An orbiting robot developed by the Canadian Space Agency (CSA) has successfully refueled a mock satellite using a NASA-built module in a mission aboard the International Space Station (ISS). The achievement represents an important step towards extending the lifespans of both new and existing satellites, which can become extremely restricted once they run out of propellant fuel.
Known as Dextre, the robot works in conjunction with NASA's Robot Refueling Mission (RRM) module, using a pair of mechanical arms to manipulate the satellite. As the name implies, it's capable of fine-grained movement, cutting wires and removing relatively small safety caps to get to the fuel tank — a video of the module's final withdrawal from the tank can be...
