Rank 6 documents Vostok 1 — the mission that made Yuri Gagarin the first human to orbit Earth and proved crewed spaceflight was no longer science fiction. Launched from Baikonur on a Vostok-K rocket derived from the R-7 ICBM family, the spherical Vostok capsule completed a single 181 × 327 km orbit in 108 minutes before Gagarin ejected and parachuted to the steppe — a procedure kept secret until later missions. OKB-1 under Sergei Korolev had already placed Sputnik in orbit; Vostok 1 translated that engineering triumph into a human story the world could not ignore. The plate's hatched linocut capsule hero, dense text archive panel, and Soviet Space Program emblem capture Wallimilist International Space grammar — deep navy paper, cream slab typography, mission-accurate spec tables, and constructivist museum discipline without NASA stipple tropes. Curator copy ties Gagarin to the broader 1961 Space Race moment when Soviet hardware reached orbit first and the West scrambled to answer.
