- Earn Your Happy Ending: The NASA astronaut Colonel Theodore Harris saw a strange violet light while onboard the Aspire 7 on September 16, 1963. The light enveloped the capsule and he aborted the mission. His steadfast claim that he had encountered aliens while in space was not taken seriously and the NASA psychological assessment determined that it had merely been a hallucination. Harris was completely discredited. The continual accusations that he was mentally unstable led him to check himself into a psychiatric institution for a brief period. On one occasion, he even hacked into a computer at The Pentagon in order to access his file but the charges were dropped. Harris is furious when he learns that his old friend and fellow astronaut Wayne caught a glimpse of similar lights during an orbit of Earth but kept it to himself for the sake of his career. In the words of his wife Madelaine, he was a "one man trainwreck." Although she left him because she could no longer handle the stress, they never stopped loving each other. On a second trip to space aboard the Daedalus XL-141 in 2001, Harris once again encountered the aliens. As their intention had been to observe but not interfere, they send him back in time to 1963 and alter history so that his mission was successful. He has the opportunity to live his life over again and avoid making the same mistakes.
