According to a statement issued by ISRO, Chandrayaan-2, India's second lunar mission, will have three modules - Orbiter, Lander (Vikram) & Rover (Pragyan).
"The Rover is housed inside the Lander".
The Orbiter and Lander modules would be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-III launch vehicle.
After launching into earth-bound orbit by GSLV MK-III, the integrated module will reach Moon orbit using Orbiter propulsion module. Upon its successful landing, Vikram will release the rover, named Pragyan, which can move on the lunar surface for 500 metres.More news: CBD products are coming to a Kroger store near you
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.
Chandrayaan 2 coming after nearly 11 years since the Chandrayaan 1 that was launched on 22 October 2008, making more than 3400 orbits around the moon including a playing a crucial part in discovery of water molecules on the Lunar surface, until the spacecraft completed its lifecycle and its communication lost on 29 August 2009.
Once there, a series of orbit-lowering burns will bring the stack into a more circular orbit in which it revolves around the Moon once every 24 Earth-hours, a situation it will maintain for four days.
"Chandrayaan-2 will be launched on July 15 at 2.51 am", Sivan said at a news briefing. The lander will study moon-quakes near landing side, lunar thermal properties and plasma. The mission featured a lunar orbiter and an impactor but did not perform a landing on the Moon.
"It is going to be the most complex mission ever undertaken by ISRO", chairman K. Sivan was quoted as saying by local media.More news: 'Nexus' between Kim Jong-un and Central Intelligence Agency
Chandrayaan-2 had been due to launch in April 2018 but damage suffered by one of the legs of Vikram during testing pushed that back.
Once Chandrayaan 2 reaches the moon's orbit, it will revolve around the moon for 27 days to de-orbit the lander on its surface. The rover is expected to send data through the lander.
The 1.4-tonne spacecraft was launched using PSLV and the orbiter had orbited 100 km from the lunar surface. 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. "It will take four hours from the time of landing to the time rover comes out".
Chandrayaan-1, India's first lunar mission in 2008, cost $79 million and helped confirm the presence of water on the moon. When the mission had originally been approved in 2008, the cost was Rs 425 crore, excluding the launch costs and cost of the lander. Sivan explained that one side of the rover wheel has Asoka chakra and other has ISRO symbol that will be imprinted on the moon as it rover moves on the moon's surface.More news: Wholesale prices blip up 0.1% in May
