Japan's SLIM Mission Achieves World's First Pinpoint Moon Landing, Survives Three Lunar Nights
  • Designed to investigate the Moon's origins, SLIM also tested technologies for low-gravity exploration.

  • The SLIM mission, which aimed to study a part of the Moon's mantle believed to be accessible at its landing site, focused on analyzing lunar mantle rocks and researching lunar water resources essential for future human bases on the Moon.

  • Japan's previous lunar landing attempts had faced setbacks, including the failed 2022 Omotenashi mission and a crash by a private company in 2023.

  • SLIM achieved a high-precision landing with a position error of only 10 meters, marking the world's first successful pinpoint landing on the Moon.

  • Despite challenges such as landing at a tilted angle that affected solar panel alignment, SLIM managed to operate for two days post-landing and conducted scientific observations with a high-spec camera.

  • After powering down with remaining battery capacity, SLIM surprisingly managed to gather energy and transmit images and data back to Earth.

  • The SLIM mission is part of a larger initiative, with multiple missions planned to explore the Moon in the coming years, reflecting a renewed interest in lunar exploration.

  • The lander successfully survived three lunar nights, enduring extreme temperatures that dropped to -130 degrees Celsius, and alternated between active and dormant phases.

  • Contact with SLIM was lost on April 28, 2024, and despite efforts to reestablish communication, JAXA concluded the mission on August 23, 2024.

  • JAXA's attempts to communicate with SLIM after the lunar nights were unsuccessful, leading to the decision to cease its activities.

  • JAXA plans to release a detailed summary of SLIM's achievements, expressing gratitude to everyone involved in the mission.

  • Overall, SLIM's ability to survive three lunar nights and conduct scientific observations is considered a significant achievement for the mission.
