Science instruments of SELENE (SELenological and Engineering Explorer) mission are proceeding to FM design phase following PM study phase for two years, although rescheduled after the failure of HII rocket launching. Fourteen science instruments are applied to the lunar surface studies of chemistry, mineralogy, topography, magnetism, and gravimetry by global mapping, lunar plasma environment studies and observation of the Earth's ionosphere. The prototype model of critical parts are manufactured and received mechanical and acoustic tests, and electric I/F test.
Design of flight models will be fixed after structural and thermal integration test performed in 2000 FY. The each models will be manufactured and received the environment test for 1.5 years.
