Space Missions and Their Objectives

The video highlights significant missions exploring small bodies in the solar system, such as comets and asteroids, to uncover insights about the solar system's origin and evolution. Key missions include ESA's Rosetta to comet 67P, JAXA's Hayabusa2 to asteroid 1999 JU3, NASA's Dawn to Vesta and Ceres, New Horizons to Pluto, and OSIRIS-REx to Bennu. These missions aim to gather data on composition, history, and potential water sources, contributing to our understanding of the solar system's past, present, and future.
