Watch Fmovies. To help visualize the dramatic final chapter in Cassini's remarkable story, NASA's Jet Propulsion Laboratory produced this short film that features beautiful computer-generated animation, thoughtful narration and a rousing score. Producers at JPL worked with filmmaker Erik Wernquist, known for his 2014 short film "Wanderers," to create a stirring finale video befitting one of NASA's most successful missions of exploration.
