Comparison of Asian national space programs to fuel future energy demands in Asia. All three main Asian space powers plan to send men to the Moon in the distant future and have already sent lunar probes. Japan was the first Asian country to launch a lunar probe. The Hiten (Japanese: "flying angel") spacecraft (known before the launch as MUSES-A), built by the Institute of Space and Astronautical Science of Japan, was launched on 24 January 1990. In many ways, the mission did not go as was planned. Kaguya, the second Japanese lunar orbiter spacecraft, was launched on 14 September 2007. China launched its first lunar probe,
Marius Hills The hole, first discovered by the Japanese SELenological and ENgineering Explorer (SELENE) and then later imaged by the Lunar Reconnaissance Orbiter has been the subject of much research and speculation. There is a possibility that this feature could be a skylight in a lava tube. The depth of this hole is estimated to be between and its width is estimated to be several hundreds of meters. This tube could provide radiation shielding for a future underground lunar colony. However, it is unclear whether the tube is open or accessible. Two other lunar sites have been found by remote sensing, including
