Astrid is training to go to space! But as she builds her shuttle, cooks astronaut food, and practices floating in zero gravity, Dad tells Astrid that the ship's construction is too dangerous, she's too little to cook alone, and she's not allowed to flood the bathroom. That night, when Astrid dreams she's an astronaut, the challenges she encounters are overwhelming. Astrid realizes she isn't as ready as she thought. Back on Earth, Astrid turns to her loving and supportive Dad, who helps Astrid continue her astronaut training.
