The authors of this document recommend that, to enable missions to the moon and Mars, NASA's Constellation vehicles, habitats, and spacesuits employ an integrated set of internal atmospheres rather than a single design for all elements. These atmospheres must mitigate the risks of fire, decompression sickness, and hypoxia while enabling crew excursions on planetary surfaces. It should be noted that the recommendations provided in this document are not requirements; instead, they reflect technical considerations only. To support the recommendations made herein, Constellation should institute a modified standard NASA flammability test as soon as possible to generate ignition threshold data for key spacecraft materials. This modified test will allow the agency to identify materials at risk from increases in oxygen concentration, minimize potential impacts, and allow for development of sound requirements for landers and habitats. The Human Research, Technology Development, and Constellation Programs should also initiate activities to enable atmosphere designs for, respectively, human research, technology development, and program-specific studies to validate these recommendations for the Constellation habitable elements.
