This paper reports the development of a laser ignition system for a super-small solid rocket motor to be used in the OMOTENASHI, a 6U-CubeSat that is the smallest lunar lander ever. A safe, compact, lightweight, and optimized system using a laser diode was developed to ignite the rocket motor. The development was successful, and the spacecraft equipped with the laser ignition system was delivered to NASA. The laser ignition system will be the first one for a spacecraft going on a deep space exploration.
