The Day Job for Juno's SRU (Artist's Concept)

This animation illustrates how the Stellar Reference Unit (SRU) star camera aboard NASA's Juno spacecraft supports "attitude determination" -- the knowledge of which way Juno is pointing as the spacecraft navigates through space. The SRU takes images of star fields and searches for bright stars with known positions to help Juno obtain its bearings. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA22961
