Bradley C. Edwards is an American physicist who has been involved in the development of the space elevator concept.

Biography[edit]

Dr Edwards received his PhD degree in Physics from the University of Wisconsin–Madison in 1990.[citation needed] His thesis work was in astrophysics on the soft x-ray background. During his graduate work he worked on x-ray micro calorimeters and several sounding rocket and Shuttle payloads.

After receiving his PhD, Dr Edwards was hired as a staff scientist at Los Alamos National Laboratory where he was co-investigator on the ALEXIS satellite, developed superconducting tunnel junction detectors, a lunar orbiter, a Mars mission,[which?] a Europa orbiter and the world's first optical cryocooler.[citation needed] In 1998, Dr Edwards began working on the space elevator concept.[citation needed]

Edwards received funding from the NASA Institute for Advanced Concepts to examine the idea and published two papers in 2000 and 2003.[1][2] 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.[3][4]

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.[5][6][7][8]

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.[9]

Edwards spent eleven years working at the Los Alamos National Laboratory in New Mexico, researching advanced space technologies.[citation needed] He attempted a number of ventures associated with the space elevator concept before apparently leaving the field, spending six years as a senior engineer at Sea-Bird Electronics, an oceanographic company.[citation needed] He has recently[when?] started a new company to develop carbon nanotube technology.[10]
