The moonwalk
The two hours and thirty-one minutes on the surface — the event the whole library orbits, gathered here as one chapter: the suits and backpacks that made the crew self-contained, the cabin egress mechanics, how it felt to move in 1/6 g, the prioritized surface tasks (contingency sample first, then the flag, the TV, the experiments, and the rock boxes), and the contingency procedures held in reserve. This map draws on the operational sources — the Lunar Surface Operations Plan (what the crew would do outside) and the EVA Procedures (Final) (the cabin checklist and the failure cases) — and on the crew’s own retrospective in the Technical Crew Debriefing (what actually happened). The official Mission Report adds the consolidated outcome (~47 lb of samples, the planned-vs-actual timeline). For the descent that put the crew on the surface and the ascent that brought them off it, see Flight operations.
Concepts
Section titled “Concepts”- Apollo 11 EVA (first moonwalk) — “one small step” and the prioritized surface tasks.
- Apollo 11 EVA planned vs. actual timeline — Mission Report Table 11-I: per-task planned vs. actual times, the prep overrun, and the documented-sample cut.
- Apollo 11 EVA life-support and mobility equipment — PGA, PLSS, OPS, LEC, and the egress/jettison sequence.
- Lunar surface mobility in one-sixth gravity — the lope, balance, traction, and EVA workload.
- Apollo 11 contingency EVA procedures — one-man EVA, PLSS recharge, repress failure, and orbital transfer EVA.
- Crew health and biomedical performance on Apollo 11 — EVA metabolic findings (Aldrin’s program-high rate), the lost rest period, and the minor medical events.
- Lunar dust as an operational problem — blowing dust at landing, the “chimney sweeps” cabin grit, the dust detector, and the dust-killed Lunakhod reflector.
- Ceremonial and symbolic surface activities — the plaque, the flag, and the call from the President.
- Lunar sample collection and containers — the contingency/bulk/documented sampling carried out during the EVA.
- Apollo 11 sampling tools and containers — the hand tools and containers the crew used to collect and seal the samples.
- Lunar field geology (Experiment S-059) — the in-situ geologic observations and documented sampling.
- Television broadcast and surface communications — the slow-scan TV camera, the S-band link, and the MSFN dishes that carried the moonwalk to Earth.
- Apollo 11 surface photography — the Hasselblad, 16-mm sequence, and close-up stereo cameras and their record.
- Apollo 11 photographic index — the magazine-and-frame catalog of the returned imagery.
- LROC imaging of the Apollo 11 landing site — the traverse trails the moonwalk left on the ground, seen from orbit.
