This article about a space vehicle is interesting - https://en.wikipedia.org/wiki/Akatsuki_%28spacecraft%29
Akatsuki failed to be injected into a Venus orbit in 2010, so continued to orbit around the sun. It has recently been injected into Venus orbit years after originally planned, and perhaps towards the end of the planned vehicle lifetime. The vehicle has been subject to environments which were outside its specification range, but it seems that most of the functions may be operational, despite some deterioration due to age and environments.
