OSIRIS-APEX is a NASA mission designed to reuse the OSIRIS-REx spacecraft for further exploration after it completed its primary mission of returning samples from the asteroid Bennu. The new mission, which stands for “OSIRIS-REx Asteroid Post-Encounter eXtension,” aims to rendezvous with a different asteroid, named Apophis. Scheduled to encounter Apophis in 2029, OSIRIS-APEX will study the asteroid’s surface and composition, providing valuable data that can enhance our understanding of asteroids and their potential threat to Earth.
