The first astronaut candidate task is undergoing a survival training course consisting of a six-day trek through the desert. Meanwhile, Mutta is still worried about Amanti's reaction after she read his fortune.

NASA and JAXA have decided to bring Hibito back to Houston, placing him in a supporting role. Hibito has no choice but to pack up and make his farewells.

Mutta and Kenji have overcome their initial shock after hearing that only one of them will be chosen to go to the moon. Now that they're working together again, everything seems to be going right with their construction of the Moonbase.

Hibito takes the test to determine if he will be allowed to return to active duty. While Chief Butler issues a green card for a false malfunction, to see how Hibito reacts under pressure, another malfunction also occurs that Butler doesn't expect.

Mutta has returned from his training in the desert and gets some rest as Christmas approaches. Meanwhile, Kenji and Nitta finally learn about the mission they've been assigned to.

Hibito's disappearance is distracting Mutta during training and he makes a critical mistake. What will Hibito do next, and will Mutta be able to get his act together before the actual launch?
