Among so many searches, Laika was found, a medium-sized mixed-breed dog.ĭespite not being easy, dogs were subjected to strong training sessions to be able to be entered in this experiment: Thus, several moscow stray dogs, in order to choose those most accustomed to suffering situations of hunger and desolation. Both the Soviet Union and the United States were in this race, in order to determine which of these two countries would enter this adventure for the first time.ĭue to the thousands of risks that were added to the hypotheses about this trip, the final decision was experiment with a dog. The first trip to space would be a very complex idea for anyone and this was something very easy for everyone involved in the project to take into account. But have we ever heard the idea of a trip to space with dogs? What were the purposes of this trip? How was it done? The journey into space is one of the most complex steps for humanity and this type of idea would have been considered impossible for a long time. 1954 – 3 November 1957) was a Soviet space dog who became one of the first animals in space, and the first animal to orbit the Earth.Many of the experiments that would have been carried out in order to determine the effects of some phenomenon about a living being would be carried out at first with the animals and is that regardless of the estimated results, the animals would be the first to experience these effects. Laika, a stray mongrel from the streets of Moscow, was selected to be the occupant of the Soviet spacecraft Sputnik 2 that was launched into low orbit on 3 November 1957. No capacity for her recovery and survival was planned, and she died of overheating or suffocation hours into the flight. Little was known about the impact of spaceflight on living creatures at the time of Laika's mission, and the technology to de-orbit had not yet been developed, so Laika's survival was never expected. Some scientists believed humans would be unable to survive the launch or the conditions of outer space, so engineers viewed flights by animals as a necessary precursor to human missions. The experiment aimed to prove that a living passenger could survive being launched into orbit and endure a micro-g environment, paving the way for human spaceflight and providing scientists with some of the first data on how living organisms react to spaceflight environments.

Laika died within hours from overheating, possibly caused by a failure of the central R-7 sustainer to separate from the payload. The true cause and time of her death were not made public until 2002 instead, it was widely reported that she died when her oxygen ran out on day six or, as the Soviet government initially claimed, she was euthanised prior to oxygen depletion. On 11 April 2008, Russian officials unveiled a monument to Laika. A small monument in her honour was built near the military research facility in Moscow that prepared Laika's flight to space. It portrayed a dog standing on top of a rocket. She also appears on the Monument to the Conquerors of Space in Moscow.Īfter the success of Sputnik 1 in October 1957, Nikita Khrushchev, the Soviet leader, wanted a spacecraft launched on 7 November 1957, the 40th anniversary of the October Revolution. Construction had already started on a more sophisticated satellite, but it would not be ready until December this satellite would later become Sputnik 3. Meeting the November deadline meant building a new craft. Khrushchev specifically wanted his engineers to deliver a "space spectacular", a mission that would repeat the triumph of Sputnik 1, stunning the world with Soviet prowess. Planners settled on an orbital flight with a dog. Soviet rocket engineers had long intended a canine orbit before attempting human spaceflight since 1951, they had lofted twelve dogs into sub-orbital space on ballistic flights, working gradually toward an orbital mission set for some time in 1958. To satisfy Khrushchev's demands, they expedited the orbital canine flight for the November launch. Īccording to Russian sources, the official decision to launch Sputnik 2 was made on 10 or 12 October, leaving less than four weeks to design and build the spacecraft.
