A lone spacecraft is hovering 12 miles above the surface of a tiny asteroid millions of miles away, closely examining its surface. And it just sent back its first readings.

As part of NASA's Origins Program, the OSIRIS-REx spacecraft traveled to an asteroid called Bennu some 100 million miles (160 million kilometers) from the Sun, finally arriving at the 1,600-foot-wide (487-meter) asteroid on December 3.
