In a landmark moment for space exploration, the Soviet Union launched the world’s first living creature into orbit on 3 November 1957 — a stray dog named Laika. The historic flight aboard Sputnik 2 marked a pivotal step in humanity’s race to explore space, but also sparked lasting debate over the ethics of using animals in scientific research.
A stray turned space pioneer
Laika, a small mixed-breed dog found wandering the streets of Moscow, was chosen by Soviet scientists for her calm temperament and resilience. Alongside other dogs, she underwent rigorous training to prepare for the extreme conditions of space. Ultimately, Laika was selected for the mission due to her composure in confined environments and her ability to remain still for long periods — vital traits for the cramped cabin of Sputnik 2.
A one-way mission
Unlike later space missions, Sputnik 2 was not designed for recovery. Soviet engineers knew Laika would not return to Earth alive. The spacecraft was launched less than a month after Sputnik 1’s success, under immense political pressure to maintain momentum in the space race. Officially, early Soviet reports claimed Laika survived for several days before her oxygen supply ran out. Decades later, documents revealed that she likely perished within hours of launch due to overheating.
Scientific and symbolic achievement
Despite the tragedy, Laika’s mission provided invaluable data about the effects of space travel on living organisms. Her journey paved the way for future human missions, including Yuri Gagarin’s orbital flight in 1961. The Soviet Union hailed her as a hero of science, and around the world she became a symbol of both human ambition and the moral complexities of technological progress.
Legacy and reflection
Today, Laika is remembered as a pioneer who helped open the path to human spaceflight. A monument in her honour stands near Moscow, depicting her poised atop a rocket, gazing toward the stars. Her story remains a poignant reminder that the pursuit of discovery often comes at a cost — and that courage can take many forms, even in a small dog from the streets.
