INDIA”S ambitious Chandrayaan 2 Mission will be launched on July 15 early morning at 2 hours 51 minutes. “The Chandrayaan 2 Mission contains three components and the composite body of Chandrayaan 2 is kept inside GSLV MK-III. The total mass of Chandrayaan 2 system is 3.8 ton; out of 3.8 ton, nearly 1.3 ton is the propeller,” said Dr K Sivan,Director, Indian Space Research Organisation , at a news conference on Wednesday. The day we are going to land is either September 6 or September 7, that day happens to be the beginning of a lunar day. For one full lunar day, the lander and rover will be functioning and carry out scientific experiments,” he added. India’s second mission to the moon, Chandrayaan-2 will lift off at 2:51 am from Sriharikota in Andhra Pradesh. Space agency ISRO is giving final touches to the 3.8 ton satellite that has cost the country more than Rs. 600 crore. After launch, the Chandrayaan-2 satellite will take several weeks before it heads for a challenging soft-landing on the south pole of the moon, a territory that has never been visited by any space craft. Sivan said last-minute touches are being given Chandrayaan-2 and that and it will be launched using the “Bahubali” or the Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III).Chandrayaan-2 consists of an obiter, a lander named Vikram and a rover named Pragyaan and the nominal mission life of the lander is expected to be 14 earth days or one lunar day. The lander will also measure moon quakes. The Chandrayaan-2 satellite weighs 3.8 tons or roughly the weight of 8 full grown elephants, the rover is carried inside the lander and will do on site experiments on the lunar surface for about 14 days and it is solar powered.Chandrayaan-2 will explore a region of moon where no mission has ever set foot. The ISRO chief said the landing site, at about 70 degrees south latitude, is the southernmost for any mission till date. No country has attempted this before. The mission will demonstrate soft landing for future missions and it carries 13 Indian scientific instruments that will help analyse the minerals on the moon, map the moon surface and search for water. Though Chandrayaan-2 is an indigenous mission, India will use the Deep Space Network of NASA on payment basis for navigation and guidance.Dr Sivan, who tamed the agency’s “naughty boy”, the GSLV Mk II, said, “Chandrayaan-2 is exciting and as days approach, there is a kind of churning in the stomach since it is a complex mission.””It is the most complex mission ever to be undertaken by ISRO,” he said. “There will 15 terrifying minutes when the lander separates and before it soft lands on the moon, currently slated for September 6, 2019.The delay in Chandrayaan-2 was to ensure robustness and have full confidence it will be a success, Dr Sivan told Pallava Bagla.
