In 1959, the U.S. needed a Cold War win and the country was eyeing spaceflight. And so a pair of mismatched monkeys found themselves bundled up and placed in a Jupiter missile. Dubbed Able and Baker, they became the first primates to survive spaceflight during a suborbital predawn flight on May 28, 1959.
Their survival made them instant celebrities, although spaceflight was not the most dramatic part of their stories. To announce their successful flight, NASA unveiled Able and Baker to journalists in the same room where just a month prior they had introduced the Mercury 7 as the country's first human astronaut candidates.
Here, Baker, who was a squirrel monkey, poses with a model of the Jupiter rocket she and Able flew.
Able was a rhesus monkey. Along with Baker, she became one of the first two primates to survive a spaceflight. During their flight, they reached an altitude of about 300 miles (480 kilometers).
Baker, the squirrel monkey that was the other first primate to survive spaceflight. She and Able were preceded by plenty of attempts at sending monkeys to space, including six consecutive Alberts who were all killed by assorted spaceflight hazards.
Baker tested out capsules like the one that would carry her to space as early as four weeks before the flight itself.
Able also had a specially built capsule for the flight. Each capsule, which is sometimes referred to as a couch, kept the monkey contained and included sensors to monitor their spaceflight experience.

After their spaceflight, Able and Baker were fished out of the Caribbean by the U.S.S. Kiowa. Here, Able is seen on board that ship as caretakers check her health.
After the U.S.S. Kiowa confirmed the two monkeys were healthy, personnel telegraphed the news back to land. The government had been desperate for any win in the space race, and Able and Baker's safe flight served as just that.
During a news conference held after the two monkeys survived their flight, on June 1, 1959, journalists meet Baker, on the left, and Able, on the right.

The monkeys were unveiled in the same room where NASA had first introduced Alan Shepard, John Glenn and the other Mercury 7 astronauts as their first human candidates for spaceflight just a month before.

After the news conference, the monkeys' caretakers noticed that one of Able's three electrode sites seemed to be infected. They prepared for a routine surgery to remove it, but when they sprayed Able with a standard anesthetic, she stopped breathing. Doctors spent 2 hours trying to rescue her, including performing mouth-to-mouth resuscitation. She didn't survive; her body was taxidermied and sent to the Smithsonian National Air and Space Museum in Washington, D.C.
Baker lived to reach 27, which is extreme old age for a squirrel monkey. During her later years, she lived at the Alabama Space and Rocket Center, where she stayed in an enclosure labeled "The First Lady in Space." Her remains are buried on site and marked with a large marble headstone.
