Laika [SEP] Ethics of animal testing
Due to the overshadowing issue of the Soviet versus U.S. Space Race, the ethical issues raised by this experiment went largely unaddressed for some time. As newspaper clippings from 1957 show, the press was initially focused on reporting the political perspective, while the health and retrieval—or lack thereof—of Laika only became an issue later. Sputnik 2 was not designed to be retrievable, and Laika had always been intended to die. The mission sparked a debate across the globe on the mistreatment of animals and animal testing in general to advance science. In the United Kingdom, the National Canine Defence League called on all dog owners to observe a minute's silence, while the Royal Society for the Prevention of Cruelty to Animals (RSPCA) received protests even before Radio Moscow had finished announcing the launch.
