ASHEBORO, N.C. (NCN NEWS) — A chimpanzee that was launched into space and later lived at the North Carolina Zoo soon will be recognized with a North Carolina Highway Historical Marker.
The marker commemorating Ham the Astrochimp will be installed on Tuesday, July 14, at the roundabout at Zoo Connector (NC 159) and Zoo Parkway, near the zoo entrance in Asheboro.
Ham was the first hominid launched into space on Jan. 31, 1961. He flew a suborbital mission on the Mercury-Redstone 2 rocket, part of the U.S. space program’s Project Mercury. Ham’s name is an acronym for the laboratory that prepared him for his historic mission, the Holloman Aerospace Medical Center, located at Holloman Air Force Base in New Mexico.
Ham was selected for intensive training in 1959. Chimpanzees’ cognitive abilities and physiological similarities to humans made them ideal candidates for simulating astronaut performance. Ham’s training was designed to assess whether learned behaviors could be maintained during the stressful spaceflight conditions of acceleration and microgravity. It was essential for validating the feasibility of human-controlled operations in space.
Ham’s flight lasted approximately 16 minutes and reached an altitude of 157 miles, while achieving speeds exceeding 5,800 miles per hour. Despite experiencing unexpected g-forces and a trajectory deviation, Ham successfully executed his assigned tasks, demonstrating that cognitive and motor functions could persist in space. This outcome was instrumental in confirming the feasibility of human spaceflight, directly influencing the design and safety protocols for Alan Shepard’s mission four months later. The physiological data collected during Ham’s flight, such as heart rate, respiration, and stress responses, provided NASA with critical insights into the biological effects of space travel.
Ham’s mission occurred during the height of the Cold War, when the United States and the Soviet Union were locked in a technological rivalry known as the Space Race. The Soviets had already launched Laika, a dog, into orbit in 1957, and Yuri Gagarin would become the first human in space just months after Ham’s flight. Against this backdrop, Ham’s successful mission was not merely a scientific milestone but also a geopolitical statement, signaling American progress toward manned space exploration. His flight reassured policymakers and the public that the U.S. was closing the gap with Soviet achievements.
Following his historic flight, Ham became a symbol of scientific progress. Initially housed at the National Zoo in Washington, D.C., he later retired to the North Carolina Zoo in Asheboro, where he lived until he died in 1983. His remains were interred at the International Space Hall of Fame in Alamogordo, New Mexico, underscoring his enduring significance in aerospace history.
The Highway Historical Marker Program is a collaboration between the N.C. departments of Natural and Cultural Resources and Transportation.
