Yorick got a fair amount of press as the first monkey to live through a space flight. On September 20, 1951, a monkey named Yorick and 11 mice were recovered after an Aerobee missile flight of 236,000 feet at Holloman Air Force Base, New Mexico. It was a successful flight, with no ill effects on the monkey until impact, when it died. Albert IV, a rhesus monkey attached to monitoring instruments, was the payload.

On December 12, 1949, the last V-2 monkey flight was launched at White Sands.

On August 31, 1950, another V-2 was launched and carried an unanaesthetized mouse that was photographed in flight and did not survive impact. On June 14, 1949, a second V-2 flight carrying a live Air Force Aeromedical Laboratory monkey, Albert II, attained an altitude of 83 miles. Lack of fanfare and documentation made Albert an unsung hero of animal astronauts. On June 11, 1948, a V-2 Blossom launched into space from White Sands, New Mexico carrying Albert I, a rhesus monkey. American and Russian scientists utilized animals - mainly monkeys, chimps and dogs - in order to test each country's ability to launch a living organism into space and bring it back alive and unharmed. For several years, there had been a serious debate among scientists about the effects of prolonged weightlessness.

Before humans actually went into space, one of the prevailing theories of the perils of space flight was that humans might not be able to survive long periods of weightlessness.
