October 16, 2006 UpdateLunar exploration satellite "SELENE" makes its appearance
On Oct. 13, the lunar exploration satellite, Selenological Engineering Explorer (SELENE), introduced itself to the public at the Tsukuba Space Center. The SELENE is 2.1 meters both in length and width, 4.8 meters in height, and three tons in weight including its two sub-satellites (each of which is about 50 kg.) The satellite is scheduled to be launched by an H-IIA launch vehicle from the Tanegashima Space Center in the summer of next year. It then will circulate on a lunar orbit 100 km above the moon for a year to elucidate the mystery of the lunar origin and development by observing the distribution of elements and minerals on the surface of the moon, its geographical features, surface structure, and gravity and magnetic fields in details.
