Earth landing as recorded in the reviewed NASA clock source. NASA prints actual launch 07:45 EDT and landing 03:56 EDT without seconds; stored zero seconds mark the agreed minute boundaries. Wikipedia’s landing seconds differ from the duration-implied NASA value, so no exact second is asserted. This flown 1993 mission is distinct from the 1985 lettered STS-51 series and the earlier scrubbed attempts.
