Lost in Space/Early Science Fiction

Lost in Space was a sci-fi television series (1965 – 1968) that spun-off of the adventures of the Space Family Robinson, a comic book published by Gold Key Comics in 1962. Husband and wife scientist team, John and Maureen Robinson, were selected from millions of families and tasked with traveling into the future in a spaceship, the Jupiter 2, to seek out another planet to colonize because Earth was becoming dangerously overpopulated. Also, along for the mission, were their daughters, Judy and Penny, son, Will, U.S. Space Corps pilot, Major Don West, Dr. Zachary Smith and a clunky (state of the art) robot. 

CBS aired the Lost in Space series, which they, ironically, chose to produce, over Star Trek. The destiny of the Robinson family was never known to viewers because the series was unexpectedly cancelled prior to the fourth season.
