NASA spacecraft sent asteroid rubble flying in sample grab

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. “We really did kind of make a mess on the surface of this asteroid, but it’s a good mess, the kind of mess we were hoping for,” said lead scientist Dante Lauretta of the University of Arizona at Tucson.
