The film follows Opportunity, the Mars Exploration Rover affectionately dubbed Oppy by her creators and scientists at NASA. Oppy was originally expected to live for only 90 days, but she ultimately explored Mars for nearly 15 years.

“For large segments of its running time, “Good Night Oppy” is more than just a documentary; it’s an animated film as well — and a hugely entertaining one at that.”
