Special Issue “Smart Lander for Investigating Moon SLIM: Lunar Landing Results”

Abstract

The Small Lunar Lander for Investigating Moon (SLIM) successfully performed a soft landing on the Moon's surface on January 20, 2024 (JST), marking Japan's first-ever soft landing on the Moon. Its landing performance was evaluated as being within 10 meters or better, marking the world's first successful high-precision landing. By accurately landing near the target landing site, the multi-band camera successfully observed the composition of olivine, which is thought to originate from deep lunar interior. Additionally, the separation of two ultra-small rovers was successfully achieved just before landing. The rovers subsequently photographed the SLIM on the Moon and transmitted this valuable image to us. Furthermore, communication was established with the lander after it had endured three lunar nights, confirming its functionality. This special issue includes 14 papers detailing these achievements. The authors sincerely hope that this special issue will contribute to future mission planning.
