Asteroid samples from NASA's epic OSIRIS-REx mission show Bennu was born from fire and ice
Samples from NASA's OSIRIS-REx mission to asteroid Bennu suggest it was formed from a mix of hot and cold materials in the planet-forming disk 4.5 billion years ago. Analysis of the samples' isotopic composition indicates Bennu likely originated near the water-ice line in the early solar system, shaped by Jupiter's influence. This challenges previous assumptions about Bennu's origins in the outer solar system.

NASA's OSIRIS-REx asteroid samples reveal Bennu's fire-and-ice origin
Samples from NASA's OSIRIS-REx mission to asteroid Bennu suggest it was formed from a mix of hot and cold materials in the planet-forming disk 4.5 billion years ago. Analysis of the samples' isotopic composition indicates Bennu likely originated near the water-ice line in the early solar system, shaped by Jupiter's influence. This challenges previous assumptions about Bennu's origins in the outer solar system.
Why it matters
The OSIRIS-REx mission returned samples from asteroid Bennu to Earth on September 24, 2023. Understanding Bennu's origins helps scientists learn about the early solar system and planetary formation. The samples provide valuable insights into the conditions and processes that shaped the solar system's rocky planets.
