Gemini two-man program era — 2 museum-grade prints from the period. Gemini 3 opened the two-man program that bridged Mercury's solo hops and Apollo's lunar voyages. Grissom's return to flight after Liberty Bell 7's sinking carried symbolic weight — naming the capsule Molly Brown ('unsinkable') was deliberate gallows humour. Gemini 7 proved NASA could keep astronauts healthy across a two-week timeline matching a lunar round trip — a prerequisite Apollo could not skip. The Gemini 6A rendezvous on 15 December 1965, with Schirra and Stafford closing on Borman and Lovell, demonstrated station-keeping and formation flight techniques that later saved Apollo missions including the legendary Apollo 13 crisis procedures.
