No one knows why rocks are exploding from asteroid Bennu

From Ars Technica:
"For the last year, NASA’s OSIRIS-REx spacecraft has been circling a large asteroid named Bennu that regularly passes uncomfortably close to Earth. The spacecraft has been painstakingly mapping the asteroid’s rocky surface using a suite of cameras and other instruments that will help it determine where to land next year. ... NASA has already started making surprising discoveries around this alien world. Earlier this year, the OSIRIS-REx team witnessed particles exploding from the asteroid’s surface—and it’s not sure why."
