The very minimum requirement for a space elevator is, obviously, a cable strong enough to support its own weight when hanging from geostationary orbit down to earth, 36000 km below. That is a very ...

Back in the late 1970s, Arthur C. Clarke caused a stir when he brought to the public’s attention the idea of a space elevator: a much easier, cheaper, faster and convenient way to defeat Earth’s ...

The push for a space elevator took a step forward this week when a team of researchers from Shizuoka University in Japan announced that they will launch an experiment to the International Space ...

Space-elevator tech, a longtime sci-fi staple, is about to get a test here in the real world. The Japanese STARS-Me (Space Tethered Autonomous Robotic Satellite-Mini Elevator) payload arrived at the ...

Forget buying a stairway to heaven. Serious people are trying to build an elevator to space. That’s not a metaphor, and yes, a space elevator sounds like plot point from an Arthur C. Clarke novel.

Well, Einstein’s done it again! That is to say, the gravitational theories of Albert Einstein have once again been confirmed, and to a new degree of precision. The equations of general relativity ...

elevator is built, but the weight penalty of the associated cooling systems may make them quite impracticable. It would be marvellous, of course, if our superstrength material was also a ...
