Editing Saturn I SA-2 (section)

== History ==

Launch preparation for the mission began at Cape Canaveral on February 27, 1962, with the arrival of the second Saturn I launch vehicle. The only significant change made to the vehicle from the previous [[Saturn I SA-1|SA-1]] flight was the addition of extra [[slosh baffle|baffle]]s in the propellant tanks to mitigate fuel [[Slosh dynamics|sloshing]]. While no serious delays were encountered, there were several minor problems reported.<ref name="Benson1978" />

A leak was detected between the liquid oxygen dome and injector for the #4 [[H-1 (rocket engine)|H-1 rocket engine]]; while attempts were made to fix the problem, it was eventually decided to launch without replacing the engine. Minor problems were found in the guidance subsystem and service structure operations, damaged [[strain gauge]]s were found in a liquid oxygen stud and truss member, and a manhole cover on the dummy [[Centaur (rocket stage)|Centaur]] (S-V-D) third stage had to be replaced. Problems arose with two of the fueling computers, but each was repaired. Three hydraulic systems were also listed as potential problems.<ref name="Benson1978" />

Despite the issues encountered during flight preparation, none required the target launch date of April 25 to be pushed back.<ref name="Benson1978" />
