Space 'spiders' could build solar satellites

A mission to determine whether spider-like robots could construct complex structures in space is set to launch in January 2006. The spider bots could build large structures by crawling over a "web" released from a larger spacecraft.


The engineers behind the project hope the robots will eventually be used to construct colossal solar panels for satellites that will transmit solar energy back to Earth. The satellites could reflect and concentrate the Sun's rays to a receiving station on Earth or perhaps beam energy down in the form of microwaves.


The Japanese Aerospace Exploration Agency will launch a satellite called Furoshiki on 18 January 2006, which will conduct three experiments to test the idea. The satellite will be deployed from a rocket on a sub-orbital trajectory. This means scientists will have only 10 minutes of microgravity in which to perform their tests before the craft starts its descent back to Earth and eventually burns up in the atmosphere.


The first experiment will see three small satellites detach from the mother ship and stretch out to form two corners of a triangular net with their mother craft forming the other. Onboard cameras will be used to verify that the net, which measures 40 metres on each side, remains as steady as possible and that the daughter satellites do not get tangled in the web.
