The ₹603 crore Chandrayaan-2 consists of three segments - the Orbiter, the lander-Vikram and rover Pragyaan.
This will not be the first time that any object launched by India will leave its imprint on the surface of the Earth's only natural satellite.
The rover will be in constant contact with the lander, which will be in constant contact with the orbiter and also with the Indian Deep Space Network (IDSN).
India would join the U.S., China and the former Soviet Union on the list of countries that have completed a "soft" moon landing, or a touchdown that doesn't result in a crash landing.
"The LRA is a mirrored device that reflects laser signals to help mission team members pinpoint where a lander is as well as precisely calculate the moon's distance from Earth", explains Space.com, noting that the payload is of the same design as a device launched aboard Israel's doomed Beresheet moon lander earlier this year.
Evidence for water molecules discovered by Chandrayaan-1, requires further studies on the extent of water molecule distribution on the surface, below the surface and in the tenuous lunar exosphere to address the origin of water on Moon.
After a short time in lunar orbit, the lander and the rover will attempt to touch down on the moon's surface around September 6 or 7, if all goes as planned.
According to the information, there are more chances of finding water in the form of ice in this region, which remains mostly in shadow compared to the rest of the moon. A Full Dress Rehearsal (FDR), a process in which the participants will stimulate the exact process of the space launch, is scheduled for July 12 on Friday.
Amid a new global space race, India is preparing to launch a second mission to the moon.
Chandrayaan-2 is special because it will be the first spacecraft to conduct a soft landing on Moon's south polar region. One of these experiments led to the mission's most important discovery - it detected traces of water vapour.
'In addition, South Pole region has craters that are cold traps and contain a fossil record of the early Solar System'.
For about 14 days, the rover will explore this rarely studied lunar area, collecting samples and performing experiments.
The spacecraft will have a lunar orbiter, lander and a rover. It carried instruments for chemical, mineralogical and photo-geologic mapping of the lunar atmosphere and surface but all of it was done from afar, except the MIP.
The 27-kg, six-wheeled rover "Pragyan", fitted with cameras and instruments, would analyse the lunar soil. The aim of Chandrayaan-2 is to improve the understanding of the Moon. It runs on around 50 W of power and can travel 500 m at a speed of 1cm/sec. It is also expected to send back images and data to earth, every 15 minutes.
Something caused a giant hole on the Moon billions of years ago, and astronomers believe there's something big underneath the surface.
