SLIM Moon Lander

The Japan Aerospace Exploration Agency (JAXA) has confirmed that its Smart Lander for Investigating Moon (SLIM) successfully entered the Moon’s orbit at 16:51 (Japan Standard Time, JST) on December 25, 2023. This mission focuses on demonstrating precision landing and obstacle detection technologies.

SLIM’s trajectory will take it into an elliptical orbit around the Moon, extending from the north to the south poles. This orbit will last about 6.4 hours, reaching a minimum altitude of 600 km (~370 miles) near the Moon (perilune), and a maximum of 4,000 km (~2,500 miles) at its farthest point (apolune). The insertion into this orbit was executed as planned, with the spacecraft currently operating normally.

The spacecraft entered the lunar orbit at 16:51 (JST) on December 25, 2023. Its current orbit is indicated by a light blue line. Upcoming maneuvers include:
 – Adjusting to a circular orbit at approximately 600 km (green line).
 – Transitioning to an elliptical orbit of approximately 600km x 150km (yellow line).
 – Finally, an elliptical orbit of about 600km x 15km (red line).

From now until mid-January 2024, SLIM will lower its apolune point and adjust to a circular orbit at around 600km. Following this, the perilune point will be reduced in preparation for landing. On January 19, the perilune will be lowered to 15 km (~9 miles), and descent towards the lunar surface will commence around 0:00 a.m. (JST) on January 20. The landing is scheduled for approximately 0:20 a.m. (JST) on January 20.
