While most of the scientific instruments onboard the Chandrayaan2 so far have had only one mission to carry out, the IIRS have two separate objectives and a third smaller task to carry out.
First off, it’s going to be key in accomplishing one Chandrayaan 2’s mission objectives — analysing the presence of water on the moon.
And while its looking for water, the IIRS will also be mapping the minerals and volatilities of the moon.
Aside for its two primary objectives, the IIRS will measure the solar radiation that’s reflection off the Moon’s surface from 100kms in the lunar orbit.
