“…With the versatility of the Mobile Base approach, it is possible to land new mobile modules with new equipment, supplies or logistical support in the path of the moving ensemble. These new units could then join the "wagon train" to continue on the journey, or simply provide a cache of supplies for the crew to pick up along the way (Cohen, 2003).…”

This paper describes three innovative concepts for a mobile lunar base. These concept combine design research for habitat architecture, mobility systems, habitability, radiation protection, human factors, and living and working environments on the lunar surface. The mobile lunar base presents several key advantages over conventional static base notions. These advantages concern landing zone safety, the requirement to move modules over the lunar surface, and the ability to stage mobile reconnaissance with effective systemic redundancy. All of these concerns lead to the consideration of a mobile walking habitat module and base design. The key issues involve landing zone safety, the ability to transport habitat modules across the surface, and providing reliability and redundancy to exploration traverses in pressurized vehicles. With self-ambulating lunar base modules, it will be feasible to have each module separate itself from its retro-rocket thruster unit, and walk five to ten km away from the LZ to a pre-selected site. These mobile modules can operate in an autonomous or teleoperated mode to navigate the lunar surface. At the site of the base, the mobile modules can combine together; make pressure port connections among themselves, to create a multi-module pressurized lunar base.

“…After the crew departs in the CEV ascent stage, the Habot base can disassemble itself and travel autonomously 100km or more to a new site of scientific interest. There, the Habots reassemble the base, connect, pressurize the port connections, and verify readiness and safety, the second crew lands in a CEV lander, The Advanced Projects Branch at NASA-Ames Research Center is working to substantiate the Habot as a candidate lunar surface base architecture (Cohen, 2003(Cohen, , 2004. Radiation shielding is a critical component of the Habot and any interplanetary vehicle or Mars surface habitat.…”

Carbon Radiation Shielding for the Habot Mobile Lunar Base

Radiation is the leading showstopper for long duration human exploration of the lunar surface. The need for an effective and safe radiation shielding material has become the "Holy Grail" of radiation protection research. This paper reports the results for one material in particular-carbon-in the "Bioshield" particle accelerator test of candidate radiation shielding at Brookhaven National Laboratory, sponsored jointly by NASA and the Italian Space Agency. Shielding samples were bombarded by both Iron and Titanium nuclei beams at1 GeV/n relativistic energy. This paper reports the results for Fe. The target behind the shielding was a lymphocyte culture; created using advanced cytogenetic techniques (premature chromosome condensation and fluorescence in situ hybridization). The shielding samples included aluminum, PMMA acrylic/Lucite, polyethylene, and lead. The Habot Mobile Lunar Base Project at NASA-Ames Research Center provided the carbon-shielding sample because of its potential to provide a suitable shielding material to apply to the exterior of the Habot. The specific material tested is "CCAT CC-1, Carbon-filled carbon." This particular formulation has the advantage that the manufacturer controls the density to .01 g/cm 3. The density of this sample is 1.65 gm/cm 3. The carbonfilled carbon performed successfully, providing the second best dose reduction after polyethylene and the best overall reduction in radiobiological damage to the lymphocyte culture. This experiment suggests that carbon composites present important advantages for space habitat construction.

This study presents an architectural analysis of the base configuration concepts and options for the Habot Mobile Lunar Base. "Habot" is a contraction of Habitat and Robot. The analytical technique consists of a systematic comparison of the various configurations at several scales. These scales include the overall configuration of the base cluster; the architectural plan and sections of the Habot modules; the pairing and adjacency relationships among modules; the implications for structural details of the module pressure vessels; and the thermal control/heat rejection system. The evaluation criteria include complexity; mass of redundant overhead hardware; efficient use of floor area; useful allocation of equipment volume; and effectiveness of the circulation pattern. A major consideration is that the functional purposes of each Habot unit pose different demands and implications for the design. The minimum set of Habot unit functional types are: living/habitat unit, laboratory unit, logistics unit, EVA access/ airlock/ excursion port, and excursion Habot. The key finding of the study is that a simple linear arrangement of Habot units, with the EVA Access/ excursion port units at either end, is the most efficient. It is the most efficient at nearly all levels of the analysis, but most especially in the advantages for useable floor area, equipment volume, and avoidance of excessive circulation area and unnecessary design complications. * Aerospace Engineer --Flight System Design and Architect, retired, AIAA Associate Fellow.
