Instead of sending people, can we send material and robot to build a manufacturing base, residential areas, and communication center at moon.
We have to build robots here, who can work independently at moon building and doing things for us on earth. They can do the work like building medicines, creating communication center and building for future humans to come there.
Building such robots, will help also to build things on earth. Those robots soon can accompany humans to build homes here on earth.
Having a moon center may become a first launching place to more places on moon.
Eventually the moon robots can become sophisticated to do lot more complex problems which will help human race.
NASA building such robots will create tons on jobs on earth. These robots will use solar energy.
