OSIRIS-REx spacecraft completes assembly stage, begins environmental testing

University of Arizona

OSIRIS-REx, led by the University of Arizona, will be the first U.S. mission to return samples from an asteroid to Earth for further study. The simulation concludes with a test in which the spacecraft and its instruments are placed in a vacuum chamber and cycled through the extreme hot and cold temperatures it will face during its journey to Bennu. OSIRIS-REx is scheduled to ship from Lockheed Martin’s facility to NASA’s Kennedy Space Center next May, where it will undergo final preparations for launch. ### NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering and safety and mission assurance for OSIRIS-REx. Dante Lauretta is the mission’s principal investigator at the University of Arizona.
