The JAXA astronaut candidates head to Houston, to begin training at NASA. However, Murakami-san appears to have a surprise in store for Mutta.

After Mutta takes a make-up exam, this time managing to concentrate properly, he once again meets Deneil Young. With the top scoring AsCans being assigned to the best flight instructors for their T-38 training, Mutta, as the only one who had to take a make-up, is assigned to Deneil.

Mutta comes up with an idea to prevent vehicular accidents on the moon. Will NASA accept his proposal?

Only one of each team's two Ants will be chosen to go to the moon. Since the beginning of his journey, Mutta has worked with Kenji, so he isn't sure what to do.

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.
