On Hibito's first return to zero-gravity training on Earth, he suffers a panic attack when lowered into the water in a space suit. Since astronauts are required to be able to perform EVAs, NASA denies him new lunar missions until he's completely recovered. Determined to do so, Hibito confides in Sharon, but asks to keep it a secret from his family and colleagues. Meanwhile, Mutta consults with Damien on how to improve the lunar buggy, and decides to leverage his old automobile industry connections for assistance.
