The Ulysses spacecraft, which is still in orbit although decommissioned and not operational, remains one of the few spacecraft to leave the ecliptic plane of the solar system to a significant degree. It studied the poles of the Sun. It launched in 1990, and the total mission duration was over eighteen years.
We estimate these photos are from the early 1980s. They're of the flight hardware for the magnetometer, which now drifts quietly with the rest of the silent spacecraft, between Jupiter and the Sun.
