Interplanetary probes are robotic spacecraft designed to explore planets and other celestial bodies within our solar system. They gather data about the atmosphere, surface, and composition of these bodies, helping scientists understand their characteristics and history. Notable examples include the Voyager probes, which have traveled beyond the outer planets, and the Mars rovers, which study the Martian surface. These probes are equipped with various instruments, such as cameras, spectrometers, and magnetometers, to collect scientific information. They transmit their findings back to Earth for analysis, contributing to our knowledge of planetary systems and the potential for life beyond our planet.
