stylish_lining

Japan recently landed a spacecraft called SLIM (Smart Lander for Investigating Moon) on the lunar surface, becoming the 5th country after the Soviet Union, the US, China and India to achieve a soft landing on the moon.

About SLIM

  • SLIM was launched by the Japan Aerospace Exploration Agency (JAXA) in September 2023 aboard the H-IIA rocket from the Tanegashima spaceport.
  • It aims to demonstrate precision landing within 100 metres through new technologies.
  • It also carried two mini robotic rovers developed by Sony and Tomy for reconnaissance.
  • The mission aims to revitalise Japan's space program which suffered setbacks like the failure of the flagship H3 rocket in March 2023.

Objectives

  • The mission aims to observe X-rays coming from deep space and to identify their wavelengths with unprecedented precision.
  • It will use state-of-the-art spectroscopy to measure changes in the brightness of celestial objects at different wavelengths.
  • It detects X-rays with energies ranging from 400 to 12,000 electron volts. (For comparison, the energy of visible light is 2 to 3 electron volts.)
  • This range will provide astrophysicists with new information about some of the universe's hottest regions, largest structures, and objects with the strongest gravity.

Future Moon Missions

  • ISRO (India): LUPEX with JAXA, Chandrayaan-4
  • NASA (USA): Lunar Trailblazer Mission, Viper Rover, Artemis 2-6 (Manned mission).
  • ROSCOSMOS (Russia): LUNA 26-28, ORYOL
  • CNSA (China): Chang'e 6-8
  • JAXA (Japan): Destiny+
