Reviewed individual mission infobox, actual crew, backup and support crew sections, named payload examples, NASA primary mission clock/site record and location coordinates. Actual flight, backup and ground support roles remain distinct. No orbital or lunar event is assigned an Earth anchor. Mission-control shift rosters and the complete experiment-contributor network are not exhaustively covered. Source clock discrepancies are stated in the individual chart qualification. Coverage describes the cited sections reviewed for this record.
