There is no shortage of people interested in space, what is there? Why do people float in the air? There is no shortage of people of all ages interested in learning about space. ![Space.png](https://cdn.steemitimages.com/DQmSexHKQXUyo8aN6qRVJXLcESZy2x4xp8cE9eds7BXKj65/Space.png) ** Source** Now we always hear about human space travel. But in the beginning people were not sent there. You would be surprised to know that rats, monkeys, dogs sent into space starting from flies. Although the history of their space travel is memorable. Many have had tragic consequences. But, some came back to the earth. The first spacecraft was sent to fly. Because of, flies and humans of the genetic similarity between the cosmic radiation impact on astronauts. US scientists chose the middle. After being brought back from space, scientists found the flies alive. ![Fly.png](https://cdn.steemitimages.com/DQmZcisGMtJ4APk5ZX1sAp1bsvfMeKhKxG9zgiaAFyHVyuF/Fly.png) ** Source** Scientists send monkeys into space to find out how space travel will affect the human body. Shortly after Albert was sent into space, he suffocated to death before reaching space. So far, 32 monkeys and chimpanzees have gone into space. ![Albert.png](https://cdn.steemitimages.com/DQmNwV3VKCpghvUudUR7KUowS3MxoAKDcF3uqh8J5AsJKaE/Albert.png) ** Source** NASA recently released an extensive study of rats. Located on the International Space Station. There, the rats adapted to microgravity. The first rat traveled 137 kilometers in space in 1950. The rat died due to parachute failure. So far a few dogs have been sent into space. But LAIKA has become famous among them. And in 1957, scientists rescued this dog from a street in Moscow and sent it into space as a suitable animal. LAIKA is famous for being the first animal to orbit the universe. Although Leica never came back. He was sent with only one meal and 7 days of oxygen. But the Soviet government claimed he had lived seven days. But, according to experts, LAIKA burns with excess heat in five hours of travel. ![Laika.png](https://cdn.steemitimages.com/DQmTqLoRWXz3tFqA6NKtevGvpVSbwRwezMJ1UkystS9Kh7u/Laika.png) ** Source** In 1968, the United States and the Soviet Union competed to send someone to the moon. The Russians then sent soil and some seeds, worms and two turtles into space. In the capsule of the spacecraft JOND 5. The turtles orbit the moon and return to Earth after six days. After scientists sent the frogs into space in 1970. to understand the state of equilibrium. It found that the frogs returned to normal after 6 days. In 1973, scientists decided to send two spiders. Anita and Arbela, for their next experiment. Scientists wanted to know if they could go into space and move. It is then seen that they have been able to move in space, but less than the Earth. Fish in space, the subject seems unbelievable but true. In 1973, saltwater fish and fish eggs were sent into space. NASA sent fish into space to learn about the effects of microgravity on animals. But the fish became ill within a few days. Tardigrades or water bears sent into space in 2007. He sent on a rocket to orbit for ten days after being completely dried. ![Tardigrade.png](https://cdn.steemitimages.com/DQmcQBGWRNPRjqAHY5HnW9u2DkCJTELzF17YTjvHxTnKTLR/Tardigrade.png) ** Source** When the verdict was re-hydrated on its way back to Earth. scientists noticed that 68% of the body of the water bear survived the cold and space radiation.
