A Soka University pico-satellite "Negai" measures mere 10cm cube and weights just one kilogram. Its orbit is 300km with inclination of 30 degrees. In 30 days or so after launch it will be dragged by the air and it is burnt out to become a manmade shooting star when reentering to the atmosphere. People believe wishing upon a shooting star makes their dreams come true. The main mission is to carry children's dreams recruited from the public microfilmed to be loaded on the satellite. Hence it is called "Negai" or "Wish." The technical mission is to space prove the high functional information system with inside triple-redundant fault-tolerant soft-core CPU embedded in an FPGA and reliable picture transmission system. This paper emphasized on the technical mission as well as how we operated so short mission life operation with 30 degrees inclination.
