Bengaluru: The nation’s second Moon mission Chandrayaan-2 will have 13 payloads and a passive experiment from American space agency NASA, said the Indian Space Research Organisation (ISRO) on Wednesday. “Thirteen Indian payloads (8 on the orbiter, 3 on lander and 2 on rover) and one passive experiment from NASA,” said ISRO in a mission update. However, ISRO did not specify its objective. Also Read - 'I Voted Today': Astronaut Kate Rubins Casts Her Vote in The US Elections From Space | Here's How
The spacecraft with a mass of 3.8 tonnes has three modules namely Orbiter, Lander (Vikram) and Rover (Pragyan). All the modules are getting ready for Chandrayaan-2 launch during the window of July 9 to July 16, 2019, with an expected Moon landing on September 6, the space agency had said earlier this month.

The orbiter will orbit 100 km from the lunar surface, while lander (Vikram) will do the soft landing near the south pole of the moon, and Rover (Pragyan) will conduct in-situ experiments. The orbiter and lander modules will be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-III launch vehicle, said ISRO. Notably, the rover is housed inside the lander. Also Read - Nokia Wins $14.1 Million NASA Award to Set up 4G Network on The Moon
After the launch into earth-bound orbit by GSLV MK-III, the integrated module will reach Moon orbit using orbiter propulsion module. Subsequently, the lander will separate from the orbiter and soft land at the predetermined site close to the lunar South Pole.
Further, the rover will roll out for carrying out scientific experiments on the lunar surface, ISRO has said, noting that instruments are also mounted on lander and orbiter for carrying out scientific experiments. ISRO Chairman K Sivan had said in January, “We are going to land at a place where nobody else has gone-the Moon’s South Pole… It is unexplored region.”
Chandrayaan-2 mission is an advanced version of the previous Chandrayaan-1 mission about 10 years ago. Chandrayaan-1 had 11 payloads- five from India, three from Europe, 2 from USA and 1 from Bulgaria, and the mission had the credit for the 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.
