As part of their training, they were confined in small boxes for 15–20 days at a time. Training ĭogs were the preferred animal for the experiments because scientists felt dogs were well suited to endure long periods of inactivity. A notable exception is Laika, the first animal to be sent into orbit, whose death during the 3 November 1957 Sputnik 2 mission was expected from its outset.

Most survived the few that died were lost mostly through technical failures, according to the parameters of the test. The number of dogs in space is smaller, as some dogs flew more than once. In this period, the Soviet Union launched missions with passenger slots for at least 57 dogs.

Report on space exploration at theguardian. There is also a plaque bearing her name at the biomedical research centre where she was trained. Laika became the name of a brand of Soviet cigarette, and a face on a monument at Star City, Moscow. Yuri Gagarin made history aboard Vostok 1 in April 1961.

Soviet scientists took note: after their heaven-sent hounds returned to Earth, they bred puppies from Strelka and gave one to Kennedy.Ī human soon followed Laika's lead.

President John F Kennedy angrily asked US scientists why the world's first pair of space dogs were called Strelka and Belka rather than Rover and Fido. Strelka and Belka went into orbit in 1960 with 40 mice, two rats and some plants, in what was by then an obvious preparation for a human launch. Laika became the most famous dog in space - US newspapers christened her Muttnik - but she was only the first. The capsule that became her coffin burned up in the atmosphere in April 1958 after 2,570 orbits. But humidity and temperature gradually increased.Īfter about five hours, the telemetry system began to fail: what happened thereafter can never be known, but Laika probably died, said Dr Dmitry Malashenkov, of Russia's Institute of Biomedical Problems. Laika was one of 10 dogs to complete a special space training course, and one of three selected by space scientists: Laika was to be the cosmonaut, Albina her understudy and Mushka the "technological dog" on which ground crew could test the satellite's life support systems.įor the first few hours after launch, Laika's heart beat normally, cabin pressure stayed steady and oxygen levels were constant. Laika (meaning "barker") went to an altitude of almost 2,000 miles aboard Sputnik 2, one month after the Soviet Union stunned the world and triggered the space race with Sputnik 1, the first object in orbit.įor the next 40 years, Kremlin chiefs allowed the rest of the world to believe that Laika lived to see the 40th anniversary of the October Revolution and then died peacefully.
