Hibito and the CES-51 crew have landed on the moon. Meanwhile, Mutta has returned to Japan to await his final exam results. He's especially concerned about using up his luck before the results are announced.

Mutta and the other astronaut candidates have finally finished their Japanese training. Before they head to Houston, they receive a gift from Director Nasuda.

Mutta and Hibito are selected for a magazine cover. Mutta is excited, but he notices that Hibito is acting strangely.

Mutta's idea for improving the lunar rover has earned him the right to participate in NEEMO training. He has taken one step toward the moon.

As Sharon makes a new proposal to NASA for the lunar telescope, Mutta continues his training in the desert. However, Chief Butler is still seeking a backup captain for the mission.
