Orbital repair refers to the process of fixing or maintaining spacecraft while they are in orbit around Earth or other celestial bodies. This can involve repairing damaged components, replacing parts, or performing upgrades to ensure the spacecraft continues to function effectively. Techniques used in orbital repair can include robotic systems or astronauts conducting repairs during spacewalks. One notable example of orbital repair is the servicing missions conducted on the Hubble Space Telescope. These missions involved astronauts traveling to the telescope to replace instruments and make necessary repairs, significantly extending its operational life and enhancing its scientific capabilities.
