In the 1960s, the "Original 7" astronauts were both rock stars and daredevils. With movie star looks and a penchant for sports cars, Gordon Cooper was the youngest and the flashiest of the bunch. As a space pioneer, he first took orbit in Mercury-Atlas 9, setting a record that still holds today for the longest solo space flight in US history. During one of his key missions, while Cooper claimed to be scouring the globe for nuclear sites, he actually discovered something else: shipwrecks. Working for decades in secret, using the information he collected while orbiting the Earth, Cooper created a document that he thought could lead to unimaginable wealth – a treasure map from space. Uncover the truth – and the treasure – when Cooper's Treasure premieres on the Discovery Channel. Before passing away, Cooper shared his secret with long-time friend Darrell Miklos with the hope that his exploration would continue and the treasure would ultimately be found. Miklos is now setting out on a personal quest to fulfill the legacy of his lost mentor, once and for all realizing Cooper's long-held dream and proving to the world that the mysterious documents hold the key for a new generation of explorers.
