Why a space elevator is now slightly less implausible
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听听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.听[]
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.
"Astronauts would ascend to 20 km by electrical elevator," inventor Brendan Quine听. "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,听, 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 landing at 12 miles above sea level will make spaceflight more like taking a passenger jet."
On the product page, Thoth said it is an original equipment manufacturer of "miniaturized payloads for space and UAV platforms." The company flew a greenhouse-gas sensor called Argus IR aboard the CanX-2 microsatellite in 2008.
Thoth Technology is also working on several missions still in the development phase, such as the听听补苍诲 an Extrasolar Spectroscopy of Planets mission that would probe for elements in the atmospheres of alien planets.
