Albert was anesthetized during flight and implanted with sensors to measure his vital signs but died upon impact at re-entry. The first mammal in space was Albert II, a rhesus monkey launched by NASA who reached an altitude of 83 miles (134 km) on June 14, 1949. In 3 minutes and 10 seconds of flight, the fruit flies reached an altitude of 68 miles. 20, 1947, the United States put fruit flies aboard captured German V-2 rockets to study radiation exposure at high altitudes. The first animals to reach space - not counting any bacteria that may have hitched a ride on previous rockets - were fruit flies.

Laika was, however, the first living being to reach orbit around Earth after her launch on Nov. Despite her fame, Laika was not the first animal in space NASA and the Soviet Union had been launching animals for about a decade by the time she flew.
