An Aerojet Rocketdyne-built propulsion system helped to launch a Orbital ATK-made Cygnus space vehicle onboard a United Launch Alliance-made Atlas V rocket to transport cargo to the International Space Station.
The OA-6 flight“™s launch from Cape Canaveral Air Force Station in Florida Tuesday represents Orbital ATK“™s fifth cargo delivery mission to the ISS under the company’s Commercial Resupply Services contract with NASA, Aerojet Rocketdyne said Wednesday.
Aerojet Rocketdyne’s propulsion system consists of a company-built RL10C-1 upper-stage engine, 32 MR-106M monopropellant hydrazine thrusters, six helium pressurization tanks and 12 Centaur upper-stage thrusters.
Aerojet Rocketdyne“™s Arde subsidiary also supplied the pressure vessels used on the spacecraft and the rocket“™s first and second stages.
The propulsion system“™s MR-106M thrusters will work to help space vehicle perform in-orbit navigation in order for it to attach to the space station.
