JAXAs SLIM Lunar Mission

Context

• The Japan Aerospace Exploration Agency (JAXA) achieved a major milestone with its "Smart Lander for Investigating Moon" (SLIM) entering lunar orbit, aiming for a soft landing on the Moon.

SLIM Mission

1. SLIM is Japan's second attempt at a soft Moon landing after the failure of the Hakuto-R mission in 2023.
2. SLIM, weighing around 190 kilograms, exemplifies precision technology, targeting a precise landing within 100 meters of the Shinoli crater in the equatorial region.
3. SLIM's unconventional journey to the moon, utilizing a fuel-efficient trajectory with a lunar flyby and a deep space loop, contributes to reduced mission costs.
4. Upon entering lunar orbit, SLIM utilizes an optical navigation system, guided by Kaguya orbiter maps, for accurate guidance to the landing site.
5. SLIM features crushable 3D-printed aluminum lattice landing legs, crucial for absorbing touchdown impact and ensuring proper orientation on the crater slope.

Scientific Payloads

1. SLIM carries a Multi-Band Camera analysing lunar minerals' composition, providing insights into the moon's geological makeup.
2. Hosting two small rovers, SLIM expands understanding of lunar terrain and underscores Japan's commitment to technological innovation in space exploration.

Implications

1. SLIM's success could revolutionize future lunar and planetary missions, enabling targeted landings at scientifically significant sites.
2. SLIM's innovative trajectory and landing technology contribute to cost-effective space exploration, positioning Japan as a key player in lunar and planetary exploration.
