EDWARDS AIR FORCE BASE, Calif. — Rocketing into space? Some think an elevator might be the way to go.
That's the future goal of this week's $2 million Space Elevator Games in the Mojave Desert.
In a major test of the concept, robotic machines powered by laser beams will try to climb a cable suspended from a helicopter hovering more than a half-mile (one kilometer) high.
Three teams have qualified to participate in the event on the dry lakebed near NASA's Dryden Flight Research Center at Edwards. Attempts were expected from early Wednesday through Thursday.
Funded by a space agency program to explore bold technology, the contest is a step toward bringing the idea of a space elevator out of the realm of science fiction and into reality.
Theorized in the 1960s and then popularized by Arthur C. Clarke's 1979 novel "The Fountains of Paradise," space elevators are envisioned as a way to gain access to space without the risk and expense of rockets.
Instead, electrically powered vehicles would run up and down a cable anchored to a ground structure and extending tho
