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 landing as recorded in the reviewed NASA clock source. NASA’s portrait caption prints launch 09:53:00.069 EDT while its facts table gives 09:53:00 EDT; the original fraction is retained and the agreed 09:53 minute is adopted. NASA and Wikipedia’s visible landing clocks agree on 06:45:21 EST/11:45:21 UTC, but their stated durations are inconsistent with the explicit clock pair. Wikipedia’s hidden end-date value is a next-unit boundary, not a competing observed landing clock. The explicit primary landing clock is retained with those gaps stated. The mission crosses the historical EDT-to-EST change; source offsets are validated per phase.
