Abstract
EXtreme ultraviolet spectrosCope for ExosphEric Dynamics (EXCEED) is an earth-orbiting space Extreme Ultraviolet (EUV) telescope mission. The satellite will be launched in 2012 by a Japanese new solid propulsion rocket and injected into the elliptic orbit around the earth. The orbital altitude is 900 to 1200 km for perigee and apogee respectively. EXCEED will make EUV spectroscopic and imaging observations of plasma space around various planets in our solar system. The wavelength range is from 60 to 145 nm and the resolution is 0.2 to 0.5 nm FWHM. It enables us to study Io plasma torus of Jupiter, and interaction of the solar wind with the upper atmosphere of the terrestrial planets and their escape. In this paper, we will introduce the mission overview and its instrument especially for holographic grating which is coated by Chemical vapor deposited silicon carbide.
