NASA's plan to scoop up dirt and gravel from an asteroid has hit a snag, but scientists say they can overcome it. In a paper released Tuesday by the journal Nature, scientists say they plan to take a closer look at a few smaller areas that might work. A Japanese spacecraft, Hayabusa2, touched down on another asteroid in February, also on a mission to collect material. Japan managed to return some tiny particles in 2010 from its first asteroid mission. ———The Associated Press Health & Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education.
