- v. Present participle of overspecify.
Sorry, no etymologies found.
This book covers all the 1990's US Mars missions (which is overspecifying, there weren't any 1980's Mars mission and there weren't any non-US missions in that period excepting the failed Russian Mars 96), with a focus on searching for life (which of course dovetails with a component of most/all the missions).
As such, they require delicate balance, between overspecifying (acting as designer) and underspecifying (not acting as marketer).
