Take a high school course load that's heavy in science, math and industrial or technical arts.
Enroll in a bachelor's degree program in aerospace, aeronautical or other related engineering program such as mechanical, structural or electrical engineering.
Decide which of the following areas you want to specialize in: propulsion, flight and space mechanics, fluid mechanics, thermodynamics and aerodynamics. As you progress in your bachelor's degree program you'll begin to refine your area of interest.
Search for and apply to several schools that offer a master's degree in aeronautical or aerospace engineering. Purdue University in Indiana, University of California, San Diego, and Embry-Riddle Aeronautical University in Florida are just a few of the many credible schools offering master's degrees in your field across the nation.
Take the GRE exam and have your scores sent to the schools you applied to.
Finish your course work, which will include courses in the field of aeronautical and astronautical engineering. Typical programs consist of 10-12 courses and may or may not require the completion of a thesis paper. Check with your specific school for details.
