New Delhi: The Indian Space Research Organisation (ISRO) today announced that India’s second lunar mission, Chandrayan II will be launched on July 15.

ISRO Chairman Dr. K Sivan informed that the composite body of Chandrayaan II is kept inside GSLV MK-III. The total mass of Chandrayaan II system is 3.8 ton; out of 3.8 ton, nearly 1.3 ton is the propeller.

India’s second moon mission, Chandrayaan II has three modules: the Orbiter, Lander (Vikram) and the Rover (Pragyan). The Rover will be house inside the Lander, according to ISRO. There will eight instruments on the orbiter. The sixth Imaging Infra-Red Spectrometer (IIRS) of NASA, the only foreign payload, will be a part of the Orbiter.

One of the primary instruments on board Chandrayaan 2 is the Imaging Infra-Red Spectrometer (IIRS) which will try to identify minerals and indicators of hydroxyl and water molecules.

“After launch into Earthbound orbit by GSLV MK-III, the integrated module will reach Moon orbit using Orbiter propulsion module. Subsequently, 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. Instruments are also mounted on Lander and Orbiter for carrying out scientific experiments,” said ISRO.

The landing on the moon is expected to be on September 6 or September 7 which happens to be the beginning of a lunar day. For one full lunar day, the lander and rover will function and carry out scientific experiments, ISRO chairman K Sivan informed.

ISRO scientists are conducting final tests on the orbiter’s antennae before it is shipped off to the island of Sriharikota for the launch next month.
