The Science of OSIRIS-REx

On Sept. 6, NASA previewed the science of the Origins Spectral Interpretation Resource Identification Security – Regolith Explorer, or OSIRIS-REx mission, during a pre-launch news conference at the agency’s Kennedy Space Center in Florida. OSIRIS-REx – the first U.S. mission to sample an asteroid is targeted to launch Sept. 8 at 7:05 p.m. ET to the near-Earth asteroid Bennu, to survey the surface, retrieve at least 60 grams (2.1 ounces) of surface material, and return it to Earth for study. Analysis of the sample will reveal the earliest stages of the solar system’s evolution and the history of Bennu over the past 4.5 billion years.
