I am reading this article about DSCOVR which links (ref 16) to this: DSCOVR: Mission Success for Moog Engines Over a Decade Later , about the recertification by MOOG of the MONARC 5N monopropellant engines and thruster valves.
When I read these two, I don't understand - are there both engines and thrusters? Could someone explain the distinction - and possibly locate a clear diagram with DSCOVRs various propulsion elements used for the mid-course correction (MCC), Lissajous orbit insertion (LOI), and all station-keeping tasks? Here is a sample paragraph from here:
"The 5N engines will be used for attitude control and minor adjustments to maintain the satellite’s Lagrange-1 (L-1) orbit one million miles from Earth; DSCOVR is the nation’s first operational spacecraft in deep space. DSCOVR has two key burns: Mid-Course Correction (MCC) and Lissajous Orbit Insertion (LOI). The thrusters will be used to perform the MCC for 50 minutes and LOI for 5.3 hours. After reaching L-1, DSCOVR will perform station-keeping and momentum unloading with the thrusters."
