SLIM exemplifies Japan’s pioneering spirit and drive in space exploration.
What is SLIM?
Japan has launched a lunar mission that aims to become the fifth country to land on the moon after the US, the former USSR, China and India. The mission, called Smart Lander for Investigating Moon (SLIM), is a small and agile spacecraft that will demonstrate precision landing and navigation technologies on the lunar surface.
What are its objectives?
SLIM was launched on September 7, 2023, along with an X-ray telescope called XRISM, which will study the origins of the universe. SLIM is expected to reach the moon by February 2024 and land near the Marius Hills, a volcanic region that may contain lava tubes.
The main objectives of SLIM are:
To test the ability of a small spacecraft to perform autonomous guidance, navigation and control during landing
To achieve a pinpoint landing within 100 meters of the target site
To collect scientific data on the lunar geology and environment
To demonstrate Japan’s technological capabilities and leadership in lunar exploration
Size of SLIM
SLIM is about the size of a refrigerator and weighs about 600 kilograms. It is equipped with a variety of sensors, including a camera, a laser altimeter, and a magnetometer. These sensors will be used to precisely determine the lander’s position and orientation during the landing maneuver.
Why is SLIM important for Japan and the world?
SLIM is a milestone for Japan’s lunar exploration program, which has been developing since the 1990s. Japan has previously sent two orbiters, Kaguya and SELENE-2, to study the moon from afar, but SLIM will be its first attempt to land on the surface.
SLIM is also important for the global efforts to explore and utilize the moon as a scientific and economic resource. SLIM will provide valuable information on the potential of lunar resources, such as water ice and minerals, that could support future human missions. SLIM will also contribute to the international cooperation and coordination of lunar activities, such as the Artemis program led by NASA.
SLIM is a demonstration of Japan’s innovation and ambition in space exploration. SLIM is one of the smallest and lightest lunar landers ever built, weighing only 130 kilograms and measuring 1.8 meters in diameter. SLIM is also one of the most cost-effective lunar missions ever launched, costing only $100 million. SLIM is expected to pave the way for more advanced and diverse lunar missions in the future.
