ORS-5 Satellite For The U.S. Air Force Boosted Into Orbit Saturday
An Orbital ATK Minotaur IV space launch vehicle successfully launched and placed into orbit the U.S. Air Force’s Operationally Responsive Space-5 (ORS-5) spacecraft on Saturday. The Minotaur IV launched from Cape Canaveral Air Force Station’s Space Launch Complex 46 (SLC-46), which is operated under license by Space Florida.
The rocket’s first stage ignited at 2:04 a.m. (EDT). Approximately 28 minutes later, the Minotaur IV deployed the ORS-5 satellite into its targeted low inclination orbit 372 miles above the earth. From this orbit, ORS-5 will deliver timely, reliable and accurate space situational awareness information to the United States Strategic Command through the Joint Space Operations Center.
“This was our first Minotaur launch from Cape Canaveral Air Force Station, demonstrating the rocket’s capability to launch from all four major U.S. spaceports,” said Rich Straka, Vice President and General Manager of Orbital ATK’s Launch Vehicles Division. “With a perfect track record of 26 successful launches, the Minotaur family has proven to be a valuable and reliable asset for the Department of Defense.”
The Minotaur family of launch vehicles is based on government-furnished Peacekeeper and Minuteman rocket motors that Orbital ATK has upgraded and integrated with modern avionics and other subsystems to produce an affordable launcher based on flight-proven hardware. Minotaur rockets have now launched from ranges in California, Virginia, Alaska and Florida. The vehicles are procured under the OSP-3 contract administered by Kirtland Air Force Base.
“Orbital ATK has launched nearly 100 space launch and strategic rockets for the U.S. Air Force,” said Scott Lehr, President of Orbital ATK’s Flight Systems Group. “We’re proud to be a partner they can count on.”
The ORS-5 launch was the sixth Minotaur IV flight. The Minotaur IV is capable of launching payloads up to 4,000 lbs. to low-Earth orbit. This mission’s Minotaur IV configuration included three decommissioned Peacekeeper stages, an Orion 38 solid-fuel upper stage and an additional Orion 38 insertion stage for the payload.
