Synthesis
All three Apollo 11 crew members, Neil Armstrong, Buzz Aldrin, and Michael Collins, flew into space for the second and final time on the Apollo 11 mission in 1969. Each astronaut had previously completed one spaceflight on a Gemini mission in 1966: Armstrong on Gemini 8, Aldrin on Gemini 12, and Collins on Gemini 10. Following Apollo 11, none of the three crew members flew in space again.
There was initial disagreement among models regarding whether Apollo 11 was the second and final spaceflight for all three crew members. However, the consensus is that it represented the second and final mission for each astronaut, with Neil Armstrong, Buzz Aldrin, and Michael Collins each having undertaken one prior Gemini mission.

Yes. Apollo 11 was the second and final spaceflight for all three crew members: - Neil Armstrong: Gemini 8 in 1966, Apollo 11 in 1969 - Buzz Aldrin: Gemini 12 in 1966, Apollo 11 in 1969 - Michael Collins: Gemini 10 in 1966, Apollo 11 in 1969 None of them flew in space again after Apollo 11.

No. Two of the three crew members flew to space only once (Apollo 11 was their sole spaceflight), while one had flown previously and never flew again — so it was the final flight for all three, but not the second for all. - **Neil Armstrong**: Second and final spaceflight (previously flew on Gemini 8 in 1966). - **Buzz Aldrin**: Second and final spaceflight (previously flew on Gemini 12 in 1966). - **Michael Collins**: Second and final spaceflight (previously flew on Gemini 10 in 1966). Actually, correcting myself: all three Apollo 11 crew members had each flown one prior Gemini mission, makin…

Yes. All three—Neil Armstrong, Buzz Aldrin, and Michael Collins—had flown once before on Gemini missions (Gemini 8, Gemini 12, and Gemini 10, respectively) and made Apollo 11 their second and final spaceflight.
