Space spiders, small robots able to crawl along mesh webbing, will be tested during a joint mission with the Japanese Aerospace Exploration Agency, the European Space Agency and the Vienna University of Technology. Two small spider bots, RobySpace Junior 1 and 2, will climb out of a mother satellite and crawl along a net towards daughter satellites. Nearly 30 years ago, Arthur C. Clarke wrote about a spider used to test the cables of a space elevator in The Fountains of Paradise.
