the first micro-laser propulsion onboard the KKS-1 microsatellite was deployed in space as a piggyback payload to the Greenhouse Gases Observing Satellite called "Ibuki." An in-space test was planned using laser propulsion; however, due to a malfunction of the onboard CPU, the test was delayed until the recovery of the KKS-1. In this paper, current satellite trends toward smaller and lighter satellites are briefly summarized. We also propose micro and laser propulsion that operates in two modes
