A United Launch Alliance (ULA) Atlas V 401 rocket launched the third Space Based Infrared System (SBIRS) Geosynchronous (GEO-3) satellite for the U.S. Air Force on 20 January 2017 at 7:42 p.m. from Space Launch Complex-41 at Cape Canaveral Air Force Station. The image is an ultra-wide time exposure of the boat-filled channel at Sebastian Inlet State Park where a lot of fishing was taking place on a calm night as the Atlas V streaks into space.
The ULA press release about the launch describes the mission:
The Space Based Infrared System is considered one of the nation’s highest priority space programs and is designed to provide global, persistent, infrared surveillance capabilities to meet 21st century demands in four national security mission areas:
Reliable, unambiguous, timely and accurate warning for theater and strategic missile launches.
Delivery of critical information supporting the effective operation of missile defense systems.
Ability to characterize infrared (IR) event signatures, phenomenology and threat performance data.
Delivery of comprehensive IR data to help characterize battlespace conditions.
The SBIRS team is led by the Remote Sensing Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Lockheed Martin is the prime contractor, with Northrop Grumman as the payload integrator. Air Force Space Command operates the SBIRS system.
