Samples arrive in Utah desert

A capsule containing roughly 120 grams of rock touched down in Utah on September 23, 2023. Researchers worldwide received small portions of this cargo for detailed chemical analysis shortly after the landing.

Jupiter role in asteroid birth

New data indicates Bennu formed where inner and outer solar system materials mixed together. Professor Maria Schönbächler from ETH Zurich notes that Jupiter played a surprising part in this process.

Ancient history rewritten by study

These findings challenge previous theories about the location where Bennu originated billions of years ago. The asteroid completes an orbit around the Sun every 1.2 years and visits Earth roughly every six years.
