Chandrayaan 2 is an Indian lunar mission that will boldly go where no country has ever gone before — the Moon’s south polar region. Through this effort, the aim is to improve our understanding of the Moon — discoveries that will benefit India and humanity as a whole. These insights and experiences aim at a paradigm shift in how lunar expeditions are approached for years to come — propelling further voyages into the farthest frontiers.
The Moon is the closest cosmic body at which space discovery can be attempted and documented. It is also a promising test bed to demonstrate technologies required for deep-space missions. Chandrayaan 2 attempts to foster a new age of discovery, increase our understanding of space, stimulate the advancement of technology, promote global alliances, and inspire a future generation of explorers and scientists.
scientific objectives of Chandrayaan 2
The Moon provides us the best linkage to Earth’s early history and an undisturbed record of the nascent Solar System environment. While a few mature models do exist, the Moon’s origin still needs further explanations. Extensive mapping of the lunar surface will aid us in studying variations in its composition — an essential piece of information in tracing the Moon’s origin and evolution. Evidence of water molecules — discovered by Chandrayaan 1 — and the extent of its distribution on the lunar surface and sub-surface also require further studies.
The lunar South Pole is especially interesting because a larger section of its surface stays in the shadow than the North Pole. There is a possibility of the presence of water in permanently shadowed areas around it. In addition, the south polar region has craters that are cold traps, containing a fossilised record of the early Solar System.
Chandrayaan 2 will use the Vikram lander and Pragyan rover to attempt a soft landing in a high plain between two craters — Manzinus C and Simpelius N — at a latitude of about 70° south.
Chandrayaan-2, India’s second lunar mission, has three modules namely Orbiter, Lander (Vikram) & Rover (Pragyan). 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. The Rover is housed inside the Lander. After launch into earth bound 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 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.
All the modules are getting ready for Chandrayaan-2 launch during the window of July 16, to July 25, 2019, with an expected Moon landing on September 06, 2019.
