From this answer to my previous DSCOVR question, and this and this and this article, it seems that DSCOVR used one or more of its ten thrusters for the long burns for mid course correction (MCC) and Lissajous orbit insertion (LOI). These were to be 50 minutes and 5.3 hours, respectively.
How did the spacecraft maintain the proper thrust direction? If it were a single engine located on a central axis, it might have been slightly gimbaled. But for these 5N thrusters, were they distributed around an axis and used in groups of 3 or more? During a long burn, it's important to maintain the thrust vector in the correct direction. Were they pulsed in order to maintain the proper direction, or other thrusters on the sides used, or attitude adjusted with reaction wheels (gimbaling the entire spacecraft)?
I would also like to see a drawing of some kind indicating the locations of the ten thrusters and the directions they point, so I can visualize this better.
note: "They could have..." type answers are sometimes helpful, but here I'd like something definitive.
