Just the other day I heard about the heroic effort[0] to restore communication with Voyager 2 after they inadvertently changed the antenna to point in the wrong direction due to some planned manoeuvres.
Definitely worth a listen if you get the time.
For me personally, I feel this project is the greatest engineering effort in human history bringing together the work of Newton, Kepler, the mathematics of the celestial navigation, gravitational assist techniques[1], etc. necessary to keep a little probe on its route accurately over 50 years in space.
