Documentary filmmaker Ryan White charts the remarkable journey of Opportunity, an exploration rover sent to Mars on an investigative scientific mission in 2003. Oppy, as she was christened by the research team responsible for her creation, was initially predicted to survive on the planet for ninety days. The aim was to gather data to feed back to NASA, and it continued to explore the red planet far beyond its expiration date, lasting nearly fifteen years on the planet's surface. The narrative interrogates the significance of Oppy's endurance for the future of interstellar discovery.
