man invented the airplane to touch the sky and then built the spacecraft in an attempt to measure the infinite depths of space.
Man did not stop here. Now he had to see what was there in space? He had already sent an unmanned spacecraft, but before taking the risk of sending humans there.it was decided to send a dog into space as a living creature. On November 3, 1957, the then Soviet Union sent a bitch named Laika into space, who was the first living creature to cross the blue sky.
