OSIRIS-REx brings together all of the pieces essential for a successful asteroid sample return mission, - The University of Arizona’s (Tucson, AZ) leadership in planetary science and experience operating the Mars Phoenix Lander Lockheed Martin’s (Denver, CO) unique experience in sample-return mission development and operations NASA/GSFC's (Greenbelt, MD) expertise in project management, systems engineering, safety and mission assurance, and visible-near infrared spectroscopy KinetX’s (Tempe, AZ) experience with spacecraft navigation and Arizona State University’s (Tempe, AZ) knowledge of thermal emission spectrometers. Only by understanding the organic chemistry and geochemistry of an asteroid sample can this knowledge be acquired. Knowledge of its nature is fundamental to understanding planet formation and the origin of life. This asteroid is both the most accessible carbonaceous asteroid and the most potentially hazardous asteroid known. After several months of proximity operations to characterize the asteroid, OSIRIS-REx flies a TAG (Touch-And-Go) trajectory to the asteroid’s surface to collect at least 60 gram of pristine regolith sample for Earth return. The rendezvous with Bennu is planned for October 2018. The objective is to rendezvous and thoroughly characterize near-Earth asteroid Bennu (previously known as 1019551999 RQ36).
