The study had the same simple title as this manuscript, The Space Elevator. and operation of a space elevator, a concept that up until this time had been. Space elevator designs often include a base station on Earth, an orbiting station in space, and a cable stretching between the two. The elevator car moves up. PDF | The objective has been to develop a viable scenario for the construction, deployment and operation of a space elevator using current or near future.

A huge, tall structure comes out of the ground and goes straight up through the clouds; at the end is a wonderful, mysterious castle.

Experts agree that the biggest drain of energy takes place when a vehicle blasts off, pushing through Earth's gravitational pull requires great amounts of fuel, but once they get out of our atmosphere, the rest is easy. If you could cut out that "blast off" portion, space travel would be easier and much more fuel-efficient.

In a Space Elevator scenario, a Maglev vehicle would zoom up the side of an exceedingly tall structure and end up at a transfer point where they'd then board a craft to the Moon, Mars, or any other distant destination.

If it all sounds like too much science fiction, take a look at the requirements for making the Space Elevator a reality.

A new material has been developed, however, called carbon nanotubes, that is times as strong as steel but with only a fraction of the weight. A carbon nanotube is an idea that makes this all sound much more achievable. In this concept, which is very fuel efficient and which brings space tourism closer common man uses the newly added concept of nanotubes to light. Impact or Collision Big issues requiring more study.

Debris is monitored using radar. Stud between Debris and meteors indicate space debris to be more hazardous. It must be noted number of impacts on ribbon, not as important as degradation cost due to impact. Health issues Fiber health focuses on three things, dose, dimension and durability. The bigger ones can't be integrated and smaller ones appear to dissolve quickly.

Loaded sectioned space elevator

It works by placing the system's midpoint station, and center of gravity, in a relatively low-Earth orbit and extending one cable down so that it points toward the center of the Earth and a second cable up so that it points away from the Earth.

The bottom end of the lower cable hangs down to just above the Earth's atmosphere such that a future space plane flying up from the Earth's surface would require 2. The length of the upper cable is chosen so that its endpoint is traveling at slightly less than Earth escape velocity for its altitude. This is done so that a spacecraft headed for higher orbit, the Moon, or beyond, can be placed in the proper orbit with only minimal use of its onboard propellant.

There are some properties of carbon nanotubes which proves that why carbon nanotube is used to build Ribbon tether CCT is more like an interconnected pair of layers that do not allow the walls to slide over one another or the sheet curvature to be on the multi-nanometer scale of CNTs.
