When Japan launches its unmanned freighter to ISS on September 10, it will carry a two-cubesat engineering test of some of the concepts required to build a space elevator.
In the experiment, which will be the first of its kind in space, two ultrasmall cubic satellites, or “cubesats,” will be released into space from the station. They will be connected by a steel cable, where a small container — acting like an elevator car — will move along the cable using its own motor. A camera attached to the satellites will record the movements of the container in space, according to the Japanese newspaper The Mainichi.
Each cubesat measures just under 4 inches (10 centimeters) on each side. The cubesats will be connected by a 33-foot-long (10 meters) steel cable for the “elevator car” to move along, according to the report.
I wonder if this experiment will also test some of the technology needed for generating electricity using a tether. Over the decades there have been a number of experimental attempts in space of this concept, all of which have failed for a variety of reasons, all unrelated to the concept itself.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
