NASA scientists have found water, particles in Asteroid Bennu.

NASA’s OSIRIS-Rex mission found plumes erupting from the cosmic body’s surface — among a numerous other findings including evidence of water-bearing minerals. NASA spacecraft which will be returning to earth would be bringing a sample of asteroid in 2023. Bennu also revealed itself to be more rugged than expected, challenging the mission team to alter its flight and sample collection plans, due to the rough terrain. Bennu is the target of NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (Osiris-REx) mission, which began orbiting the asteroid on December 31 last year. Bennu, which is only slightly wider than the height of the Empire State Building, may contain unaltered material from the very beginning of our solar system. Speaking on the development ante Lauretta, Osiris-REx principal investigator at the University of Arizona said, ‘ The discovery of plumes is one of the biggest surprises of my scientific career. And the rugged terrain went against all of our predictions. Bennu is already surprising us, and our exciting journey there has just getting started.
