Space probes are unmanned spacecraft designed to explore outer space and gather data about celestial bodies. They travel beyond Earth's atmosphere to study planets, moons, asteroids, and comets. Equipped with scientific instruments, space probes can capture images, analyze surface compositions, and measure environmental conditions. These probes can be sent on missions to specific targets, such as Mars or Jupiter, and often communicate their findings back to Earth. Notable examples include the Voyager probes, which have traveled beyond our solar system, and the New Horizons probe, which provided detailed images of Pluto.
