WHY MOON MISSIONS?

“Giant impact hypothesis” suggests that when a large object smashed into the early earth, it gave rise to so many earth-related particles in space. When the number of these particles joined together, they gave rise to the celestial body named moon. Moon, unlike earth, consists of no atmosphere, lower gravity, no tectonic forces to deploy the surface and particles and other known or unknown conditions about moon gave rise to the conclusion that the moon has the particles of early earth preserved. Hence, Moon is also called to be preserved photocopy of earth. This gives rise to the curiosity if we may come to know about early earth through the evidence and study of the moon. 

Moon has an abundance of helium 3. Helium 3 does not reach earth due to its magnetic field, it repels away to the moon.  It is said that the moon has approx 1.1 million tons of helium 3 dumped on the moon's surface in vast quantities by solar winds. On this china says mining helium from the moon may help in solving the world’s energy crisis. Helium 3 is a light, radioactive isotope of helium. It could be extracted from the moon by heating the lunar dust to 600°C. Extracting even approx 8 tons of helium can cover the entire energy requirement of India for approx one year. 

Stephen Hawking says the earth is a good planet to live but there might occur reasons to escape from the planet as per safety. So, Moon could be that place. Dr. APJ Abdul Kalam used to say that the moon will be complex of earth, moon, and mars. In the future, we may launch rockets from the surface of the moon. 

Indeed, with the advantage of less gravity there, it sounds good to have a space station on the moon as well. India became the first country to find evidence of water on the moon, resulting in brilliant minds to work for the mission Chandrayan 2.  There are many missions in-process and innumerable ideas in the brain to work towards the space era with the development of humankind. The knowledge is (potential) power.
