NASA's 1st asteroid-bound spacecraft sends 1st image of rock
After an almost two-year journey, NASA spacecraft OSIRIS-REx, caught its first glimpse of asteroid Bennu last week and began its final approach toward the space rock. The spacecraft obtained the image from 2.2 million km and is scheduled to arrive at Bennu in December. OSIRIS-REx is NASA's first mission aimed to visit a near-Earth asteroid and send back its sample.
