his apparent 'cowardice' has condemned them to starvation. The two ships, with Carter piloting Reconnaissance Eagle Two, set off for Arkadia. During the flight, Helena attempts to make Ferro and Anna see reason. The fugitives, in turn, try to convince the doctor that they are neither mad nor brainwashed puppets. Profoundly affected by their experience on the planet, they are willing servants of a higher destiny. The return of life to Arkadia gives purpose to the Moon's odyssey...and if Alpha's role is that of sacrificial lamb, so be it. After establishing orbit around Arkadia, the two ships dock and the exchange is made. As Ferro descends to the surface, Carter sets course for home. Once in radio range of Alpha, the astronaut reports that Helena is aboard and safe. With that fact certain, Koenig redeems himself. He reveals his secret order to place a homing transmitter on Ferro's Eagle. In addition, Eagles Three and Five are standing by to lift off; their mission is to locate the fugitive ship and retrieve the supplies. As Ferro touches down on Arkadia, the Moon unexpectedly lurches into motion. Not coincidentally, the power loss begins to lessen. Koenig cancels the pursuit mission; with full power returning, the lost supplies are irrelevant. He immediately calls Carter, ordering him to hit the throttle so as not to be left behind. On Arkadia, as Ferro and Anna unload the Eagle, they are shocked to see the Moon in motion. The couple holds each other, watching the Moon dwindle in size. Though completely alone on a barren world, they are comforted by the knowledge of having come home. After Helena's safe return to Alpha, she and Koenig speculate on the role of the mysterious unknown force of Arkadia and its influence on Ferro and Anna. The viewer returns to the present as Koenig concludes that, with Earth settlers returning life to Arkadia, events have come full circle. While destiny may have been fulfilled with Luke Ferro and Anna Davis becoming a 21st-century Adam and Eve, he writes, the Alphans must keep faith that the Moon's ongoing journey has a greater purpose...
