ArmorHab architecture aims to develop long term habitats, constructed primarily (>50%) from in-situ resources of planetary bodies, using synthetic magnetospheres for shielding, providing protection for each type of habitat: transport, orbital, and surface habitats. The ArmorHab architecture adapts to the challenges of extraterrestrial environments (extremes of temperature, pressure, radiation, etc.) using a combination of existing and new technologies. We maintain breathable air with redundant biological and mechanical systems, self-sealing walls which protect against micro-meteoroid punctures, and defense in-depth by using multiple sealed chambers with connecting airlocks. In low-gravity conditions, gravity is emulated through centrifugal force. Radiation shielding is provided by magnetosphere emulation using steady-state superconductive cables. Food production uses aeroponic and hydroponic industrial scale facilities, including lab-grown meats. The crew is busy with commercially productive mining, manufacturing, and base/station operations, including food production. Thermal isolation from the environment uses a combination of IR reflective films, thermal mass, and aerogel insulation. Structural components are built from in-situ materials using additive manufacturing and other advanced techniques. All of the components of the ArmorHab architecture serve multiple purposes: a layer of ice will provide self-sealing micrometeorite defense along with supplementary radiation shielding and water storage; structural reinforcement of the habitat will play a role in forming the artificial magnetosphere; algae bioreactors and radiation-resistant plants will scrub carbon dioxide and pollutants, produce biomass that will be utilized, and provide additional radiation protection.

NewSpace bears all the hallmarks of past revolutions in technology. Since we have other examples of exponential growth of specific technologies, we should maximize the economic and engineering potential of this movement by expanding the envelopes for long term crewed habitats in deep space. We should also take an approach that minimizes waste in both design and fabrication as these bases expand. This paper provides a systematic approach to habitats optimized for volume, radiation protection, crew psychology, reusability, affordability, crowd-sourced subsystem design, and expansion. These habitats and systems are designed to be as “future proof” as possible to allow rapid and safe technological advancement within the structures. One of major “showstoppers” of human space exploration is cosmic and solar events radiation. It is a serious problem that may cause cancer and other types of tissue damage and equipment malfunction. It has to be addressed in space vehicles design especially f...

One major obstacle to human space exploration is the possible limitations imposed by the adverse effects of long-term exposure to the space environment. Even before human spaceflight began, the potentially brief exposure of astronauts to the very intense random solar energetic particle (SEP) events was of great concern. A new challenge appears in deep space exploration from exposure to the low-intensity heavy-ion flux of the galactic cosmic rays (GCR) since the missions are of long duration and the accumulated exposures can be high. Because cancer induction rates increase behind low to rather large thickness of aluminum shielding according to available biological data on mammalian exposures to GCR like ions, the shield requirements for a Mars mission are prohibitively expensive in terms of mission launch costs. Preliminary studies indicate that materials with high hydrogen content and low atomic number constituents are most efficient in protecting the astronauts. This occurs for two...

Radiation shielding aspects for long manned mission to space: Criteria, survey study, and preliminary modelThe prospect of manned space missions outside Earth's orbit is limited by the travel time and shielding against cosmic radiation. The chemical rockets currently used in the space program have no hope of propelling a manned vehicle to a far away location such as Mars due to the enormous mass of fuel that would be required. The specific energy available from nuclear fuel is a factor of 106 higher than chemical fuel; it is therefore obvious that nuclear power production in space is a must. On the other hand, recent considerations to send a man to the Moon for a long stay would require a stable, secured and safe source of energy (there is hardly anything beyond nuclear power that would provide a useful and reliably safe sustainable supply of energy). National Aeronautics and Space Administration (NASA) anticipates that the mass of a shielding material required for long travel to Mars is the next major design driver. In 2006 NASA identified a need to assess and evaluate potential ga...
