Apollo lunar-module astronauts stood side by side only 16 inches apart, viewing the lunar surface through two two-square-foot windows.
Notes on verification
Core design facts (standing astronauts, two ~2-sq-ft windows, field-of-view rationale) are confirmed by independent NASA and technical sources. The specific '16 inches apart' figure traces to a single original source (Smithsonian/airspacemag, same author) and lacks independent corroboration, though it is plausible given cabin dimensions.
