dogs to fly, on july 22, 1951, were named tsygan and dezik.space dogs would make history on november 3, 1957.on this date, just one month after the historic launch of the worlds first artificial satellite, sputnik, the soviet union shocked the world again by launching sputnik 2.this satellite contained the first living creature to travel in space, a dog named laika.laika was to have orbited

dogs belka and strelka made 18 orbits of earth and returned alive.like laika before them, they became distinguished，featured in newspapers and magazines around the world.six more orbital dog flights over the next eight months further tested the equipment necessary for humans to follow in the dogs footsteps.that historic event happened on april 12, 1961, when yuri gagarin became the first human to travel in space.the role of the space dogs had proven important in advancing the exploration of space.but, they would make one final flight.in 1966, traveling aboard the cosmos 110 satellite, the dogs
