Edwards received funding from the NASA Institute for Advanced Concepts to examine the idea and published two papers in 2000 and 2003.[5][6] He proposed methods for deploying a space elevator and overcoming perceived obstacles such as orbital debris, anchoring, climber design, and power delivery and examined construction costs and scheduling, laying the groundwork for current[when?] discussions.[7][8]
Edwards also published two books on the subject, The Space Elevator: A Revolutionary Earth-to-Space Transportation in 2003 and Leaving the Planet by Space Elevator in 2006 which gained coverage on major news media.[9][10][11][12]
In interviews, Edwards has estimated that price per pound of launching into low Earth orbit could be reduced to 100th the cost of Shuttle missions.[13]
