Planetary missions are scientific explorations conducted by spacecraft to study planets, moons, and other celestial bodies in our solar system. These missions aim to gather data about the composition, atmosphere, and geology of these bodies, helping scientists understand their formation and evolution. Notable examples include the Mars Rover missions, which explore the surface of Mars, and the Voyager spacecraft, which have traveled beyond the outer planets. These missions can be flybys, orbiters, or landers, each designed for specific objectives. For instance, Juno is an orbiter studying Jupiter's atmosphere and magnetic field, while the New Horizons mission provided the first close-up images of Pluto. Each mission contributes valuable knowledge about our solar system and the potential for life beyond Earth.
