Desert RATS in Arizona Rehearse Asteroid Sojourn

摘要

A robot on the international space station has completed a job that until now has been possible only with spacesuit-clad astronauts conducting spacewalks. On Aug. 29, the $200 million Canadian-built Dextre robot successfully removed a broken circuit-breaker box from the outside of the orbiting laboratory and replaced it with a new one. The box, called a Remote Power Control Module, controls the flow of electricity through the station's secondary power distribution system.
