Astrophysicist and science communicator Neil deGrasse Tyson explains on the program NOVA ScienceNow how a Space Elevator could be constructed. You will see that travel from earth to space is possible through a space elevator. This future technology will change our ways by which we go to space. You will also be able to travel to space via this space elevator technology just by buying a ticket to space. In this video explore the potential of carbon nanotubes, whose strength and unique properties make them useful for a variety of applications. See animations of how carbon atoms bond to one another in different ways to make diamond, graphite, buckyballs, and nanotubes, and observe one method that is being researched to form and assemble carbon nanotubes into a long ribbon. Consider how a seemingly impossible application, such as an elevator from the surface of Earth to space, is now theoretically possible given this revolutionary new building material.

It costs about $500 million to take the space shuttle out for a spin. But what if there was another way to get to space? And what if that way were as easy and as cheap as riding an elevator? Well, some people think this kind of trip might be possible someday, thanks to something known as the Space Elevator, a 22,000-mile-long cable that could lift people and payloads straight to outer space.

This 12-Mile-High Elevator Will Reduce the Cost of Space Travel. Space enthusiasts and sci-fi fans, rejoice: The space elevator may be one step closer to reality. A Canadian space company was recently awarded a patent for a space elevator that would reach about 12 miles (20 kilometers) above the Earth's surface. Although space elevators have been considered a theoretical technology, they have been billed as a cheaper alternative to rocket launches, especially when it comes to sending heavy objects or people into space.

According to Thoth Technology Inc., the company that was awarded the patent, the U.S. patent allows for an elevator that would be 30 percent cheaper than the fuel required by a conventional rocket. Also, the system would be fully reusable, further reducing costs, the company said. A commercial spacecraft launch pad and runway would sit atop the 12-mile-high inflatable space.

"Astronauts would ascend to 20 km by electrical elevator," inventor Brendan Quine said in a statement. "From the top of the tower, space planes will launch in a single stage to orbit, returning to the top of the tower for refueling and reflight."

Space transportation options will increase if other companies contribute to the effort of developing alternatives to traditional rockets, noted Thoth CEO Caroline Roberts. For instance, SpaceX is testing self-landing rockets, and the company has made several attempts at landing a version of its Falcon 9 rocket on a sea barge drone, in a move that SpaceX says will eventually decrease launch costs.

"Landing on a barge at sea level is a great demonstration," Roberts said, "but land
