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.
Wikipedia’s End date text template deliberately advances hidden dtend to the next unit boundary. A hidden end boundary is not an independent observed landing clock; visible clock disagreements and primary-source timing gaps remain separately qualified.
Coverage describes the cited sections reviewed for this record.

Earth launch as recorded in the reviewed NASA clock source. NASA records launch 09:57:00 EST and landing 06:35:50 PST; Wikipedia’s visible UTC values agree. Its hidden end-date value encodes the next-unit boundary, not another observed landing clock. The actual source clocks and historical regional offsets are retained; modern March daylight-saving rules are not projected onto 1989.
