People have always been interested in space. Scientists study space to learn more about the universe. One important organization that studies space is National Aeronautics and Space Administration (NASA).
Rockets are used to travel into space. A rocket needs a lot of fuel to fly. When the fuel burns, it produces strong power that pushes the rocket into the sky. Rockets can carry astronauts, satellites, and scientific equipment.
Astronauts are people who travel and work in space. They wear special space suits because space has no air. The space suit helps protect their body and provides oxygen. In space, people cannot breathe normally like they do on Earth.
Satellites are also very important. They move around the Earth and send information. Satellites help with weather forecasting, communication, and navigation. Without satellites, it would be harder to use GPS or watch weather reports.
Space science helps humans understand the universe and improve technology on Earth. Scientists continue to explore space to find new knowledge.
