60,000 miles up: Space elevator could be built by 2035, new study says

Imagine a ribbon roughly one hundred million times as long as it is wide. If it were a meter long, it would be 10 nanometers wide, or just a few times thicker than a DNA double helix. Scaled up to the length of a football field, it would still be less than a micrometer across — smaller than a red blood cell. Would you trust your life to that thread? What about a tether 100,000 kilometers long, one stretching from the surface of the Earth to well past geostationary orbit (GEO, 22,236 miles up), but which was still somehow narrower than your own wingspan?

The idea of climbing such a ribbon with just your body weight sounds precarious enough, but the ribbon predicted by a new report from the International Academy of Astronautics (IAA) will be able to carry up to seven 20-ton payloads at once. It will serve as a tether stretching far beyond geostationary (aka geosynchronous) orbit and held taught by an anchor of roughly two million kilograms. Sending payloads up this backbone could fundamentally change the human relationship with space — every climber sent up the tether could match the space shuttle in capacity, allowing up to a “launch” every couple of days.

Science fiction may be coming true.

Hundreds of challenges remain to be solved but as even NASA struggles to maintain an edge, the pay-off of a Space Elevator has never been clearer. The original idea of Konstantin Tsiolkovsky which Arthur C. Clarke turned into a novel could be the revolution space exploration needs.

Incredible Technology: How Future Space Missions May Hunt for Alien Planets | Physics as we know it. | Scoop.it

NASA's Kepler space telescope revolutionized the study of alien worlds after launching in 2009, and a number of other missions now stand poised to carry the burgeoning field into the future.

Over the next decade, NASA and the European Space Agency (ESA) aim to launch a handful of spacecraft that should discover thousands of additional exoplanets and characterize some of the most promising — the most apparently Earthlike — new finds in detail.
