Did you know that astronauts swim in the air and hang upside down? This is because there is no gravity in space. Our solar system has moon, asteroids, comets, the sun, and planets. Earth is the third planet from the sun. It takes one year for the earth revolves around the sun. Would you explore with me our astronauts travel in space? Astronauts are people who travel in space. Astronauts are scientists who are interested in the solar system. Scientists wanted to discover other works. At first, they started using telescopes which made the planets seem closer. Soon the astronauts weren’t satisfied about seeing the planet from so far away. So they started dreaming about going to space. Now, if astronauts are sent into space, what do they do? Astronauts are sent into space to launch satellites. Their report includes more than one hundred experiments treating people who can’t see. They study what astronauts eat, nutritious foods, and vitamins. Astronauts also collected rock samples from the moon that they have helped scientists understand how the moon may have formed.
