Who is the dog and what did it do? - in detail
The dog in question is Laika, a stray mongrel from Moscow who became an unwitting pioneer of space exploration. In 1957, during the height of the Space Race between the Soviet Union and the United States, the Soviets were under immense pressure to achieve significant milestones in space travel. This urgency led them to consider sending a living organism into orbit as a test run for human spaceflight. Laika was selected from a group of stray dogs due to her calm demeanor and ability to withstand confinement.
On November 3, 1957, Laika was placed aboard Sputnik 2, the second artificial satellite launched by the Soviet Union. The spacecraft was equipped with basic life support systems, including a fan to circulate air and a system to monitor her vital signs. However, it lacked a re-entry mechanism, meaning that Laika's mission was effectively a one-way trip.
Laika's primary role was to test the conditions of space travel on a living organism. Scientists wanted to understand how weightlessness affected various physiological functions and whether a creature could survive in space. During her time in orbit, Laika's heart rate and body temperature were monitored, providing valuable data that would inform future missions.
Unfortunately, the mission was not without its flaws. The spacecraft overheated due to malfunctions in the thermal control system, leading to Laika's death within hours of launch. Despite this tragic outcome, the data gathered from her mission contributed significantly to subsequent advancements in space exploration. It laid the groundwork for future missions involving both animals and humans, paving the way for more sophisticated life support systems and a better understanding of how living organisms react to the harsh conditions of space.
Laika's story serves as a poignant reminder of the early challenges and sacrifices made in the pursuit of space exploration. Her legacy continues to be honored by those who recognize the significance of her contribution to science, despite the controversial nature of her mission.
