Currently, NASA has no plans to repeat its ambitious attempt to deliver on the moon. At the same time, Russia is considering the establishment of lunar colonies, which will be located in natural volcanic caves and tunnels that protect people from the harsh conditions of the lunar surface.
"If it turns out that the moon has a cave that can provide protection from radiation and meteor showers, it could be even more interesting project than previously thought," - said Sergei Krikalev.
Krikalev managed to get aboard two space stations and flew on the space shuttle, and currently heads the Cosmonaut Training Center (CTC) im.Gagarina in Star City. He discussed with Russian scientists the ability to create lunar bases at a forum on the future of managed space flights.
In the photo above, which was made by Lunar orbiter, you can see a cave or hollow in the Sea of Tranquility. According to scientists, valley depth is 100 meters. Space station in lunar orbit, allowed to find some other caves. Researchers are studying these images to determine whether there is a system of lava tubes beneath the surface of the Earth’s satellite.
"The new finding, according to which the moon may be a rather porous body could significantly alter our approach to the development of lunar bases," - said Krikalev. "I do not have to dig the lunar soil and build walls and ceilings. Suffice it to use an inflatable module with a hard outer shell that is, roughly speaking, to seal the cave."
According to the Russian scientist, Boris Kryuchkov, the first such lunar colony could be built by 2030.
Krikalev spent in space, in total, more than two years. He made his first long flight in 1988 on the Soviet space station Mir. During his stay at the space station, from May 1991 to March 1992, managed to break up the Soviet Union, and the world has become the Russian space station.
He became the first Russian citizen, who flew on the space shuttle in February 1994.
