Delta IV launched the third and fourth satellites of the Geosynchronous Space Situational Awareness Program (GSSAP), joining the first two, which flew in July 2014. The satellites operate near the geosynchronous belt to track and characterize objects there, and can maneuver close to them for a closer look.
