sqorbit writes: Sixty years ago, the space race was in full swing. Russia had sent Sputnik into space with much success. In an effort to push farther, they rushed sending a dog into space in a re-purposed Sputnik rocket. The mission launched with no clear solution to a safe re-entry. Within a few hours of launch, temperature controls failed, killing the female dog named Laika. Launched on November 3, 1957, it did not re-enter the earth's atmosphere until April 14, 1958. Laika was the first living creature to fly into orbit, Space.com reports. While Soviet publications at the time claimed that Laika died, painlessly, after a week in Earth's orbit, Anatoly Zak of RussianSpaceWeb.com writes that several Russian sources revealed decades later that the dog actually survived in orbit for four days and then died when the cabin overheated. "According to other sources, severe overheating and the death of the dog occurred only five or six hours into the mission," he writes. "With all systems dead, the spacecraft continued circling the Earth until April 14, 1958, when it re-entered the atmosphere after 2,570 orbits (2,370 orbits according to other sources) or 162 days in space. Many people reportedly saw a fiery trail of Sputnik 2 as it flew over New York and reached the Amazon region in just 10 minutes during its re-entry."
