En route‚ an onboard explosion deprives their spacecraft of most of its oxygen supply and electric power‚ forcing NASA’s flight controllers to abort the Moon landing‚ and turning the mission into a struggle to get the three men home safely.

As a young child I almost never heard my mother raise her voice to my father. They have been married for over twenty years now and I would consider all of them to be happy. She had gone to college to become a journalist and that’s where she met my father. The two fell in love and got married before graduation.
