<P> A simulated Canadarm installed on the Space Shuttle Enterprise was seen when the prototype orbiter 's payload bay doors were open to test hangar facilities early in the shuttle program . The Canadarm was first tested in orbit in 1981 , on Space Shuttle Columbia 's STS - 2 mission . Its first operational use was on STS - 3 to deploy and maneuver the Plasma Diagnostics Package . Canadarm has since flown on more than 90 missions with all five orbiters . </P>
