Chandrayaan-2 will be launched on July 15, 2019 confirmed Indian Space Research Organisation (ISRO) Chairman K Sivan on June 12. ISRO has released the first images of the moon lander.

Chandrayaan-2, India’s second mission to the moon, is expected to lift off at 2:51 am on July 15 from Sriharikota space centre in Andhra Pradesh. Chandrayaan-2 will be launched aboard GSLV MK-III launch vehicle

Everything you need to know about Chandrayaan-2

Chandrayaan-2 is a 3.8 ton spacecraft that has been constructed at a cost of more than Rs 600 crore. The cost of the launch vehicle GSLV MK III is expected to be around Rs 375 crore.

Chandrayaan-2 will comprise three modules, an orbiter, a lander named Vikram and a rover named Pragyan.  The orbiter will have eight payloads, while the Lander and the Rover will have three and two respectively.

While the Orbiter, which will have scientific payloads, would orbit the moon, the lander would make a soft landing on the moon at a predetermined site and deploy the Rover.

Following the launch, the lunar mission is expected to take many weeks before it prepares for a soft landing on the moon. ISRO plans to land Chandrayaan-2 near the South Pole of the Moon, a territory that hasn’t been explored by any other space agency.

According to ISRO Chairman K Sivan, Chandrayaan-2 will attempt the complex landing on the moon on September 6-7. The ISRO had earlier kept the launch window for the mission from July 9 to July 16.

How will Chandrayaan-2 land on the moon? How will the lunar mission work?

The two modules of Chandrayaan-2 – Orbiter and Lander- would be interfaced mechanically and stacked together as an integrated module and accommodated inside the launch vehicle. The rover will be inside the Lander.

Following the launch aboard GSLV MK-III, the integrated module would reach moon’s orbit using the orbiter propulsion module and subsequently, the Lander module would separate from Orbiter and make a soft landing at a spot predetermined by the ISRO scientists.

After the landing, the rover would be rolled to carry out scientific experiments on that part of the lunar surface where no mission has ever reached before. The lander is expected to have a mission life of 14 earth days or one lunar day. It will be solar powered.

The required instruments for carrying out the experiments have been mounted on the Lander. The mission will carry 13 Indian scientific instruments that will help analyse the minerals on the moon, map the moon surface and search for water. It will also carry a NASA instrument for LASER ranging.

The upcoming lunar mission of ISRO, Chandrayaan-2 is an advanced version of its previous mission- Chandrayaan-1, which was launched 10 years ago.

Chandrayaan was India’s first lunar probe, it was launched by the Indian Space Research Organisation in October 2008 and was in operation till August 2009.

The mission included a lunar orbiter and an impactor. The mission had 11 payloads, five from India, three from Europe, two from the US and one from Bulgaria.

The mission is credited with the discovery of water on the lunar surface. The spacecraft weighing 1.4-tonne was launched using PSLV-XL launch vehicle and the orbiter had orbited 100 km from the lunar surface.

The delay in Chandrayaan-2 was done to ensure robustness and to have full confidence that it will be a success.
