The space elevator is a challenging dynamics problem. It reaches through a gravity well, has a very unique aspect ratio, is in an environment with wind, passing gravity wells, solar wind pressure, ascending climbers and a moving anchor. An extensive study was undertaken by David Lang to simulate the system from deployment through operation. The results of those studies are below.
