OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is the National Aeronautical and Space Administration's first asteroid sample return mission. OSIRIS-REx seeks answers to the questions that are central to the human experience: Where did we come from? What is our destiny? Asteroids, the leftover debris from the solar system formation process, can answer these questions and teach us about the history of the sun and planets. NASA's Goddard Space Flight Center in Greenbelt, MD, provides overall mission management, systems engineering and safety and mission assurance for OSIRIS-REx. Lockheed Martin Space Systems in Denver is building the spacecraft. OSIRIS-REx is the third mission in NASA's New Frontiers Program.

The collection contains records of the OSIRIS-REx next hit Asteroid Sample Return Mission, a NASA mission led by Primary Investigator Dante Lauretta of the University of Arizona Lunar and Planetary Laboratory in collaboration with Goddard Space Flight Center and Lockheed Martin. The records consist of supplemental documents, project management reports, images and other items to better contextualize and support mission publications and data that are being deposited to the planetary data system. Also included in the collection are mission notes and summaries from the OSIRIS-REx next hit Mission Information Wiki page. This is a born-digital collection with online access through the University of Arizona Libraries Campus Repository and is currently ongoing.
