The Dog Star, Laika has become the first creature to visit the orbit after sixty years. Still animals are being in to the orbit, while scientists are now sending much smaller animals. The chief scientist, Julie Robinson from the International Space Station project has explained about the experience learned by sending animals to orbit.
Around three and half years, Yuri Gagarin, a Russian cosmonaut became the first human to visit the outer galaxy, when his spacecraft, Vostok completed earth’s orbit on 12th April, 1961. Since, Laika was sent in 1957 and became the first living critter to travel an orbit of earth.
Albert I, a rhesus monkey was first mammal sent in June 1948 to space via rocket for the NASA’s mission with the aim of testing its respond to weightlessness. Albert reached 39 miles (i.e. 63 Km) in altitude, little down the beginning of the outer space at hundred kilometers.
However, Dezikin and Tsygan were the first dogs sent in August 1951 in to the space for the sub-orbital journey for the Soviets and returned alive.
a Russian biologist and proud scientist, who pioneered the role to train Laika and more other earlier space animals, 90-year-old Adilya Kotovskaya said that, “I asked her to forgive us and I even cried as I stroked her for the last time. Those nine orbits of Earth made Laika the world’s first cosmonaut—sacrificed for the sake of the success of future space mission. We chose bitches because they don’t have to raise a leg to urinate which means they need less space than the males.”
