This podcast episode tells the story of Laika, a Soviet dog who became the first living being to orbit Earth in 1957. Laika was chosen from a group of stray dogs because scientists believed strays were tougher and more adaptable. She underwent rigorous training, including centrifuge simulations and exposure to loud noises and small cages.
The mission, Sputnik 2, was launched on November 3, 1957, with Laika inside a specially designed capsule equipped with life support systems. The Soviets initially claimed Laika died painlessly from oxygen depletion. However, in 2002, the truth was revealed: Laika died from overheating just hours after launch. The capsule's thermal insulation may have been damaged, and the attached rocket booster contributed to the overheating.
The episode explores the ethical questions surrounding Laika's sacrifice. Despite the tragic outcome, Laika's mission provided crucial data that paved the way for human spaceflight. The episode concludes by reflecting on Laika's legacy and the advancements in animal welfare in space exploration.
