Watch: NASA spacecraft sent asteroid rubble flying

NASA's Osiris-Rex spacecraft crushed rocks and sent rubble flying as it briefly touched an asteroid, a strong indication that samples were collected for return to Earth, officials said Wednesday. Scientists won't know until next week how much was gathered at Asteroid Bennu, they want at least a handful of the cosmic rubble. But close-up pictures and video of Tuesday's touch-and-go operation raised hopes that goal was achieved.
