The main component would be a cable (also called a tether) anchored to the surface and extending into space. An Earth-based space elevator would consist of a cable with one end attached to the surface near the equator and the other end attached to a counterweight in space beyond geostationary orbit (35,786 km altitude). The competing forces of ...
David Smitherman of NASA's Marshall Space Flight Center's Advanced Projects Office has compiled plans for such an elevator. The space elevator concept is a structure extending from the surface of the Earth to geostationary Earth orbit (GEO) at 35,786 km in altitude. The tower would be approximately 50 km tall with a cable tethered to the top.
English: A space elevator in motion, rotating with the Earth over the period of one sidereal day. As viewed from high above the north pole. The faint circle around the Earth represents the level of geostationary orbit. A satellite (green dot) is shown in geostationary orbit flying slightly behind the space elevator cable.
There are two approaches to constructing a space elevator. Either the cable is manufactured in space or it is launched into space and gradually reinforced by additional cables, transported by climbers into space. Manufacturing the cable in space could be done in principle by using an asteroid or Near-Earth object. [1] [2]
A space elevator would consist of a cable anchored to the Earth's surface, reaching into space. A space elevator is a proposed type of space transportation system. [34] Its main component is a ribbon-like cable (also called a tether) anchored to the surface and extending into space above the level of geosynchronous orbit. As the planet rotates ...
For the first time in nearly 150 years, the space elevator is out of the realm of sci-fi and into the orbit of mission possible. Two astronauts are stuck in space. Soon, the solution could be an ...
There are two points in space where an elevator's docking port could maintain a stable, lunar-synchronous position: the Earth-Moon Lagrange points L 1 and L 2.The 0.055 eccentricity of the lunar orbit means that these points are not fixed relative to the lunar surface : the L 1 is 56,315 km +/- 3,183 km away from the Earth-facing side of the Moon (at the lunar equator) and L 2 is 62,851 km ...
