Over all these years of our civilization, we became sophisticated enough to have a second look at moon. International Space Station is about 350 kms above earth, rotating at a speed of 27.744 km/h. It takes about 92 minutes to orbit the earth and it does so 15.7 times a day. Compare these stats with that of moon. The average distance of moon is 384400 kms from Earth. It orbits the earth in 27.32 days. It has a thin atmosphere of Ar, He, Na, K, He and Rn with pressure ranging from 10 to the power minus 7 to 10 pascal. Landing a rocket ship would need at least ten times the effort needed to reach ISS. But building a base on moon definitely has some advantages over ISS. First of all, it will be on solid ground. Unlike ISS, which is purely experimentation, moon exploration can be financially rewarding if we can start a rear earth mining activity. Because of the thin atmo...
