NASA shows off its first asteroid samples delivered by a spacecraft

NASA on Wednesday showed off its first asteroid samples delivered last month by a spacecraft — a jumble of black dust and rubble that's the most ever returned to Earth. Scientists anticipated getting a cupful but are still unsure how much was grabbed from the carbon-rich asteroid named Bennu, almost 60 million miles (97 million kilometers) away. “It's been going slow and meticulous, but the science is already starting,” said the mission's lead scientist, Dante Lauretta of the University of Arizona.
