Space debris punctures International Space Station's robotic arm

The International Space Station has been hit with a piece of orbital debris, leaving a sizeable hole in its 17 metre-long robotic arm. Experts from the Canadian Space Agency and Nasa found the puncture during a routine inspection of Canadarm2. The arm performs station maintenance, moves supplies – and even astronauts – and performs "cosmic catches" by grappling visiting crafts and bringing them to the ISS. The inspection, which took place on 12 May, found that the puncture came from a piece of space debris that was too small to be tracked – which accounts for rock or dust particles to flecks of paint from satellites, the CSA says. Any object the size of a football or larger can be tracked.
