DULLES, Virginia, July 14, 2015 (Orbital ATK PR)– Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense technologies, received a $23.6M contract from the U.S. Air Force’s Operationally Responsive Space (ORS) Office to launch the ORS-5 SensorSat spacecraft in mid-2017, using a rocket from the company’s Minotaur Launch Vehicle Family.
The ORS-5 mission will employ an Orbital ATK Minotaur IV rocket lifting off from Launch Complex-46, operated by Space Florida at Cape Canaveral Air Force Station. This will be the first time a Minotaur vehicle will have flown from this range.
“Launching from the Cape adds another capability to our program and brings us to four ranges from which Minotaur can launch,” said Rich Straka, Vice President and General Manager of Orbital ATK’s Launch Vehicles Division. “This flexibility and multiple vehicle configurations enables Minotaur launch vehicles to be tailored to meet mission requirements while offering the lowest cost flight-proven launch vehicles available to the U.S. government.”
This Minotaur IV rocket uses retired Intercontinental Ballistic Missile (ICBM) Peacekeeper boosters for the first three stages and Orbital ATK Orion 38 solid rocket motors for the upper stages. Orbital ATK integrates the vehicle using flight-proven avionics, structures, software and other components that are common among Orbital ATK’s space launch vehicles.
Using a launch vehicle comprised of solid rocket motors requires minimal pad infrastructure, which helps lower mission costs. The team will integrate the final launch vehicle using the Orbital ATK team at the Cape with a team comprised of employees from both Orbital and ATK heritage companies.
“This is a prime example of where the synergies from the Orbital ATK merger are providing real benefits to our customers, by being able to deploy one launch team that possesses expertise from critical propulsion and avionics subsystems, to the full systems engineering understanding of the vehicle,” said Scott Lehr, President of Orbital ATK’s Flight Systems Group.
The award was won as a competitive commercial launch contract for the Operationally Responsive Space Office and will be licensed by the FAA.
The Minotaur family of vehicles has carried out 25 consecutive launches with a 100% mission success record and has placed a total of 74 satellites into orbit. Employing a combination of U.S. government-supplied rocket motors and Orbital ATK’s proven commercial launch technologies provides incredible cost-savings for government payloads, enables the U.S. to compete with other countries who use their retired assets for commercial launch and keeps a critical skilled workforce employed.

25 in a row. 100% success. Not surprising with a simple solid. I hope they can launch much heavier payloads from there using O-ATK solid segments and their other SRM. Nothing much to think about with solids. In the countdown check to exercise the steering. Check to see the payload is ok. Launch. I am really tired of saying that thing is blowing up. Orbital did lose a NASA sat. when the faring did not separate. Must be more than 25 launches ago or a different version. I would use solids for all launches if possible. I use to think that if ULA could do it than anyone else could.Not any more. I give up on liquids. Not logical to use them. I thought that if one made it then the ones after would too. I am the only one giving up though.
The OCO satellite was launched/lost on a Taurus-XL rocket.
Personal opinion: solids are for those not able to master liquids!
Yes they are simple, but they are also very inefficient and totally impractical for any serious exploration architecture. You can’t simply refuel them.
