"Space docking" is a term generally used to refer to the process of connecting two spacecraft or modules in outer space. However, there are a few alternatives that can be used to describe the same process. One is "berthing," which is often used to describe the docking of a spacecraft or module to a larger, stationary object such as the International Space Station. Another term is "rendezvous," which is the act of two spacecraft meeting up at a designated location. Lastly, "coupling" is a term used to describe the process of physically joining two components or parts of a spacecraft.
