Space probes are unmanned spacecraft designed to explore outer space and gather scientific data. They travel beyond Earth's atmosphere to study planets, moons, asteroids, and comets. Equipped with various instruments, space probes can capture images, analyze surface compositions, and measure environmental conditions. Some well-known space probes include Voyager 1 and Voyager 2, which have traveled beyond our solar system, and Mars rovers like Curiosity and Perseverance, which explore the surface of Mars. These missions help scientists learn more about the universe and the potential for life beyond Earth.
