Artificial asteroid retrieval may provide scientists and engineers with information regarding asteroid composition, as asteroids are known to sometimes contain rare metals such as palladium and platinum. Attempts at asteroid retrieval include NASA’s Asteroid Redirect Missions from 2013. These efforts were canceled in 2017.[2] But other asteroid-related missions remain functioning such as NASA’s OSIRIS-REx, which collected a sample of a near-Earth asteroid on October 22, 2020.[3]
