I would bet they have one or more simulators (“digital twin” in the parlance of our times). I’d want one simulator to always reflect the current state of the probe (with state data assimilated periodically from the real probe). Then other simulators can be used to test management changes to see how the system might respond.

Sadly they do not, but they are starting to write one.
