Japan Spacecraft Enters Lunar Orbit for Moon Landing on Jan. 20

Space News Japan :- Japan space agency announced that its lunar explorer, the Smart Lander for Investigating the Moon (SLIM), successfully entered the Moon orbit on Monday. The spacecraft is slated to land on the lunar surface on January 20, marking a significant step in Japan space exploration efforts.

Launched in September atop an H2A rocket, SLIM aims to position Japan as the fifth country to achieve a lunar landing, following the former Soviet Union, the United States, China, and India. The mission is part of the escalating global competition in space exploration.

Distinguished by its capability for pinpoint landings with unprecedented precision—less than 100 meters from intended targets—SLIM represents a technological advancement over conventional landers, which typically exhibit accuracy within several kilometers. The Japan Aerospace Exploration Agency (JAXA) envisions SLIMs success transitioning from an era of "landing where we can" to "landing where we want" for future Moon missions.

JAXA anticipates that a precise landing by SLIM will be crucial for missions requiring pinpoint accuracy on uneven surfaces, such as slopes, during potential searches for water on the Moon. This achievement could redefine the approach to lunar landings, emphasizing targeted precision.

In the event of a successful landing, JAXA aims to contribute to unraveling the Moon origins by conducting a composition analysis of rocks believed to be part of its mantle. This scientific endeavor could provide valuable insights into the lunar formation process.

Should SLIM miss the January 20 window, JAXA has identified February 16 as the next landing opportunity. The journey of SLIM began on September 7 when it was launched from the Tanegashima Space Center in southwestern Japan. The initial launch, scheduled for May, experienced delays due to a failed liftoff of Japan next-generation H3 rocket in March. Subsequent postponements occurred in August, attributed to adverse weather conditions. The successful entry into the Moon orbit is a positive development for Japan lunar exploration ambitions.
