What makes this different
Section titled “What makes this different”Built from the record
Every claim links back to the primary document it rests on — the Mission Report, the voice transcripts, the crew debriefings, the sample dossiers.
Measured against ground truth
Where the 1969 reports rounded or disagreed, the analyses re-check them against the 2011 Lunar Reconnaissance Orbiter imagery and each other.
