Story summary

NASA's OSIRIS-REx mission found asteroid Bennu contains diverse materials, including stardust and organic compounds.
Studies indicate Bennu formed from a larger parent asteroid that fragmented in the asteroid belt.
Samples reveal chemical changes due to water interactions and space weathering, shedding light on early solar system processes.
Bennu's preserved materials enhance understanding of planetary formation and the origins of water and organic matter on Earth.

History

Historical Context

NASA's Apollo 11 mission achieved a historic milestone in 1969 by landing humans on the Moon, returning 47.5 pounds of lunar material that enhanced our understanding of celestial bodies. Similarly, the OSIRIS-REx mission, which collected samples from asteroid Bennu in 2020, returned to Earth on September 24, 2023, revealing organic compounds that may shed light on the origins of water and life on Earth.
