Autonomous Rendezvous And Docking
Autonomous Rendezvous and Docking (AR&D) is a spaceflight operation where a spacecraft approaches and attaches to another spacecraft or space station without human intervention. AR&D systems use sensors, algorithms, and propulsion systems to navigate and maneuver the spacecraft to the target. The process involves several stages, including target identification, approach, and final docking. AR&D is critical for space exploration missions, as it enables spacecraft to refuel, repair, and exchange crew and equipment without the need for human intervention. AR&D systems have been used in several space missions, including the International Space Station, the Hubble Space Telescope, and the Mars Reconnaissance Orbiter.
