Ham The Chimp - Training and Mission

Training and Mission

Beginning in July 1959, the three-year-old chimpanzee was trained under the direction of neuroscientist Joseph V. Brady at Holloman Air Force Base Aero Medical Field Laboratory to do simple, timed tasks in response to electric lights and sounds. In his pre-flight training, Ham was taught to push a lever within five seconds of seeing a flashing blue light; failure to do so resulted in an application of positive punishment in the form of a mild electric shock to the soles of his feet, while a correct response earned him a banana pellet.

What differentiates Ham's mission from all the other primate flights to this point is that he was not merely a passenger, and the results from his test flight led directly to the mission Alan Shepard made on May 5, 1961 aboard Freedom 7.

On January 31, 1961, Ham was secured in a Project Mercury mission labeled MR-2 and launched from Cape Canaveral, Florida, on a suborbital flight. Ham had his vital signs and tasks monitored using computers on Earth. The capsule suffered a partial loss of pressure during the flight, but Ham's space suit prevented him from suffering any harm. Ham's lever-pushing performance in space was only a fraction of a second slower than on Earth, demonstrating that tasks could be performed in space. Ham's capsule splashed down in the Atlantic Ocean and was recovered by a rescue ship later that day. He only suffered a bruised nose. His flight was 16 minutes and 39 seconds long.
