Luna 28 (Luna Resource 2 or Luna-Grunt rover) is a proposed sample-return mission from the south polar region of the Moon.
Luna 28 will be composed of a stationary lunar lander and a lunar rover. The rover would bring soil samples back to the lander and transfer them into the ascent stage, which would launch and insert itself into a 100 km lunar orbit. While in lunar orbit, the soil-carrying capsule would be intercepted by an orbiting return module, which would perform all rendezvous operations and transfer the samples. After reloading the samples, the return vehicle separates from the orbiter and heads to Earth, while the orbital module continues its mission in the lunar orbit for at least three years. The mission was initially scheduled to be launched in 2027, but due to delays in the Luna-Glob program it is expected to be launched no earlier than 2030 as of August 2023.
