The Vision for Space Exploration dictates retiring of the aging Space Shuttle and replacing it with a newer spacecraft, the Crew Exploration Vehicle (CEV). The CEV should be able to travel to low Earth orbit, to the Moon, to Mars and beyond. We formulate the requirements needed for the optimal design and configuration of the CEV using systematic design methodologies of Need Analysis, Function Structure generation and evolution of conceptual designs based on them. Three different concepts are formed that cater to the Need Statement and only one concept is finally selected based upon evaluation parameters, taking the Space Shuttle as the datum. NomenclatureCEV = Crew Exploration Vehicle CM = Command Module of Apollo Spacecraft ERV1 = Earth Return Vehicle 1 ERV2 = Earth Return Vehicle 2 GCR = Galactic Cosmic Radiation ISS = International Space Station LEO = Low Earth Orbit LM = Lunar Module of Apollo spacecraft MIV = Mars-orbit Injection Vehicle MRV = Mars-orbit Rendezvous Vehicle NTR = Nuclear Thermal Reactor RCS = Reaction Control System SM = Service Module of Apollo spacecraft STK = Satellite Tool Kit SS = Space Shuttle

“…A major problem in the technologies based on CO 2 electrolysis is that zirconia electrolyzers are fragile and require high operating temperatures (>1000 K). This drawback is eliminated in the second methodology [7][8][9][10][11], which brings liquid hydrogen to Mars and then uses it with the Martian CO 2 in a chemical plant to produce hydrocarbon fuel (e.g., methane, methanol, ethylene) and oxygen. The chemical plant includes a Sabatier reactor, a water electrolyzer, and may also include a reverse water-gas shift reactor.…”

“…If biogas is used properly and converted into syngas, not only would it increase the energy usage, but also decrease GHGs substantially. Applications of H 2 -rich syngas have three major purposes: polymer chemical synthesis [1], fuel cell anode reaction gases [2], and extending the flammability limits of combustion reactions [3]. While many reactors have been designed for heat recovery, in which external heat exchangers are generally used for heat transfer.…”

The subject was to design a fuel converter of CO2, focusing on parameters on thermal image observation of porous media-catalyst interface during excess enthalpy reforming process. The methodology was using auto-thermal reforming technique to provide the heat of oxidation reaction. The heat provided the needed high temperature during CO2 reduction processing. H2-rich syngas was produced by the assistance of surface reaction of catalyst. The experiments were performed by using visualization technique for thermal image observation during reforming process. The results could be applied to the understand the temperature distribution. This study covers two parts, including thermal image observation, and reactant conversion characteristics under various reforming parameters. The experimental results show that the hybrid reformer can achieve excess enthalpy condition under the tested parameters. Additionally, the optimal CH4 conversion efficiency can reach 93.28 %. CO2 conversion efficiency is reaching between 0.35 and 8.65 %. The thermal image observation technique to determine catalyst local high temperature of reforming process is important in academic and practical application. Moreover, it provided information for basic research during reforming process
