Which dog went into space with Laika? - in detail
The first dog to orbit Earth was a small mixed-breed named Laika. She was launched on board Sputnik 2, the Soviet Union's second artificial satellite, on November 3, 1957. Laika's mission was designed as a test of the spacecraft and its equipment, with the expectation that she would not survive the journey. Sadly, this prediction proved true; Laika died several hours into her flight due to overheating in the cabin. However, her sacrifice played a crucial role in advancing space exploration, paving the way for future missions involving both animals and humans.
