Why Moon:

                          We live in a unique two-world environment -- the Earth-Moon System. Earth’s offshore island, the Moon, is a stepping stone to the rest of the Solar System and a source of solutions to some of the most pressing environmental problems that we face on the Earth.

     The Moon is the closest source of materials for doing anything in space. Right now we have to bring every single bit of material that we need for space operations at great expense from the bottom of the Earth’s deep gravity well. It’s 22 times easier to launch from the Moon than from the Earth. The lack of an atmosphere on the Moon also makes it possible to launch materials using electric motors rather than expensive rockets.

    The Moon is more than 40% oxygen by weight. Oxygen is the main component of rocket propellant. Much of the rest of lunar soil is silicon (useful for making solar cells) and metals like aluminum and iron. Clean solar energy can be sent from space to the Earth using solar collectors in high Earth orbit made from lunar materials. A single solar power satellite could power an Earth city without carbon dioxide or other pollution.

Since these systems provide power at night, satellites could charge electric cars or generate hydrogen from water during off-peak times.

       The Moon is so close to the Earth (1.3 seconds for radio or light) that people can directly control lunar robots and other machines from Earth. Once lunar materials are available for construction in space, we can overcome many of the limits to space exploration that we currently take for granted. We can shield astronauts from cosmic and solar radiation. We can use beamed power to enable fast transportation in the solar system. We can build large telescopes and other astronomical tools to learn much more about the universe and how it came to be. In addition to using lunar materials to build solar-powered satellites, we can collect energy on the Moon’s surface and transmit it to the Earth.

     Thinkers such as Stephen Hawking, Carl Sagan, Konstantine Tsiolkovsky and Gerard K. O’Neill have suggested that it would be wise to spread humanity beyond the confines of our home planet in order to guarantee the preservation of our species. Space habitats constructed from material already in space (such as lunar or asteroid resources) can enable the near-term humanization of the solar system.

     By expanding the solution set to include resources outside the Earth’s biosphere, we can solve seemingly intractable problems of energy and the environment and repair the Earth.

                          The Moon is the only place where human have ever successfully reached except Earth. The Moon has 1/6 of the gravity then earth and for future flights in solar system it can be the best place to keep researching in the universe. In some researches of moon that has been found that from Moon’s sand it is possible to make water. And there could be water in freezing conditions on Moon where sun light has never reached. The surface of Moon might also content “He3” which can be a very good source of power. Moon has ‘helium 3’ which can be used as a power supply, there's enough helium-3 on the Moon to supply 10,000 years of energy needs on Earth.

                    The Moon has lots of secrets of its own and in some ways the nature of the Earth also depends on moons gravity. As the knowledge increases about Moon it seems Moon has lot of potential then we have thought about it.

                   It is the most eligible satellite, near the Earth, to make human base. This could provide us with lot of knowledge as there is Hubble telescope in space we can create such telescope on moon surface which can be build more powerful then the Hubble. If the earth’s gravity well is 22 steps dip then moon’s gravity well is only one step dip this shows the power required to escape to the planets energy. As the needed energy to escape from moon’s gravity is low so that we can use this base for future flights to outer part of solar system and to more beyond that.
