The 50 kg microsatellite will be able to take over and develop the role of large and medium-sized satellites to a large extent, at least in optical remote sensing. The group of Hokkaido University and Tohoku University paid particular attention to the importance of spectral imaging in earth observation and developed a spectral camera with the world's best wavelength selectivity using liquid crystal technology, which has been installed in five satellites so far and has demonstrated its effectiveness. In particular, it is effective in observing vegetation and agricultural fields, and by taking advantage of the mobility unique to smaller satellites, it has succeeded in imaging with a high degree of freedom with the high ground resolution, which has not been achieved even with large satellites. In addition, it has become possible to create detailed cloud 3D models using the characteristics that allow the satellite attitude to be flexibly changed. Such technologies are considered to be promising means from the viewpoint of global environmental changes and disaster prediction/monitoring. Furthermore, the cooperative operation of multiple aircraft, a constellation, opens the way to ultra-multipoint plasma observation in geospace. In this presentation, we will discuss the potential of this microsatellite, including its application to planetary science.
