These days, the super small satellites attract interest, as a way to launch observation and practical demonstration equipment. At Nakasuka laboratory, three super small satellites have been developed. Pico-satellite for Remote-sensing and Innovative Space Missions (PRISM) is the third satellite, whose main mission is the high resolution image acquiring with specially designed extensible boom. PRISM has succeeded in main mission on orbit, which means the beginning of practical use of super small satellite. In this research, the specification and the operation result of PRISM are introduced as the great suggestion of the next generation super small satellite.
