Every visitor to the North Carolina Zoo can now learn about one of the most memorable animals in American history before they even enter the gates. On July 14, 2026, World Chimpanzee Day, the Zoo unveiled a new Historical Highway Marker honoring Ham the Astrochimp. Standing just before the Zoo’s entrance, the marker recognizes Ham’s extraordinary role in America’s early space program while also celebrating the life he later found here at the North Carolina Zoo.
Ham’s story spans continents, decades, and some of the most significant moments in both scientific and zoo history. On January 31, 1961, Ham made history when he became the first chimpanzee launched into space aboard NASA’s Mercury-Redstone 2 mission. During the flight, Ham successfully completed tasks while experiencing weightlessness. This demonstrated that living beings could survive and function in space. Ham’s mission provided critical information that helped pave the way for America’s first human spaceflight just a few months later.
At the dedication ceremony, our Curator of Mammals, Jenn Ireland invited guests to think about Ham in a different way. “Ham was only 3 ½ to 4 years old when he took his space flight,” she said. As she spoke, guests could see 3-year-old chimpanzee, Bintu, romping through the habitat with her mother. Watching Bintu offered a simple but powerful comparison. It was easier to imagine Ham, not as a symbol of the Space Race, but as a young chimpanzee just starting out in life.
Today, Ham’s story brings up complicated emotions for many people. For some, Ham is remembered as the chimpanzee who helped make human spaceflight possible. Others recognize that Ham had no choice in participating in such a dangerous mission. Both perspectives are part of Ham’s story, and it is understandable to experience conflicting feelings. His is a story of courage, discovery, and innovation, but it is also one of growth, both in how we care for chimpanzees and in how we understand our responsibility to them.

Ham’s flight took place during a very different time in history. In the decades since, our understanding of chimpanzees and their intelligence, emotions, and complex social lives has grown tremendously. Alongside that understanding, standards for animal welfare have continued to evolve. This perspective adds another layer to Ham’s place in history. We can recognize his remarkable achievement while also appreciating how much we have learned about caring for chimpanzees since then.
After completing his role in the space program, Ham spent 17 years at the Smithsonian’s National Zoo. Although well cared for, he had no contact with other chimpanzees. In the 1970s, with the growing understanding that this was not ideal for such a deeply social species, the National Zoo began searching for a new home for Ham, where he could live among other chimpanzees. During this search, the North Carolina Zoo stood out. As Curator Ireland shared during the ceremony last month, the National Zoo’s director was quoted as saying, “Of all the chimpanzee exhibits and quarters that I have visited in the United States, this offers Ham the best opportunity to become a socially integrated chimpanzee.”
Ham arrived at the North Carolina Zoo on September 25, 1980 when he was around 23 years old. Here, he joined a troop of 6 chimpanzees and formed a particularly close bond with one named Maggie. After years without other chimpanzees, Ham finally had the opportunity to live as part of a social group. It was a turning point, not only in Ham’s life, but also in the Zoo’s history. Curator Ireland reflected on that connection during the ceremony, “While I never had the honor to know Ham, I had the privilege to work for many years with the Zoo’s original chimpanzees: Maggie, Ruthie, Hondo, Koby, Terry, and Betty, and like Ham, my favorite chimpanzee was Maggie. She was the last of the group to pass away in 2019.”
Ham passed away on January 17, 1984. His time with us was relatively short, but the impact of his arrival continues more than four decades later. Ham’s time here marked the beginning of a new chapter for chimpanzee care at the North Carolina Zoo. Since then, the Zoo has helped make advances in chimpanzee care and welfare while serving in leadership roles within the Association of Zoos and Aquariums’ Chimpanzee Species Survival Plan. As Curator Ireland concluded in her speech, “The North Carolina Zoo has been recognized as a leader in chimpanzee husbandry and management for decades, and it all started with Ham and his opportunity to become not only a national hero, but a true chimpanzee.”
Dedicating this historical marker on World Chimpanzee Day is a fitting reminder that Ham’s story is connected not only to the past, but also to the future. Deputy Director and Chief Mission officer Dr. Rich Bergl reminded guests that the Zoo’s responsibility extends beyond caring for the chimpanzees who live here. “While Ham still inspires us and our guests, we also take our responsibility to his species very seriously,” Dr. Bergl said. “We ensure that his cousins who are with us here have good lives and that his more distant relatives who remain in Africa have a future.”
The North Carolina Zoo has been partnering with communities in Uganda for over 20 years to help protect wildlife, improve conservation education, and encourage sustainable practices that benefit both people and chimpanzees. These efforts are just one example of how the Zoo is working to ensure that wild chimpanzees continue to thrive for generations to come.
The new highway marker tells the story of a chimpanzee who helped make human spaceflight possible, but it also tells a story of progress. Progress in science, progress in animal care, and progress in our understanding of one of our closest living relatives. Ham’s life cannot be separated from the era in which he lived. It reminds us that history is often complex. We can honor a remarkable achievement, acknowledge the difficult choices that accompanied it, and continue striving to do better as our knowledge grows. Perhaps that is Ham’s greatest legacy - not simply that he helped humans reach space, but that his life helped inspire decades of progress in chimpanzee care, welfare, and conservation.
Now, as visitors pass his marker and begin their journey through our park, they are reminded that Ham’s story did not end with a splashdown in the Atlantic Ocean. Some of his most meaningful chapters were written here: in a troop of fellow chimpanzees, with the people dedicated to their care, and in the ongoing work to protect chimpanzees in the wild.
