The variety of mission architectures currently under consideration presents aerobrake designers with an enormous range of potential entry scenarios. Two of the most important considerations in the design of an aerobrake are the required control authority (lift-to-drag ratio) and the aerothermal environment which the vehicle will encounter. Therefore, this study examined the entry corridor width and stagnation-point heating rate and load for the entire range of probable entry velocities, lift-to-drag ratios, and ballistic coefficients for capture at both Earth and Mars. To accomplish this, a peak deceleration limit for the aerocapture maneuvers had to be established. Previous studies had used a variety of load limits without adequate proof of their validity. Existing physiological and space flight data were examined, and it was concluded that a deceleration limit of 5 G was appropriate. When this load limit was applied, numerical studies showed that an aerobrake with an L/D of 0.3 could provide an entry corridor width of at least 1 degree for all Mars aerocaptures considered with entry velocities up to 9 km/s. If 10 km/s entries are required, an L/D of 0.4 to 0.5 would be necessary to maintain a corridor width of at least 1 degree. For Earth return aerocapture, a vehicle with an L/D of 0.4 to 0.5 was found to provide a corridor width of 0.7 degree or more for all entry velocities up to 14.5 km/s. Aerodynamic convective heating calculations were performed assuming a fully catalytic, 'cold' wall; radiative heating was calculated assuming that the shock layer was in thermochemical equilibrium. Heating rates were low enough for selected entries at Mars that a radiatively cooled thermal protection system might be feasible, although an ablative material would be required for most scenarios. Earth return heating rates were generally more severe than those encountered by the Apollo vehicles, ...

Book excerpt: How feasible is a manned Mars flight? How soon will it be possible? How long will it take? What kind of spacecraft will make the journey? What kind of data will be collected? What are the advantages of a manned flight over an unmanned? Mission to Mars discusses these questions and more in this serious, documented treatment of the not-too-distant manned expedition to Mars. The shuttle has proved successful and an enthusiastic boost to American interest in space. But while many laypeople wonder “what’s next,” scientists are planning what they feel is the next logical step. Drawing on the vast amount of data sent back by Viking orbiters and probes, and existing developments in propulsion and space technology, space experts all over have been speculating, analyzing, and exchanging ideas relative to the long-awaited mission to Mars. Other factors, critical to an intelligent discussion of such an undertaking are included here: spaceship design and assembly, propulsion systems, navigation principles, life support systems, selecting a landing site, scientific activities on Mars, cost factors, political and social issues.

Book excerpt: Twenty-six essays written by workers in the space industry and interested lay people make a case for exploring Mars, arguing for the scientific objectives that could be achieved in the Martian "frontier" and even providing a cost and benefit analysis. The discussions suggest specific strategies in "getting there," flight profiles, and rocket designs utilizing nuclear electric propulsion. However, the questions remains--what happens when we arrive? In response, the authors speculate on life support, biomedical issues, transportation, and living spaces based on Biosphere 2 results. Lacks an index.
