This jointed robotic arm, known as the Canadarm or Remote Manipulator System arm was used to move payloads and position astronauts working outside the Space Shuttle or International Space Station. This Canadarm flew on 15 missions and four orbiters from 1994 through 2011, including Discovery’s last six missions, all to the International Space Station.
The Canadarm is in the James S. McDonnell Space Hangar under the shuttle Discovery. More details about the Canadarm are located on its label which is on the main floor in the Space Hangar. Find it for yourself in our Google Expedition!
