The objective of the CubeSat development is the establishment of research/development hub which enables the realization of innovative space deployable structures. The 3U CubeSat is designed as a pilot project to achieve the objective. This paper describes the CubeSat missions derived from the bigger development objective, and explains the system design of the CubeSat. Key Words: Gossamer Structures, Small Satellites, Nano Satellites, CFRP Boom 1. Introduction be launched in FY2018 using Epsilon rocket. Advanced lightweight space structures, especially membrane 2. Objective of CubeSat Development structures, have been widely studied for enabling future space applications. Applications that will benefit from such structures In order to establish a research and development hub for includes deorbiting system, solar array, reflectors, sun shield, space deployable structures, the present authors focus on the phased array antenna, solar sail, aerobrake/aerocapture system, following three key activities. and occulter.
