OSIRIS-REx Asteroid Sample Return Mission Background

In an effort to better understand Near-Earth Objects, NASA is sending the OSIRIS-REx spacecraft to asteroid 1999 RQ36, a remnant of the early solar system.
OSIRIS-REx will study the asteroid’s composition and the evolution of its orbit, and it will return a pristine sample of the asteroid to Earth for further study. Includes interview with Dr. Joseph Nuth, NASA Deputy Project Scientist, OSIRIS-REx Mission. For more info: http://osiris-rex.lpl.arizona.edu/.
