Planetary exploration refers to the scientific study of planets, moons, and other celestial bodies in our solar system and beyond. This exploration is conducted using spacecraft, telescopes, and robotic landers, which gather data about the composition, atmosphere, and geology of these bodies. Notable missions include those to Mars, Jupiter, and Saturn, which have provided valuable insights into their environments. The primary goals of planetary exploration are to understand the formation and evolution of planets, search for signs of past or present life, and assess the potential for future human colonization. Missions like NASA's Perseverance Rover and the European Space Agency's Rosetta have significantly advanced our knowledge of the solar system.
