ULA Marks 85th Successful Launch by Delivering 3 Satellites into Orbit for USAF
A United Launch Alliance (ULA) Delta IV rocket successfullylaunched the AFSPC-4 mission for the U.S. Air Force on July 28 at 7:28 p.m. EDT from Space Launch Complex-37. This is ULA's eighth launch in 2014, and the 85 th successful launch since the company was formed in December 2006 .
"The ULA team is proud to have delivered the twin Geosynchronous Space Situational Awareness Program (GSSAP) spacecraft to orbit today," said Jim Sponnick , ULA vice president, Atlas and Delta Programs. "We are privileged to work with a top notch U.S. government and contractor mission team that is committed to mission success."

This mission was launched aboard a Delta IV Medium-plus (4,2) configuration Evolved Expendable Launch Vehicle (EELV) using a single ULA common booster core powered by an Aerojet Rocketdyne RS-68 main engine, along with two ATK GEM-60 solid rocket motors. The upper stage was powered by an Aerojet Rocketdyne RL10B-2 engine, with the satellite encapsulated in a 4-meter-diameter composite payload fairing.
In addition to the two GSSAP satellites delivered to near-geosynchronous orbit, the secondary payload, Automated Navigation and Guidance Experiment for Local Space (ANGELS) satellite is managed by the Air Force Research Laboratory (AFRL).
The twin GSSAP spacecraft will support U.S. Strategic Command space surveillance operations as a dedicated Space Surveillance Network sensor. The GSSAP will also support Joint Functional Component Command for Space to collect space situational awareness data, allowing for more accurate tracking and characterization of man-made orbiting objects. ANGELS examines techniques for providing a clearer picture of the environment surrounding our nation's vital space assets.
ULA's next launch is the Atlas V GPS IIF-7 mission for the Air Force scheduled for Aug. 1 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida .
The EELV program was established by the United States Air Force to provide assured access to space for Department of Defense and other government payloads. The commercially developed EELV program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems.
With more than a century of combined heritage, United Launch Alliance is the nation's most experienced and reliable launch service provider. ULA has successfully delivered more than 80 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.
