ITT I attempt to name all Gemini crews and each flight's notable achievements OTTOMH, always starting with command pilot first, (co)-pilot second.
Gemini 3: Gus Grissom, John Young. First manned Gemini flight, short test duration. John Young's first (of many, six) flights.
Gemini 4: Jim McDivitt, Ed White. Second human and first American spacewalk (Ed White).
Gemini 5: Gordon Cooper, Pete Conrad. A longer flight (days), working toward Apollo-necessary endurance (a fortnight).
Gemini 7: Frank Borman, Jim Lovell. The two-week endurance flight.
Gemini 6a: Wally Schirra, Tom Stafford. Launched after Agena failure on first launch attempt, instead performing close rendezvous maneuvers with Gemini 7.
Gemini 8: Neil Armstrong, David Scott: First successful space docking (with Agena) is followed immediately by thruster malfunction, forcing emerg. abort. Armstrong's proven ability in crisis management played at least some role in his getting Apollo 11 command. Famously depicted in First Man.
Gemini 9a: Tom Stafford, Gene Cernan. Following another scrubbed launch attempt, Gemini 9a does a rendezvous with the ATDA (Augmented Target Docking Adapter), Agena-like target vehicle used only for this mission. Conical fairing failed to separate, leaving an "angry alligator" with which docking was impossible, so they did stationkeeping instead. Gene Cernan then did one EVA, and he had a horrible time with it, though he didn't say so at the time.
Gemini 10: John Young, Mike Collins. The pair catch up to and dock with their own Agena, and then re-visit Gemini 8's Agena. Collins becomes the first person to perform two seperate EVAs.
Gemini 11: Pete Conrad, Dick Gordon. The pair catch up to and dock with their own Agena, now using it to boost to an eccentric elliptical orbit-the highest human orbit in history, short of flying to the Moon. Gordon does two EVAs.
Gemini 12: Jim Lovell, Buzz Aldrin. Like above, good Agena dock and Agena boost. Aldrin first human to do three EVAs.
