(<i>Original caption</i>): This is the first image from the OSIRIS-REx star tracker taken on Monday, Sept. 12. Similar to the way early sailors used the stars to navigate, the star tracker on OSIRIS-REx takes images of the stars and compares them to an on-board catalogue, which then tells the spacecraft navigation systems its attitude, or which way it is pointing.
