Monkeys "Able" and "Baker" became the first monkeys to survive spaceflight after their 1959 flight. On 28 May 1959, aboard Jupiter IRBM AM-18, were a 3.18 kg American-born rhesus monkey, "Able", and a 310 g squirrel monkey from Peru, "Baker". The monkeys rode in the nosecone of the missile to an altitude of 360 miles (579 km) and a distance of 2735 km down the Atlantic Missile Range from Cape Canaveral, Florida. They withstood forces 38 times the normal pull of gravity and were weightless for about 9 minutes. A top speed of 16 000 km/h was reached during their 16 minute flight. The monkeys survived the flight in good condition. "Able" died four days after the flight from a reaction to anesthesia, while undergoing surgery to remove an infected medical electrode. "Baker" lived until 29 November 1984, at the US Space and Rocket Center in Huntsville, Alabama.
On this day in 1959, the 10 year old squirrel monkey Miss Bakerand the rhesus monkey Abel were launched on a suborbital flight aboard a US JUPITER AM-18 rocket from Cape Canaveral. The first primates in space (defined as above 50 mile altitude by the U.S. at the time) returned to earth unharmed.
Abel died three days later due to anesthesia during an operation to remove an electrode. Baker survived for a further 17 years.
Two years after this suborbital flight (on May 5, 1961), astronaut Alan Shepard took a similar trip.
