കൊച്ചിയിലോ മുംബൈയിലോ സംഭവിച്ചേക്കാവുന്ന പ്രളയം രണ്ടുമാസം മുന്നേ പ്രവചിക്കാൻ കഴിയാത്തത് എന്തുകൊണ്ടാണ് ? അന്തരീക്ഷാവസ്ഥ പ്രവചിക്കുന്നത് അത്രമേൽ സങ്കീർണ്ണമാണോ? എങ്ങനെ പ്രവചനകൃത്യത മെച്ചപ്പെടുത്താം ? അന്തരീക്ഷാവസ്ഥയെക്കുറിച്ചും അതിന്റെ പ്രവചനരീതികളെപ്പറ്റിയും വായിക്കാം.

scientific objectives of Chandrayaan 2

What are the scientific objectives of Chandrayaan 2? Why explore the Lunar South Pole?

Moon provides the best linkage to Earth’s early history. It offers an undisturbed historical record of the inner Solar system environment. Though there are a few mature models, the origin of Moon still needs further explanations. Extensive mapping of lunar surface to study variations in lunar surface composition is essential to trace back the origin and evolution of the Moon. Evidence for water molecules discovered by Chandrayaan-1, requires further studies on the extent of water molecule distribution on the surface, below the surface and in the tenuous lunar exosphere to address the origin of water on Moon.

The lunar South Pole is especially interesting because of the lunar surface area here that remains in shadow is much larger than that at the North Pole. There is a possibility of the presence of water in permanently shadowed areas around it. In addition, South Pole region has craters that are cold traps and contain a fossil record of the early Solar System.

Chandrayaan-2 will attempt to soft land the lander -Vikram and rover- Pragyan in a high plain between two craters, Manzinus C and Simpelius N, at a latitude of about 70° south.

CHANDRAYAAN 2

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.
