Ever wondered if a chimpanzee has actually gone to space? Well, the answer’s yes—believe it or not. Chimpanzees were among the first animals to help us figure out what space travel might do to living creatures.
Scientists trained them to perform tasks during their flights, hoping to see how beings like us might react beyond Earth.
One chimp, Ham, really made history in 1961 when he became the first great ape in space. His quick trip proved primates could handle the wild ride of spaceflight, clearing the way for human astronauts.
Later that same year, another chimp named Enos actually orbited Earth. That’s pretty wild if you think about it.
These animal astronauts played a huge part in the early days of space exploration. Their stories give us a peek into how it all started, and honestly, it’s kind of amazing what they went through.
Ham the Chimpanzee and the Historic Space Mission
Ham the chimpanzee played a big part in one of the earliest U.S. space missions. His training and flight helped shape what came next for humans in space.
There’s a lot to unpack here—how Ham was picked, what he did on his flight, and how his mission changed Project Mercury.
How Ham Was Selected and Trained
So, how did Ham end up as the first chimpanzee in space? At first, he was just called No. 65. Out of 40 chimps tested at Holloman Air Force Base, only six—including Ham—made the training cut.
Ham started his training in 1959 at the Holloman Aerospace Medical Center. He learned to push a lever when he saw a flashing light.
The trainers put him through 219 hours of practice over 15 months. If he missed the lever, he got a small shock on his feet—ouch, but it worked. When he got it right, he earned a banana pellet.
That training mattered because Ham’s reactions were a lot like what a human might do in space. It’s pretty interesting to see how animals prepared for something so new.
Details of the Mercury-Redstone 2 Suborbital Flight
Ham blasted off on January 31, 1961, riding the Mercury-Redstone 2 mission. The whole trip lasted just over 16 minutes.
He sat strapped in his capsule, shooting up above the atmosphere. Things didn’t go totally as planned.
A valve problem made the rocket push harder than it should have. That triggered a safety rocket, and Ham ended up pulled by 17 times Earth’s gravity.
The capsule came back to Earth too fast, and Ham got hit with about 14.7 g-forces. Even with all that chaos, Ham still pushed the levers like he’d practiced.
He proved you could follow instructions even when everything’s going sideways. The USS Donner picked up his capsule after splashdown.
Ham was a bit dehydrated, but honestly, he came through in good health.
Ham’s Contributions to Project Mercury
Ham’s flight wasn’t just a test for fun—it helped NASA figure out if people could survive space. Scientists tracked his heart rate, breathing, and body temperature with sensors.
Ham’s quick lever pushes showed that basic skills still worked in space. Because he finished tasks almost as fast as he did on Earth, Ham proved it was safe enough to send humans next.
His mission gave NASA the green light to send Alan Shepard into space just a few months later. Ham really paved the way for Project Mercury astronauts.
What Happened to Ham After His Spaceflight
After his big flight, Ham got to retire. In 1963, he moved into the National Zoo in Washington, D.C.
He lived there for 17 years, and the zookeepers took good care of him. Later, Ham moved to the North Carolina Zoo in Asheboro.
He stayed there until 1983. Sadly, Ham died at age 25 from heart and liver disease.
NASA wanted to preserve his body for display, but people protested, and they changed their minds. Now, his skeleton is at the National Museum of Health and Medicine.
The rest of his remains rest at the International Space Hall of Fame in New Mexico.
Ham’s story still matters, and he opened doors for everyone who came after. If you want to dig deeper, there are plenty of detailed histories about his mission.

Legacy and Impact of Chimpanzee Space Travel
Ham’s space adventure marked a huge milestone for science and spaceflight. His mission showed that living creatures could survive space and still get things done under pressure.
His story pops up in museums, pop culture, and just about every history of space exploration.
Recognition in Science and Popular Culture
Ham proved that chimps could react quickly, even in space. That gave scientists the confidence to send humans next.
His flight set up Alan Shepard’s launch later in 1961. You’ll spot Ham in books, movies, and documentaries.
Tom Wolfe’s The Right Stuff (and the movie) includes his story, and the 2007 documentary Ham—Astrochimp #65 digs into his role in space history.
Ham’s Lasting Influence on Spaceflight
Ham’s success showed that complex tasks weren’t impossible in space. Thanks to him, NASA learned a lot about how living things handle weightlessness and heavy g-forces.
His flight helped shape early space missions and made things safer for astronauts. Without Ham’s test run, the first human spaceflights might have been a lot riskier.
He helped bridge the gap between animal research and sending people into the unknown.
Museums and Memorials Honoring Ham
If you’d like to pay tribute to Ham’s legacy, you can visit the International Space Hall of Fame in New Mexico. They’ve actually buried part of his remains there.
You’ll find his skeleton at the National Museum of Health and Medicine in Maryland. That’s a bit unusual, isn’t it?
These places really show how people keep Ham’s story alive. They highlight the way one animal changed spaceflight history and still sparks curiosity in folks who care about space and science.
