The Little Joe 2 was an important test of the Mercury capsule because it was the first Little Joe animal flight, carrying the Rhesus monkey Sam (Macaca mulatta) close to the edge of space. He was sent to test the space equipment and the adverse effects of space on humans. His flight was launched December 4, 1959, at 11:15 from Wallops Island, Virginia, United States. The Little Joe 2 flew 55 miles (88 km) into space. It was recovered, with the monkey intact, in the Atlantic Ocean by USS Borie. Sam was one of a series of Monkeys in space. Sam was from the School of Aviation Medicine in San Antonio, Texas. Flight time 11 minutes 6 seconds. Payload 1,007 kg.


The boilerplate Mercury spacecraft used in the Little Joe 2 mission , is currently displayed at Airpower Park and Museum, Hampton, VA.
