space travel would be more tangible if we built a space elevator. A space elevator‚ or space tether‚ is quite literally an elevator that goes from the lobby to Earth’s upper atmosphere. A space elevator is the best way to send supplies and people to an upper orbiting space dock. A space elevator will be feasible to build‚ allow us to build space ships that would require a space dock‚ and fulfill our dream of living among the stars. A space elevator is an old idea first theorized in 1895 by the Russian
