CUBESAT SEMI-HARD MOON IMPACTOR: OMOTENASHI

摘要

A 6U CubeSat "OMOTENASHI" will be the world's smallest moon lander which is launched by NASA SLS rocket in 2019. Because of its severe mass and size limitation, soft landing to the surface will be impossible. Hence, semi-hard landing scheme is adopted. That is, OMOTENASHI is decelerated to within around 30 m/s by a small solid rocket motor and shock absorption mechanism is developed for the high speed impact. Ultra small communication system (X-band and P-band) is also developed. It observes radiation environment of Earth and moon region with portable dose meters. This paper shows the latest design and development status of OMOTENASHI.
