ISRO to launch Chandrayaan 2 on 15 July

The ISRO had earlier kept the launch window for the mission from July 9 to July 16.

Once the orbiter enters into orbit around the moon, it will release the lander, called Vikram, after Vikram Sarabhai. Chandrayaan-2 will carry 13 scientific satellites with it and weighs about 3.8 tonnes, the equivalent of eight elephants, Sivan said.

According to him, there is both convenience and science involved for choosing the South Pole.

The idea is to explore virgin territory on the lunar surface and analyze crust samples for signs of water and helium-3.

If all goes well, India would be the fourth country after the US, Russia and China to perform a soft landing on the moon and put a rover on it. But the soft landing is completely new, Sivan said.

The Orbiter and Lander will be able to communicate with earth directly while the Rover will share information, images and data to the Lander which inturn will shared with ISRO. Subsequently, rover will move on to the Moon.

Chandrayaan-2 has three modules - Orbiter, Lander (Vikram) & Rover (Pragyan). If successful, India will be only the fourth country to make a soft landing on the moon - in which vehicles touch down without damage - after the former Soviet Union, the US and China.

"The Rover is housed inside the Lander".

The cost of Chandrayaan 2 Mission mainly the satellite portion, including the support from foreign agencies as well as for navigation objective, is Rs. 603 crore, Dr Sivan added. The NASA experiment is reportedly a small retroreflector that will help measure the distance between Earth and the Moon with greater precision. After the launch, the satellite will take several weeks before it heads for a much-anticipated soft-landing on the south pole of the moon - a region that has not been visited by any spacecraft, NDTV reported. Scientifically, this part is expected to have a higher presence of water and minerals, the Indian space agency's chief said.

On July 15, a GSLV Mk III rocket carrying the Chandrayaan 2 stack of instruments will take off from the organisation's space port in Sriharikota.

The rover is expected to operate for 14 days on the Moon, ISRO chairperson K Sivan told the Times of India newspaper. It's one step in an envisioned progression that includes putting a space station in orbit and - eventually - landing a crew on the moon. Instruments on the lander and the rover would also carry out scientific experiments, the ISRO said.

Chandrayaan-1 had 11 payloads -five from India, three from Europe, two from the USA and one from Bulgaria - and the mission had the credit for discovery of water on the lunar surface.

A month after launch, it shot an impact probe onto the lunar surface and kicked up some soil, which was then chemically analysed.
