Last major update was back in the ninety's. Good thinking there, as that code wrote a bunch of timed routines that would cycle endlessly on a fixed schedule so the craft could continue to collect and transmit data, even if we lost control. Last I heard, we can still send minor routine tweaks if needed, but they take forever to load and test before going live. Long as we can still get telemetry, we know they're still doing their job. Problem being, there's only one antenna still in service (Canberra) that can still talk to them, and that's going sporadic.
