A Space Elevator Based Exploration Strategy
Abstract
Technological advances and recent studies have laid the groundwork for eventual construction of a space elevator. Within 15 years an operational space elevator could be running from Earth to beyond geosynchronous. The basic mechanical operation allows for low operational cost ($250/kg), high capacity (>13tons, >5tons/day/elevator), a range of destinations (LEO, GEO, Moon, Mars, Asteroids, and Venus), and minimal launch forces. The low risk operation of the space elevator would allow large scale robotic and human exploration of the solar system. An operational elevator will immediately move primary interest from LEO to GEO for many activities and open commercial space activities such as solar power satellite arrays for beaming power to Earth. Robotic exploration to all destinations would be able to use larger, fixed structures, more massive platforms and be launched for a fraction of current costs. Human exploration could start at GEO for maintaining commercial assets, and enhanced Earth-observing systems and then step to Mars where a receiving elevator could also be established. This paper will cover the basics of a space elevator and a comprehensive strategy for human and exploratory use of space based on the space elevator.
