Japanese Lunar Exploration Program the LUNAR-A mission, and a small data relay satellite. SELENE-3 aims to return about 100 grams of samples from the Moon surface. It will be launched around 2020. However, due to financial issues JAXA is currently facing, this mission may be merged into the option-3 of SELENE-X. SELENE-X will be launched in the late 2010s, in view of Japan’s participation in Humans Lunar Activities foreseen. The SELENE-X may perform either of the following demonstrations: There are other options under study, and will be determined after the international exploration strategy has been clarified. MELOS (Mars Exploration with Lander-Orbiter Synergy) is a
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.
