The Juno spacecraft includes 12 Aerojet Rocketdyne MR-111C 1.0 lbf monopropellant
hydrazine Rocket Engine Assemblies that have provided attitude control for the spacecraft throughout its journey, as well as during insertion into Jupiter's orbit, which occurred on July 4, 2016.

," Aerospace Science and Technology, vol.
This recent technological achievement involved running the patented Cyclone Engine by the combustion of an environmentally friendly monopropellant
called Moden Fuel.
The major objective of the contract is to design a monopropellant
propulsion system, which is a mission critical subsystem of the satellite Guidance and Navigation Control System.
"A year ago it was a hybrid rocket, but now for the first record attempt we will use only the monopropellant
part of the rocket.
Once separated from the launch vehicle, the GPM satellite uses 12 Aerojet Rocketdyne MR-106L 5.0 lbf monopropellant
thrusters for attitude control.
Early in 2009 the project decided that the early runs of the car would be conducted with a monopropellant
Twelve Aerojet Rocketdyne monopropellant
(hydrazine) thrusters in four modules on the Delta IV upper stage provided roll, pitch and yaw control as well as settling burns for the upper stage main engine.
Running excess HTP through the system has been successfully used to extinguish the flame in earlier tests of the monopropellant
rocket, too, and was the plan for the Newquay firing.
Aerojet Rocketdyne's role in the launch primarily began with the second stage, when a single RL10A-4-2 engine ignited to place the TDRS-L into orbit, helped by the 12 Aerojet Rocketdyne monopropellant
(hydrazine) thrusters in four modules on the Atlas V Centaur upper stage providing roll, pitch and yaw control as well as propellant settling burns during ascent.
