weightlessness. 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.2On June 11, 1948, a V-2 Blossom launched into space from White Sands, New Mexico carrying Albert I, a rhesus monkey. Lack of fanfare and documentation made Albert an unsung hero of animal astronauts. 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. The monkey died on impact. 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 December 12, 1949, the last V-2 monkey flight was launched at White Sands. Albert IV, a rhesus monkey attached to monitoring instruments, was the payload. It was a successful flight, with no ill effects on the monkey until impact, when it died.3The Soviets kept close tabs on what the U.S. was doing with their V-2 and Aerobee missile projects during the early 1950's. Basing their experiments on American biomedical research, Soviet rocket pioneer Sergei Korolev, his biomedical expert Vladimir Yazdovsky, and a small team used mice, rats and rabbits as one-way passengers for their initial tests. They needed to gather data to design a cabin to carry a human being into space. Eventually they chose small dogs for this phase of testing. Dogs were chosen over monkeys because it was felt that they would be less fidgety in flight. A test with two dogs would allow for more accurate results. They chose females because of the relative ease of controlling waste.4On August 15, 1951, Dezik and Tsygan ("Gypsy") were launched. These two were the first canine suborbital astronauts. They were successfully retrieved. In early September 1951, Dezik and Lisa were launched. This second early Russian dog flight was unsuccessful. The dogs died but a data recorder survived. Korolev was devastated by the loss of these dogs. Shortly afterwards, Smelaya ("Bold") and Malyshka ("Little One") were launched. Smelaya ran off the day before the launch. The crew was worried that wolves that lived nearby would eat her. She returned a day later and the test flight resumed successfully. The fourth test launch was a failure, with two dog fatalities. However, in the same month, the fifth test launch of two dogs was successful. On September 15, 1951, the sixth of the two-dog launches occurred. One of the two dogs, Bobik, escaped and a replacement was found near the local canteen. She was a mutt, given the name ZIB, the Russian acronym for "Substitute for Missing Dog Bobik." The two dogs reached 100 kilometers and returned successfully. Other dogs associated with this series of flights included Albina ("Whitey"), Dymka ("Smoky"), Modnista ("Fashionable"), and Kozyavka ("Gnat").5Sam, a rhesus monkey, was one of the most well known monkeys of the space program. His name was an acronym for the U.S. Air Force School of Aviation Medicine at
