Apollo 11 Lunar Sample Compendium (sample entries)

  • Source documents: 53 per-sample PDFs in inputs/, named lunar-sample-compendium-NNNNN.pdf (full list in the tables below).

  • Original: Charles Meyer, Lunar Sample Compendium, NASA Astromaterials Research and Exploration Science (ARES), Johnson Space Center, 2009–2011 (some entries marked DRAFT). One dossier per Apollo 11 sample.

  • Available online: NASA Astromaterials (JSC) — Lunar Sample Compendium (per-sample dossiers; also mirrored at lsc.apolloinrealtime.org).

A set of 53 detailed dossiers, one per Apollo 11 sample, from NASA’s Lunar Sample Compendium — the modern, reference-grade synthesis of everything learned about each rock and soil over four decades of study. Where the 1969 Preliminary Science Report gave the first-look classification and the 1977 Information Catalogue gave the curation record, each Compendium entry compiles a sample’s petrography, mineral modes, bulk and trace chemistry, radiometric and cosmic-ray-exposure ages, magnetic/maturity data, subsample and processing history, and a guide to the literature, with photographs. Together they turn the collection from a catalogue into a worked geologic data set.

The 53 entries span the Apollo 11 number block (10002–10094) and fall into a few natural families. The mare basalts divide into two distinct high-K and low-K suites; the breccias are dominantly shock-lithified regolith breccias; and the soils include the most-studied lunar sample of all, 10084. Notable members: 10017 (973 g) is the largest rock returned; 10002 (5629 g) the largest soil (with 10084 and 10086 as splits of it); 10010 is the contingency sample; 10004/10005 are the two drive-tube cores.

  • Two basalt suites. Apollo 11 mare basalts split into a high-K group (e.g., 10017, 10057, 10072), younger at ~3.55–3.6 Gyr, and a low-K group (e.g., 10003, 10020, 10044, 10062) at ~3.7–3.85 Gyr — distinct lavas, not one fractionation series. (See Apollo 11 basalt suites.)
  • Breccias are regolith breccias. Most non-basalt rocks are shock-lithified soil — friable, agglutinate-rich, and full of solar-wind gases — rather than deep-seated lithologies.
  • The soils. 10084 is the canonical, well-characterized mature mare soil; 10002 the largest soil (10084/10086 are its splits); 10010 the contingency sample.
  • Per-sample depth. Entry length tracks study intensity — 10017 (14 pp), 10084 (11 pp), and 10057 (11 pp) are among the most-analyzed; many small breccias get 3 pp.
  • Subsample tracking. Entries record the parent/split genealogy (e.g., 10002 → 10084/10086; 10026 → 10027/10028), the basis of decades of traceable allocation.
  • Provenance is coarse. Most samples have no recorded surface position; only 10022, 10023, and 10046 have a known in-situ orientation from pre-collection photos. All were gathered within ~15 m of the LM — the disturbed-regolith zone visible around the descent stage in the LROC image.
