==== Gemini 5 ====
On February 8, 1965, Armstrong and Elliot See were picked as the backup crew for [[Gemini 5]], with Armstrong as commander, supporting the prime crew of [[Gordon Cooper]] and [[Pete Conrad]].{{sfn|Reichl|2016|p=78}} The mission's purpose was to practice [[space rendezvous]] and to develop procedures and equipment for a seven-day flight, all of which would be required for a mission to the Moon. With two other flights ([[Gemini 3]] and [[Gemini 4]]) in preparation, six crews were competing for simulator time, so Gemini{{nbsp}}5 was postponed. It finally lifted off on August 21.{{sfn|Hacker|Grimwood|2010|pp=255–256}} Armstrong and See watched the launch at [[Cape Kennedy]], then flew to the [[Manned Spacecraft Center]] (MSC) in Houston.{{sfn|Hansen|2005|p=239}} The mission was generally successful, despite a problem with the [[fuel cell]]s that prevented a rendezvous. Cooper and Conrad practiced a "phantom rendezvous", carrying out the maneuver without a target.{{sfn|Hacker|Grimwood|2010|pp=257–258}}
