Rank 8 documents Voskhod 2 — the mission on which Alexei Leonov became the first human to walk in space, exiting an inflatable Volga airlock for 12 minutes 9 seconds on 18 March 1965 while Pavel Belyayev piloted the Voskhod capsule. The Voskhod program modified Vostok hardware to carry multiple crew and, on this flight, an extendable airlock that let Leonov leave without depressurising the entire cabin — a trick Apollo would later refine differently. Leonov's suit inflated in vacuum, forcing an arduous re-entry to the hatch; the drama only amplified the milestone. The plate's archive-sheet layout, EVA linocut silhouette, and ledger-frame text column capture International Space constructivist grammar — low-drama 3/4 camera, technical-blueprint craft, mono-spec-plate labels. Curator copy ties Leonov to the 1965 Space Race EVA duel months before Ed White's Gemini 4 walk.
