What if opposing forces in the next world war employed noxious, new weapons that had never been used before. What if much of Earth became uninhabitable? Could a heroic team of five astronauts armed with 3-D printers, infrared-resistant plants and oxygen-producing bacteria save mankind by terraforming Mars? Readers are invited to travel with the crew of Courage One on its mission to Mars. Join Commander Michael Ryan and his fellow astronauts as they explore and make extraordinary discoveries, with the assistance of Dixie GPS, the robot dog. This is a work of science fiction, which the author predicts will become a reality within the next hundred years. He believes that American astronauts will be the first to step foot on Mars and explore all the resources that Mars has to offer. Terraforming Mars to make it habitable is in our future.
