I've been wondering about this for a while. The team modified the heli's software to gather data, which it could in theory collect for many years... AFAIK We've not received any images from the rover since 1069, is it still trying to contact the rover daily? Or has that function been turned off to preserve power, so it can gather data for more years? I hope you're right as I hoped to see periodic images as the rover traversed towards the crater rim :)
