Sample explorer — the 53 returned samples
Apollo 11 returned ~21 kg of rock and soil in 53 numbered samples. Filter by family, sort by clicking a column, or search by number or text. Mass and classification are from the Preliminary Science Report; the “notable” notes are the verified highlights from the Lunar Sample Compendium.
