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
Far Ultraviolet Spectroscopic Explorer (410 nmi) in altitude, with an inclination of 25 degrees and just less than a 100-minute orbital period. Its Explorer designation is Explorer 77. On 12 July 2007, "FUSE" final reaction wheel, which is required for accurately pointing a spacecraft, failed and efforts to restart it were unsuccessful. An announcement was made on 6 September that because the fine control needed to perform its mission had been lost, the "FUSE" mission would be terminated. Although the original specification was to have a Wolter-type grazing incidence telescope, the final design of the "FUSE" telescope comprises four individual mirrors. Each of the
