Astronauts Virgil I. "Gus" Grissom and John Young launched on the Gemini 3 mission on March 23, 1965. Because Grissom's Mercury spacecraft, Liberty Bell 7, had sunk at the end of his 1961 mission, he unofficially named Gemini 3 "Unsinkable Molly Brown." Gemini 3 was the first crewed mission of Project Gemini, which aimed to test long-duration missions, rendezvous and docking between two space vehicles, and EVA or "spacewalking."
Boilerplate Mercury spacecraft being manufactured "in-house" by Langley technicians. The capsules were designed to test spacecraft recovery systems. The escape tower and rocket motors shown on the completed capsule would be removed before shipping and finally assembly for launching at Wallops Island. Design of the Little Joe capsules began at Langley before McDonnell started on the design of the Mercury capsule. (Great Images in NASA)
GEMINI 2: On January 19, 1965, this capsule was launched on its first flight aboard a Titan II booster from Complex 19 at Cape Canaveral Air Force Station. The 10 minute / 2,117 nautical mile flight was the last of two unmanned missions to qualify the Gemini spacecraft and its launch vehicle for two-man orbital space flight.
