This paper presents a preliminary modeling method, Habitat Multivariate Design Model (HMVDM), to estimate the volume, size, shape, and configuration required for the design of a space habitat. The specific habitat used for this analysis is the “Habot” mobile lunar base concept. The HMVDM methodology begins with values for mass and volume from quantitative summation tools such as the NASA Office of Biological and Physical Research (OBPR) Crew Accommodations Guide. From these tools, it derives a more detailed analysis of mass and particularly of volume. The estimated volume is input into the model, written as a spreadsheet-based analytical modeling tool. In this pilot study, the diameter of a cylindrical module serves as the single independent variable.

The ability for crewmembers to explore the surface of the Moon or Mars effectively on foot remains a significant test of any exploration design. The availability of a pressurized rover would substantially increase the range of exploration by space suited crewmembers. The design of the airlock systems or functions will facilitate crewmembers in accomplishing these efforts. The pressurized rover for planetary exploration incorporates three types of airlocks or pressure ports: the EVA airlock, the sample airlock and the habitat docking port. This paper conducts a survey of selected precedents in pressurized rover design and then analyzes the key issues for airlock design.

The crucial challenge to astrobiology research on Mars is for the astronaut crews to conduct the search for life past and present from a Mars surface base. The Mars base will require a highly specialized astrobiology science laboratory to facilitate this research. This paper presents an incremental strategy to develop the laboratory technology and facility necessary to enable the astrobiology investigation on Mars. The distinguishing characteristic of an astrobiology research apparatus for the Mars surface science laboratory is that the research crew must work across a large pressure differential between the shirtsleeves cabin atmosphere and the Mars ambient atmosphere inside the apparatus. How to simulate that apparatus and its operations through Earth expeditions is an essential aspect of design development.
