Luna 25



Luna 25, also designated the Luna-Glob-Lander, is a Russian lunar lander mission planned for launch in 2023. It is targeted to the south polar region of the Moon. There are two primary scientific objectives of the mission: to study composition of the polar regolith, and to study the plasma and dust components of the lunar polar exosphere.

The lander has a four-legged base containing the landing rockets and propellant tanks, an upper compartment holds the solar panels, communication equipment, on-board computers, and most of the science apparatus. Dry mass is about 800 kg, and it is expected to have roughly 1000 kg of propellant at launch. The lander has a Lunar Robotic Arm (LRA) to remove and collect the surface regolith. There are six science instruments. ADRON-LR is a gamma-ray and neutron spectrometer to study the surface regolith. ARIES-L detects charged particles and neutrals in the polar exosphere. LIS-TV-RPM, an infra-red spectrometer, measures surface water and OH in samples delivered by the LRA. The LASMA-LR mass spectrometer will measure composition of regolith samples from the LRA using laser ablation. The PML detector will study dust in the polar exosphere. STS-L is an imaging system, the European Space Agency is also planning to develop a Pilot-D demonstration camera for the mission.

Luna 25 is currently scheduled to launch no earlier than 2023, delayed from late September 2022. Launch will be on a Soyuz-2 Fregat into Earth orbit. It will fire the Fregat again to go into a lunar transfer orbit and from lunar orbit it will drop down to the surface. Landing will be in the region of the lunar south pole, the main landing site is at 69.55 S, 43.54 E, north of Boguslavsky crater. The reserve landing site is at 68.77 S and 21.21 E, southwest of Manzini crater. The lander is expected to operate on the lunar surface, studying surface regolith and exospheric dust and particles, for one year.
