Tucked into a shipping container, NASA's OSIRIS-REx spacecraft is unloaded from an Air Force C-17 cargo aircraft on the Shuttle Landing Facility runway at Kennedy Space Center in Florida. The spacecraft traveled from Lockheed Martin's facility near Denver, Colorado to Kennedy to begin processing for its upcoming launch, targeted for Sept. 8 aboard a United Launch Alliance Atlas V rocket. #OSIRIS-REx will be the first U.S. mission to sample an #asteroid, retrieve at least two ounces of surface material and return it to Earth for study. This asteroid, Bennu, may hold clues to the origin of the solar system and the source of water and organic molecules found on Earth.
