Luna 27 (also named Luna-Resurs 1) is a planned lunar lander mission by Roscosmos to send a lander to the South Pole–Aitken basin, an area on the far side of the Moon. The purpose is to prospect for minerals, volatiles (nitrogen, water, carbon dioxide, ammonia, hydrogen, methane and sulfur dioxide, and lunar water ice in permanently shadowed areas of the Moon and investigate the potential use of these natural lunar resources. On the long term, Russia considers building a crewed base on the Moon's far side that would bring scientific and commercial benefits. The lander will feature 15 science instruments that will analyse the regolith, plasma in the exosphere, dust, and seismic activity. The payload will include a sampling drill.
