the entire orbital flight
was performed together with this stage.
