News: Japan’s Moon mission takes off, expected to land next February

 

What's in the news?

       After several weather-related postponements, Japan’s Moon-lander mission, called SLIM, finally took off.

       A successful landing on the Moon by the SLIM spacecraft would make Japan only the fifth country in the world to do so.

 

Smart Lander for Investigating Moon (SLIM):

       It is a compact robotic moon lander with no astronauts aboard.

       Called ‘Moon Snipper’ in the Japanese language, it has lightweight equipment for advanced observations and adaptable landings on resource-scarce planets, advancing exploration strategies.

 

Features:

       SLIM would be the smallest and lightest spacecraft to land on the Moon.

       The H-IIA rocket that took the SLIM in space also carried an X-Ray Imaging and Spectroscopy Mission (XRISM), a satellite meant for astronomical observations.

       The SLIM spacecraft was detached from the rocket 47 minutes after the launch and deposited in an Earth-orbit where it will perform orbit-raising manoeuvres over the next few days just like Chandrayaan-3 did in its initial phase.

       This is the first Moon-landing attempt being made by Japan Aerospace Exploration Agency (JAXA).

       SLIM is a pretty small spacecraft, weighing just about 200 kg.

       In comparison, the Chandrayaan-3 lander module weighed about 1,750 kg.

       The main objective of SLIM is to demonstrate precision landing, within 100 metres of the chosen site.

 

XRISM:

       XRISM was separated from the rocket 14 minutes after the launch and deployed in its intended orbit.

       XRISM will perform high-resolution X-ray spectroscopic observations of the hot gas plasma wind that blows through the galaxies, and its studies would focus on determining mass-energy flows, composition and evolution of celestial objects.
