Satellites are devices that use sensors to observe Earth and our solar system.
Satellites can observe the Earth's atmosphere, surface and oceans.
A rocket launches the satellite into space then detaches itself from the satellite. The satellite uses on-board boosters to position the satellite in the proper orbit and at the proper viewing angle. This scienticfic phenomena is based on orbital mechanics. Newton's laws of Motion tells use that an objeect in motion will stay in motion. When a satellite is launched it would continue in a straight line. except that an outside force is action upon it.
