Before her flight, Belka underwent rigorous training. This included being confined to small boxes for long periods, enduring high G-forces in centrifuges, and learning to wear specialized space suits. The goal was to simulate every possible stressor of spaceflight to ensure the canine passengers wouldn't panic. The Mission: Sputnik 5 Observations during the flight provided vital data

Belka was selected based on her calm temperament, small size (necessary for the cramped Vostok capsule), and physical endurance. Return and Legacy Before her flight, Belka underwent
