Aeronautics Research: Research and develop aeronautical 
        technologies for safe, reliable and efficient aviation systems 
        
Science: Carry out the scientific exploration of the Earth, Moon, Mars 
          and beyond; chart the best route of discovery; and reap the benefits 
          of Earth and space exploration for society. A combined organization 
          is best able to establish an understanding of the Earth, other planets 
          and their evolution, bring the lessons of our study of Earth to the 
          exploration of the Solar System, and to assure the discoveries made 
          here will enhance our work there 
        Exploration Systems: Develops capabilities and supporting research 
          and technology that enable sustained and affordable human and robotic 
          exploration; includes the biological and physical research necessary 
          to ensure the health and safety of crew during long duration space flight
        Space Operations: Direct space flight operations, space launches and 
          space communications, as well as the operation of integrated systems 
          in low-Earth orbit and beyond.
