Russian Lunar Polar Probes, 2015-2020
The last Russian probe to the Moon was Luna 24, which returned a 176 gram sample to Earth, in 1976.
The Russians are finally planning to return, with Luna 25 scheduled for 2015. The plans are currently as follows:
These may be followed up on by manned missions.
From these sources, there is a lack of indication of the Russians intending to set up permanent colonies on the Moon or develop major manufacturing in space, and Russian officials still talk of a manned mission to Mars being the ultimate objective, unfortunately.
A bit of history:
The Soviets were the first to go to the Moon with unmanned probes, and the last in 1976 to soft land a spacecraft on the surface (as of the time of this writing in 2012). The Russians were the first to do many things in the 1959-1966 period, including the following:
However, the Russians never sent astronauts, as they "lost the space race" to the Americans when Apollo 11 landed men on the Moon in 1969 and returned samples to Earth.
The first Soviet attempts in 1969 to robotically return lunar samples failed, including before Apollo 11 was launched (and a later rush attempt crashed on the Moon while the Apollo 11 men were there).
Nevertheless, the Russians did have three successful robotic sample return missions starting in 1970, which were Luna 16, Luna 20, and Luna 24, and also deployed two robotic vehicles to drive around exploring the Moon, Luna 17 and Luna 21, which deployed the Lunokhod 1 and Lunokhod 2 rovers.
That was all in the era of the Soviet Union when they were competitors with the United States.
It has yet to be seen how committed and successful the Russians will be in the next decade, and how much of the work will be in cooperation with other governments or multinationals rather than nationalistic strategic competition.
The above plans have multiple sources which corraborate each other fairly well, as the Russians are a lot more open now.
