description SLIM Overview

SLIM was Japan's lunar lander built by JAXA to demonstrate pinpoint landing, making Japan the fifth country to soft-land on the Moon. It successfully touched down on January 19, 2024, achieving a precise landing within 100 meters of its target despite landing upside down due to an engine anomaly.

help SLIM FAQ

When did JAXA's SLIM land on the Moon?

SLIM touched down on January 19, 2024 in UTC, which was January 20 in Japan Standard Time. JAXA reported that the lander came down about 60 meters from its target site. [JAXA SLIM results](https://global.jaxa.jp/press/2024/01/20240120-1_e.html)

Why was SLIM called a pinpoint or Moon Sniper lander?

Its main technology goal was to land inside an ellipse of about 100 meters rather than aiming at a broad, relatively flat landing zone. This precision was intended to make future landings near scientifically valuable terrain more practical. [JAXA SLIM data](https://darts.isas.jaxa.jp/en/missions/slim)

Why did SLIM land upside down?

A problem with one of the main engines near touchdown changed the lander's attitude, leaving it resting on its side with its solar cells facing the wrong direction. JAXA still recovered useful landing and surface data after sunlight later reached the panels. [AP report on SLIM](https://apnews.com/article/641a5863-6df5-4a1a-9c3e-2a5a6a2cb6d1)

What small vehicles did SLIM carry to the lunar surface?

SLIM carried two autonomous probes, LEV-1 and LEV-2, which were released near touchdown. LEV-2, a small transformable rover, helped photograph the lander after it came to rest. [JAXA SLIM results](https://global.jaxa.jp/press/2024/01/20240120-1_e.html)
