On October 27, 1960, one of the most significant events in the history of animal behavior research took place. A chimpanzee named Enos became the first chimpanzee to orbit the Earth, paving the way for human spaceflight.
Enos was born at the Miami Rare Bird Farm in 1958 and was purchased by the United States Air Force for $1,000. He underwent extensive training for his space mission at Holloman Air Force Base in New Mexico, learning to perform tasks and respond to stimuli while in a Mercury capsule simulator.
On the historic day, Enos was strapped into a custom-fitted couch inside a Mercury-Atlas 5 capsule, which was launched from Cape Canaveral, Florida. The capsule orbited the Earth twice at an altitude of about 100 miles and a speed of 17,000 miles per hour. During the flight, Enos performed various tasks, such as pulling levers in response to flashing lights, demonstrating that complex tasks could be performed in space.
Although the mission was planned for three orbits, it was cut short due to a malfunctioning thruster and the capsule's overheating. After a flight lasting 1 hour and 28 minutes, the capsule splashed down in the Atlantic Ocean, and Enos was recovered by a rescue team. He survived the mission in good health and lived until 1962 at Holloman Air Force Base.
Enos' successful mission was a crucial step in the Mercury program, which aimed to put an American astronaut into orbit. The data collected from his flight helped NASA scientists better understand the effects of spaceflight on living beings and make necessary adjustments for future human missions. Less than a year after Enos' flight, on February 20, 1962, John Glenn became the first American to orbit the Earth, marking another milestone in the history of space exploration.
Today, Enos is remembered as a pioneer in the field of space research and a symbol of the important role animals have played in advancing scientific knowledge.
