The Last Pioneer
As the Argo approaches one of Neptune's moons, which is similar to Earth, an attempt on Earth to use the sun's energy to cool it off fails. Meanwhile, Commander Wildstar heads a landing party to locate the source of several radio transmissions coming from the planet. Just then, the party encounters fire from a lone gunman, and they pursue the man, who appears to be from Earth. They find the man, his daughter, and her husband, the latter of whom is seriously ill and eventually dies. When the man collapses, the team transports him and his daughter back to the Argo. On the other side of the planet, Dagon prepares to attack the Star Force with an array of ships designed to reflect lasers fired from the planet's surface at their target. He activates the weapon, attacking the Argo from all sides. Wildstar heads off to locate the base and destroy it. 308 days remain before the sun destroys Earth..
