Rendezvous
The process of two or more spacecraft meeting and matching velocities in space, often for docking or proximity operations.
TECHNICAL DEFINITION
Rendezvous is an astrodynamic maneuver where two or more spacecraft are brought into close proximity and matched velocities in orbit, enabling docking, crew transfer, resupply, or satellite servicing operations, requiring precise orbital mechanics and propulsion.
BACKGROUND
The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the United States' civil space program, as well as research in aeronautics and space. Headquartered in Washington, D.C., NASA operates ten field centers across the US and is organized into three mission directorates: Human Spaceflight, Research and Technology, and Science. Established in 1958 amid the Space Race, NASA succeeded the National Advisory Committee for Aeronautics (NACA) to give the US space program a distinct civilian orientation focused on peaceful applications. Since then, it has led most American spaceflight programs, including Project Mercury, Project Gemini, the Apollo program, Skylab, the Space Shuttle, the International Space Station (ISS), and the ongoing multi-national Artemis program.

USAGE NOTE
The International Space Station relies on regular rendezvous missions for crew rotation and cargo delivery.
DEVELOPERS
Organizations developing technology related to Rendezvous.
Develops and operates Dragon spacecraft for cargo and crew transport to the International Space Station, relying on autonomous rendezvous and docking. Also developing Starship, which will require in-orbit refueling through rendezvous.
Developed the Mission Extension Vehicle (MEV) and Mission Robotic Vehicle (MRV) for on-orbit satellite servicing, which require precise rendezvous and docking capabilities.
Specializes in on-orbit servicing, active debris removal, and in-situ space situational awareness, all of which depend heavily on sophisticated rendezvous and proximity operations technologies.
Has a long history of developing and implementing rendezvous and docking procedures for human spaceflight missions (Apollo, Space Shuttle, ISS) and continues to research advanced autonomous rendezvous for future deep space exploration (e.g., Lunar Gateway).
Managed the Automated Transfer Vehicle (ATV) for cargo delivery to the ISS, which featured autonomous rendezvous and docking. Continues to develop rendezvous capabilities for future orbital infrastructure and exploration missions.
Focuses on developing a fueling infrastructure in space, providing satellite refueling services that necessitate robust and standardized rendezvous and docking mechanisms.
Developing robotic technologies for on-orbit servicing, assembly, and manufacturing (OSAM) missions, which require precise rendezvous, capture, and manipulation of spacecraft.
Developed the H-II Transfer Vehicle (HTV) for cargo resupply to the ISS, which utilized rendezvous and grappling by the station's robotic arm. Actively researching future in-orbit servicing and debris removal concepts.
