I've adjusted tagging on a few questions so that stage-separation appears on questions about separation events involving
- stages
- capsules
- "pseudo-stages" like Apollo command and service modules
and separation appears on questions about other kinds of separation events, including things like
- boosters
- fuel tanks
- fairings
- parachutes
But the appropriate space words needed to define these two in their wiki excerpt escape me.
What might clear, concise, accurate† and exclusive definitions for these two tags be?
† while the distance between two nearby spacecraft can be called the separation, the event itself is called a conjunction.
