Editing Space rendezvous (section)

===Rendezvous phases===
Space rendezvous of an active, or "chaser", spacecraft with an (assumed) passive spacecraft may be divided into several phases, and typically starts with the two spacecraft in separate orbits, typically separated by more than {{convert|10000|km|sp=us}}:<ref name=wertz2003/>

A variety of techniques may be used to effect the [[Translation (physics)|translational]] and [[rotation]]al [[Orbital maneuver|maneuvers]] necessary for proximity operations and docking.<ref name=lee2010>
