Orbital ATK will launch a Minotaur IV rocket carrying the ORS-5 satellite for the United States Air Force (USAF) on Friday, August 25 from Cape Canaveral Air Force Station in Florida.
The launch window will be open from 11:15 p.m. EDT August 25 to 3:15 a.m. EDT August 26.
The launch is part of the Orbital/Suborbital Program-3 (OSP-3) contract and the fifth mission of the ORS (Operationally Responsive Space) program.
ORS-5, also known as SensorSat, is designed to scan for other satellites and debris to aid the U.S. military’s tracking of objects in geosynchronous orbit and act as a gap filler for the SBSS Block 10 satellite.
The satellite, which weighs 140 kg, is planned to operate from a low inclination orbit of 500-700 km height to observe satellites in the geostationary belt.
For the ORS-5 launch, the Minotaur IV will use two Orion 38 upper stage motors. The final Orion 38 motor burn will reduce the angle of the ORS-5 satellite’s orbit, redirecting the spacecraft to equatorial orbit.
