Wasn’t the expected life only a few weeks/months?
Yeah - they sure got a lot of great “extra” science out of the thing. Opportunity was pretty much dormant anyway. I think it wasn’t too long ago that they woke it up to test the systems, but then shut it down again.
I’m assuming that the still active rover - Curiosity, is still okay?
Opportunity’s initial mission length was 90 Martian days, obviously hoping for more and got that in spades. In early June this year it went into hibernation due to the dust storms, and at this point, may not be coming back out.
Curiosity has been on Mars 6 years now and is still operating.

Its power source is a radioisotope thermoelectric generator. Other than a drilling arm problem which Nasa found a work around for, it is still functioning during the dust storm.
