A Gold Star for the Star Tracker!
2016-09-12 - This is the very first image taken by the OSIRIS-REx star tracker on Monday, September 12, 2016. Similar to the way early sailors used the stars to navigate prior to the invention of special instruments, OSIRIS-REx’s star tracker captures images of the stars, comparing them to an on-board catalogue and reporting its attitude (the direction in which it is pointing) to the spacecraft navigation systems.
