ISS' Robotic Arm Damaged After Getting Hit By Orbital Debris

An important part of the International Space Station (ISS) been damaged after getting hit by orbital debris. The damage doesn't appear to be substantial, but it shows the threat posed by such "junk." The damage was discovered during an inspection of the ISS' Canadarm2 on May 12, the Canadian Space Agency (CSA) said in a statement. Canadarm2 is the CSA's contribution to the ISS and is essentially a robotic arm that performs various important tasks, from moving supplies and even astronauts to grabbing visiting vehicles then berthing them to the ISS. Images of the hit show small damage, but it was quite a "lucky strike," considering that Canadarm2 only has a diameter of 14 inches.
