Enos was the second chimpanzee launched into space by NASA. He was the first chimpanzee, and third hominid after cosmonauts Yuri Gagarin and Gherman Titov, to achieve Earth orbit. Enos's flight occurred on November 29, 1961. This is a patch commemorating his spaceflight. It is 4" wide.
Ham the Astro Chimp was launched on a sub-orbital flight on January 31, 1961 atop a Mercury-Redstone rocket as part of Project Mercury. The name “Ham” was given to the chimpanzee only after his successful mission. NASA was concerned with the potential of bad publicity surrounding the possibility of a failed mission with a named chimp on board, so until after his mission, Ham was known as “No. 65” and among his handlers, he was known as “Chop Chop Chang”.
The Apollo-Saturn 201 (AS-201) mission was an unmanned suborbital flight to test the Saturn IB launch vehicle and the Apollo Command and Service Modules. It was the first flight of the two-stage Saturn IB. The objectives of the flight were to verify the structural integrity, launch loads, stage separation, and operation of subsystems of the Saturn 1B, and evaluate the Apollo spacecraft subsystems, heatshield, and mission support facilities. The patch depicts the Saturn IB rising atop a column of fire and smoke and the Command Module re-entering the atmosphere.
