NASA astronaut Neil Armstrong, prime crew Command pilot on Gemini 8, climbs into a full-scale model of the Gemini spacecraft during water egress training on the Gulf of Mexico in January 15, 1966. March 16, 2016 marks the 50th anniversary of NASA's Gemini 8 mission, the sixth manned spaceflight conducted during the United States' Project Gemini program. The primary objective of the mission, the successful docking of two spacecraft in orbit, a first in spaceflight, was a success though the crew would experience a critical in-space system failure, forcing them to abandon the mission prematurely.
