Going up! Japan to test mini ‘space elevator’

The test involves a miniature elevator stand-in—a box just six centimetres (2.4 inches) long, three centimetres wide, and three centimetres high.

If all goes well, it will provide proof of concept by moving along a 10-metre cable suspended in space between two that will keep it taut.
