According to Reuters, Russian scientists announced that they are hoping to set up the first colony on the moon by 2030, making use of a vast underground network of lava tubes through a possible entrance discovered in 2008 by Japan’s Kaguya spacecraft.
"KAGUYA (SELENE)" was launched by the Japan Aerospace Exploration Agency’s (JAXA) H-IIA Launch Vehicle at 10:31:01 a.m. on September 14, 2007 (JST) from Tanegashima Space Center (TNSC). The major objectives of the "KAGUYA" mission were to obtain scientific data of the lunar origin and evolution and to develop the technology for the future lunar exploration. "KAGUYA" consisted of a main orbiting satellite at about 62 miles (100km) altitude and two small satellites (Relay Satellite and VRAD Satellite) in polar orbit.
"This new discovery that the moon may be a rather porous body could significantly alter our approach to founding lunar bases," veteran spaceman Sergei Krikalyov, who heads Russia's Star City cosmonaut training center outside Moscow, said at a forum on the future of manned spaceflight.
