According to IEEE Spectrum, Canadarm has been named the 300th IEEE Milestone. The recognition focuses on the robotic arm NASA developed for its space shuttle program, a broader effort begun in the 1960s to make NASA's work more efficient and reduce costs.
The space shuttle system was designed to launch like a rocket, maneuver in Earth orbit, and land like an airplane. Canadarm's contribution was practical and significant: it could carry large satellites to and from orbit, giving the shuttle a reusable tool for handling heavy payloads in space.
