This NASA image shows a view of the Remote Manipulator System (RMS) over an Earth's limb with a solar starburst pattern behind it. It was taken from Space Shuttle Endeavour during mission STS-77 in 1996. The Remote Manipulator System (RMS), also known as Canada Arm, was used on the Space Shuttle orbiters to deploy, maneuver, and capture payloads. It became an invaluable tool during the five servicing missions to the Hubble Space Telescope. Astronauts were able to capture the giant telescope and then place it back into orbit once the servicing mission was complete.
