KEY POINTS

Uniqueness of Chandraayan – 2

·        Chandrayaan-2 consists of an Orbiter, Lander and Rover, the Lander and Rover modules will separate and make a soft-landing on the surface.

·        ISRO has named the Lander module Vikram, after Vikram Sarabhai, and the Rover module Pragyaan, meaning wisdom.

·        It is the first time that ISRO is attempting to soft-land a module in extra-terrestrial space.

·        Chandrayaan-2 will make a landing at a site where no earlier mission has gone, near the south pole of the Moon.

Scientific insights

·        The 1471-kg Lander, which will remain stationary after touching down, will carry three instruments that will mainly study the moon’s atmosphere. One of these will also look out for seismic activity.

·        Lander and Rover are equipped with different kinds of camera to take create high-resolution three-dimensional maps of the surface.

·        It also has instruments to study the mineral composition on moon and the lunar atmosphere, and also to assess the abundance of water.

·        So far, all landings, human as well as non-human, have been in areas close to the Moon’s equator.

·        The south pole of the Moon holds possibility of presence of water. In addition, this area is also supposed to have ancient rocks and craters that can offer indications of history of the Moon, and also contain clues to the fossil records of early solar system.
