Canadarm2
Canadarm2 is an 18-metre long robotic arm of the International Space Station. It is used for undertaking maintenance works and “catching” visiting spacecraft. It was developed by the Canada Space Agency for the ISS. It is operated either by astronauts in the ISS or by ground team in the Canada Space Agency or NASA.
The arm recently suffered a minor damage because of a piece of orbital debris in the space. This debris was too small to be tracked by the ISS, which monitors objects that are softball sized or bigger for potential collision. While the impact has left a hole on this arm, its performance remains unaffected.
