Apollo 13: 4. Power brokers

Apollo astronauts freeze in darkness, struggling to save power. If the battery dies, so do the space crew. And as the damaged spacecraft loses its navigation systems, they must rely on the Sun for guidance. The astronauts' plight becomes a national crisis. Millions across the world tune in to the television coverage. Meanwhile, Nasa mission control faces a race against time to devise a plan, launching one of the greatest rescue missions in the history of space exploration.
