Space exploration is the endeavor of humans to use technology to reach, explore, and exploit the
space outside the
Earth's atmosphere. It is generally based on the use of
rockets to transport machines, animals, and humans to space. Objects launched into space may stay in
orbit around Earth, travel in the space between the
planets, or aim to leave the space dominated by the
Sun completely.
