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 records actual launch 07:47:15 EDT and landing 06:57:19 PDT; Wikipedia’s visible clocks agree. The hidden end-date value is a next-unit boundary rather than another observed clock, so NASA’s explicit clock is adopted. The flown 1990 mission is distinct from the 1984 lettered STS-41 series and from the later orbital Ulysses deployment.
