Best Courses for Astronautics

Hey everyone! I'm a high school sophomore (gonna be a junior next year) and I'm not sure which classes to take that will best prepare me for being an Astronautical engineer. Would it be better to take design courses (Principles of Engineering, CAD, etc.) or computer classes (Java, AP Computer Science A, AP Computer Science Principles, etc.)? Any recommendations would be greatly appreciated. If you have any suggestions for classes to take or summer programs to help me prepare, feel free to comment Thanks in advanced!
