SIU Geologist observes NASA's OSRIS-Rex Launch
October 25, 2016
The OSIRIS-REx mission is a NASA New Frontiers-class mission to visit the asteroid 101955 Bennu and return a sample of the surface. The spacecraft will reach Bennu in 2018, begin a detailed orbital campaign, and then collect a sample of the surface for return to Earth in 2023. Bennu was chosen for study and sample return because it is a primitive asteroid that has a small chance of hitting the Earth between 2169 and 2199. Bennu is a primitive asteroid that should have water-bearing minerals on the surface. Importantly, these water-bearing minerals will give clues about the origin of water on Earth and possibly even the origin of life on Earth.
