It has the fairly high reflectivity of 15-20 percent. But the space science community needs the higher reflective coating at 30.4 nm radiation for the future satellite missions, especially for the small satellite to reduce the size of optics. In this work, for developing a new multilayer mirror for Extreme Ultraviolet Imager (EUVI) onboard the Ionosphere-Mesosphere-upper Atmosphere-Plasmasphere mapping Satellite (IMAP), we report the performance of a multilayer consisting of Mg/SiC and the aging in reflectivity under atmosphere and vacuum
