Japan Aerospace Exploration Agency(JAXA) announced that its Smart Lander for Lunar Exploration (SLIM) has successfully entered lunar orbit at 16:51 on December 25, 2023 (Japan Standard Time, JST).
SLIM’s lunar orbit will be inserted into an elliptical lunar orbit connecting the moon’s north and south poles every 6.4 hours, and the altitude at the point closest to the moon (near orbit) will be approximately 600 km (approximately 370 miles). . , 4,000 km (about 2,500 miles) at its furthest point from the moon (Apolune). The orbit change proceeded as planned, and the spacecraft is currently in a normal state.

Future Plans:
Green line: Circular orbit at an altitude of approximately 600km.
Yellow line: Altitude approximately 600km x 150km on an elliptical orbit.

From now on, the Apollone point will descend until mid-January 2024, and the orbit will be adjusted to a circular orbit at an altitude of about 600 km. After that, the perigee will drop and preparations for landing will begin. On January 19th, the near-orbit point will be lowered to an altitude of 15 km (approximately 9 miles), and the descent toward the moon will begin at around midnight (Japan time) on January 20th, with a scheduled landing on the lunar surface. There is. Around 0:20 a.m. on January 20th (Japan time)
