Micro/Nano-satellites with less than 50kg have been recognized recently as new promising tools for space development and utilizations with their extreme low cost and short development period. In Japan, many universities including university of Tokyo have been developing nano-satellites (less than 20kg) for educational objectives, starting with success of lkg CubeSat launched in 2003, and more sophisticated satellite such as CUTE-1.7+APD of Tokyo Institute of Technology or PRISM and Nano-JASMINE of University of Tokyo appeared recently which aim for practical missions such as world top level space sciences or low cost Earth observation. A new project just started in March 2010 in Japan funded by the government, seeking to establish all-Japan nano-satellite research, development and utilization consortium, which is expected to open a new way of low cost and fast space development and utilization.
