Soyuz 2.1b/Fregat-M | Luna 27

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.

Soyuz-2, GRAU index 14A14, is the collective designation for the 21st-century version of the Russian Soyuz rocket. In its basic form, it is a three-stage carrier rocket for placing payloads into low Earth orbit. The first-stage boosters and two core stages feature uprated engines with improved injection systems, compared to the previous versions of the Soyuz. Digital flight control and telemetry systems allow the rocket to be launched from a fixed launch platform, whereas the launch platforms for earlier Soyuz rockets had to be rotated as the rocket could not perform a roll to change its heading in flight.

The Roscosmos State Corporation for Space Activities, commonly known as Roscosmos, is the governmental body responsible for the space science program of the Russian Federation and general aerospace research. Soyuz has many launch locations the Russian sites are Baikonur, Plesetsk and Vostochny however Ariane also purchases the vehicle and launches it from French Guiana.

Payload and object details are usually published 1–2 days after launch.
