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,
Explorer 34 perpendicular to the ecliptic plane. Like the earlier IMPs, this spacecraft was instrumented to study interplanetary magnetic fields, energetic particles, and plasma. The spacecraft optical aspect system failed on 4 March 1969. Otherwise, useful data were acquired until just before spacecraft reentry, which occurred on 3 May 1969. Explorer 34 Explorer 34, also called IMP-4 and Interplanetary Monitoring Platform IMP-F, was an American satellite launched as part of Explorers program. Explorer 34 as launched on 24 May 1967 on Vandenberg Air Force Base, California, United States, with Delta rocket. Explorer 34 was the fourth satellite of the Interplanetary Monitoring Platform.
