India’s second mission to the Moon, Chandrayaan-2, will be launched on July 15, Indian Space Research Organisation (ISRO) Chairman K Sivan announced on Wednesday. The mission will be launched at 2.15 am from Sriharikota. The mission includes a lander and rover for the first time in an Indian space mission. The moon landing is planned for September 6 or 7.
The spacecraft, with a mass of 3.8 tonne, has three modules — Orbiter, Lander (Vikram) and Rover (Pragyan).
The mission costs ₹603 crore for the spacecraft system and ₹375 crore for the launcher, a GSLV-MKIII. The lander and the rover will have the tricolour painted on them. The Asoka chakra will be imprinted on the wheels of the rover.
According to the ISRO, Orbiter, with scientific payloads, would orbit around the moon. Lander would soft land on the moon at a predetermined site and deploy Rover.
The scientific payloads on board Orbiter, Lander and Rover are expected to perform mineralogical and elemental studies of the lunar surface.
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. Rover is housed inside Lander.
After the launch into an earth-bound orbit by GSLV MK-III, the integrated module would reach the moon orbit using the orbiter propulsion module and subsequently, Lander would separate from Orbiter and soft land at the predetermined site, close to lunar South Pole, the ISRO said.
Rover would roll out for carrying out scientific experiments on the lunar surface, it said, noting that instruments were also mounted on Lander and Orbiter for carrying out scientific experiments.
Chandrayaan-2 is an advanced version of the previous Chandrayaan-1 mission, which was launched about 10 years ago.
Chandrayaan-1 had 11 payloads — five from India, three from Europe, two from the US and one from Bulgaria — and the mission had the credit for discovery of water on the lunar surface.
The 1.4-tonne spacecraft was launched using PSLV and the orbiter had orbited 100 km from the lunar surface.
