Orbital context

LROC imagery of the Apollo 16 landing zone

LRO narrow-angle camera products georeference hardware and surface disturbance at the published coordinates for Descartes Highlands. Featured-site pages and catalogue links below point to the same releases cited on the Evidence page. All six Apollo sites from orbit lists every crewed zone with LROC featured links in one table.

LROC coverage of the landing ellipse

Featured-site pages and NAC strips resolve the LM, ALSEP, and rover tracks in highland regolith.

Orbital SIM bay context

Mattingly’s instrument suite provides independent orbital mapping that frames surface geology objectives.

Highlands sample suite

Returned mass and thin-section petrology are published in open literature with chain-of-custody from mission rules.

Common questions about evidence for this landing

Factual shortcuts—full citations sit in the sections above and in mission source links.

What do LRO and LROC images show at Descartes Highlands?
Published Lunar Reconnaissance Orbiter Camera (LROC) narrow-angle products resolve hardware, experiments, and regolith disturbance at the selenographic coordinates on this page. Use the orbital section above and the official LROC / NASA links under “Official sources” for the featured-site and data-product pages for Apollo 16.
Where can I read how this evidence fits the wider Apollo record?
The How we know page summarizes independent lines of proof. The Evidence catalogue groups LRO imagery, hardware, LLR, photo comparisons, and NASA documents with primary links.
