Earth Limb Blue White — 6 museum-grade prints in this palette. 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. Apollo 9 answered the question Apollo 8 had deferred — could the Lunar Module operate as an independent spacecraft? Spider's flight demonstrated that the awkward gold-foil lander could separate from Gumdrop, fire its descent engine, and rendezvous again — the exact sequence Apollo 11 would need in lunar orbit. Alan Shepard's Freedom 7 flight on 5 May 1961 answered Soviet Vostok 1 with an American suborbital hop — enough to restore confidence and accelerate congressional commitment to Apollo. Shepard became the first American in space and, a decade later, walked on the Moon at Fra Mauro during Apollo 14 — the longest span between first flight and lunar surface of any astronaut until surpassed by later careers.
