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 gravity, which is stronger at the lower end, and the upward centrifugal pseudo-force (it is actually the ...
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 ...
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 ...
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]
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 ...

Pearson developed a space-based solar shield to counteract global warming and control Earth's climate, [11] and multi-winglets for improved aircraft performance. [12] Pearson has also written about the origins of the concept of the space elevator, and how it has been mistakenly attributed to Konstantin Tsiolkovsky. [13]
Carbon nanotubes may have the requisite tensile strength for the more technologically challenging Earth-based space elevator, but creation of nanotubes of the required length is a laboratory exercise, and adequate cable-scale technology has not yet been shown at all.
