Planetary missions involve sending spacecraft, probes, or rovers to explore and study other planets, moons, asteroids, or comets within our solar system. These missions typically involve conducting scientific experiments, taking measurements, capturing images, and collecting samples to better understand the geological, atmospheric, and potentially biological processes occurring on these celestial bodies. Planetary missions have provided valuable insights into the origins and evolution of our solar system, as well as the potential for life beyond Earth. Some notable examples of planetary missions include the Mars rovers Spirit, Opportunity, and Curiosity, the Cassini mission to Saturn, and the New Horizons mission to Pluto.
