Space Elevator Closer

Cool stuff.

A robot powered by a ground-based laser beam climbed a long cable dangling from a helicopter on Wednesday to qualify for prize money in a $2 million competition to test the potential reality of the science fiction concept of space elevators.

The highly technical contest brought teams from Missouri, Alaska and Seattle to Rogers Dry Lake in the Mojave Desert, most familiar to the public as a space shuttle landing site.

The contest requires their machines to climb 2,953 feet (nearly 1 kilometer) up a cable slung beneath a helicopter hovering nearly a mile high.

LaserMotive’s vehicle zipped up to the top in just over four minutes and immediately repeated the feat, qualifying for at least a $900,000 second-place prize.
