Review article summarizes SLIM’s high-precision landing results, technologies, and implications for future missions.
The Smart Lander for Investigating Moon (SLIM), which was developed by the Japan Aerospace Exploration Agency (JAXA) and launched in September 2023, successfully landed on the Moon on January 20, 2024. Postlanding evaluation confirmed that its precision landing performance was better than 10 m, making it the world's first lunar lander to achieve high-precision landing. Furthermore, the mass at landing was approximately 200 kg, making it one of the lightest landers ever to succeed in a lunar landing. This lightweightness was the result of the development and application of various new technologies for weight reduction. These technologies are expected to be applied to the weight reduction of future lunar and planetary probes, thereby contributing to more frequent lunar and planetary exploration missions. This review article aims to provide an overview of SLIM's achievements by citing or referring to previously published papers.
