Rod Rocket is the first animated cartoon with production credited to Filmation, debuting in syndication in 1963. The show was produced in five-minute cliffhanger segments, with five segments making a full story. Television stations could broadcast the single-segment version daily on their local children's afternoon show, or package them together to make 26 weekly half-hour shows.
A boy named Rod Rocket and his best friend, Joey, are sent by wise codger Professor Argus on an exploratory mission in a spaceship called the Little Argo. He waits for them at home with his teenage granddaughter, Cassie. While in space, Rod and Joey constantly battle two bumbling cosmonauts.
