The Space Elevator: A Revolutionary Earth-to-Space Transportation System, by Bradley C. Edwards and Eric A. Westling (November 2003) Leaving the Planet by Space Elevator, by Bradley C. Edwards and Philip Ragan (October 2006)
A space elevator built according to the Edwards proposal is estimated to have total cost of about $40 billion (that figure includes $1.56 billions operational costs for first 10 years). Subsequent space elevators are estimated to cost only $14.3 billion each. [14] For comparison, in potentially the same time frame as the elevator:
A space elevator, also referred to as a space bridge, star ladder, and orbital lift, is a proposed type of planet-to-space transportation system, [1] often depicted in science fiction. The main component would be a cable (also called a tether) anchored to the surface and extending into space.
A space elevator is a theoretical structure that would transport material from a planet's surface into orbit. [24] The idea is that, once the expensive job of building the elevator is complete, an indefinite number of loads can be transported into orbit at minimal cost.
Several space probes and the upper stages of their launch vehicles are leaving the Solar System, all of which were launched by NASA. Three of the probes, Voyager 1, Voyager 2, and New Horizons, are still functioning and are regularly contacted by radio communication, while Pioneer 10 and Pioneer 11 are now derelict.

The space fountain is a vertical version of the particle ring concept that forms a space elevator. The tethered ring is a dynamic structure that uses at least one complete and continuous non-orbiting ring with a diameter that is smaller than that of the planetary body.
