Sol Tobias is an American astronaut in the National Aeronautics Spacy Agency. Nothing is known about his past, but the greatest accomplishment of his NASA career was going into orbit with Astronaut Ryan in the Scorpio 6 space capsule. They were going to complete a series of orbits at which end Tobias was going to enter the unmanned Scorpio EX-1 capsule as the two of them returned to Earth safely. During their orbits, Tobias received a message from Earth spelling out his name in support which he was unaware was a rescue attempt by the Castaways. Unfortunately, his mission when awry when the Scorpio EX-1 malfunctioned and descended to Earth without him, and his mission was scrubbed with both Tobias and Ryan returning to Earth together.
- Sol Tobias was played by actor Scott Graham.
