Shortly after the trans-lunar injection
maneuver that placed the Apollo spacecraft
on its trajectory towards the Moon, the
transposition and docking maneuver would
be performed. This involved an astronaut
separating the Apollo Command/Service
Module (CSM) spacecraft from the adapter
which fastened it to its launch vehicle
upper stage, turning it around, and docking
its nose to the Apollo Lunar Module (LM),
then pulling the combined spacecraft
away from the upper stage.
