The document summarizes the Ares I integration approach for launching the Orion spacecraft. It describes the key elements and configuration of the Ares I rocket, including the first and upper stages. It also outlines the vehicle integration organization and control processes for integrating the different components. Finally, it provides an overview of some of the engineering responsibilities involved in Ares I integration like aerodynamics, loads, guidance and flight control systems.
