Space Elevators Face Wobble Problem

Posted by ScuttleMonkey on from the all-part-of-the-ride dept.

NewScientist is reporting that while the strength of the tether has long been considered the main problem in building a space elevator, a new study suggests that a dangerous wobbling problem may also be a serious obstacle. "Previous studies have noted that gravitational tugs from the Moon and Sun, as well as pressure from gusts of solar wind, would shake the tether. That could potentially make it veer into space traffic, including satellites and bits of space debris. A collision could cut the tether and wreck the space elevator."

    A collision could cut the tether and wreck the space elevator. Not to mention hurling whomever/whatever is the payload into space with the force of the largest man-made slingshot.

    A broken space escalator would become a stairway to heaven, and if Led Zeppelin has taught us anything, it's that a Stairway to Heaven doesn't make any damn sense at all unless you're already so high you're practically in space already.
