Gemini 3 primary goal was to test the new, maneuverable spacecraft. At the end of the first orbit, over Corpus Christi, Texas, Grissom effected the first orbital maneuver which lowered the orbit to a near-circular 158 x 169 kms. This was the first orbital maneuver made by any manned spacecraft.
Gemini 3 achieved a number of "firsts" in space flight. Three "first" were documented on this cover, a Beck rubber stamp cachet applied at left and autopen signatures of both astronauts.
