Powerful new computational tools and small, expert teams have produced unprecedented levels of design detail in the latest cycle of engineering planning for human expeditions to Mars. This article reports on a study contract for NASA-MSFC which evolved mature fourth-generation Mars mission vehicle concepts, a set based on nuclear electric, solar electric, and nuclear thermal propulsion methods. The concept described in this article covers propulsion vehicle and lander design, transfer vehicle design, engines and propulsion components, crew habitats, and the earth-to-orbit (ETO) flight plan. The vehicle design integration has taken full advantage of modern numerical capabilities, including the following: supercomputer flight dynamics calculations; automated radiation dose analysis; and computer-aided design, drafting, performance modeling, and image representation. Fourth-generation methodology has established a challenging benchmark against which future concepts will be judged.
