Overview
The Luna 26 orbiter mission has been in planning since at least 2011.[ Originally it was envisioned to be launched to the ]Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar ...
together with the lunar lander Luna 27
Luna 27 (Luna-Resurs 1 lander or Luna-Resource-1 lander) ,[ The orbiter's mass is about 2100 kg.][
The objective of the orbiter is to locate and quantify natural lunar resources that can be exploited by future landed missions. After completion of its primary mission, the spacecraft's orbit will be raised to about 500 km altitude to study ]cosmic rays
Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar ...

(ESA) had intended to contribute to this and other Luna-Glob missions in the manner of communications, precision landing, hazard avoidance, drilling, sampling, sample analysis and ground support. ESA cooperation with Russia on Luna 26 was discontinued on 13 April 2022 as a consequence of the Russian invasion of Ukraine.
