ArmorHab mission architecture for Mars Colonization

The innovative ArmorHab mission architecture was presented at the Mars Society Conference in 2016. This novel approach should be considered as part of a strategy for settlement of the Red Planet. The concept integrates several engineering solutions for habitat design to address radiation protection, life support, and transportation while leveraging in situ resource utilization to enhance crew health, safety and reduce costs.

The basic building block of the architecture is a cylindrical Mylar shell wrapped in superconductive tape providing radiation protection through emulation of a magnetosphere. This structure is encased in a protective aerogel for strength and insulation including layers of water ice to further protect the crew from micrometeorites and algae bioreactors for scrubbing carbon dioxide for life support.

Leveraging Buzz Aldrin’s Mars Cycler invention, the plan starts by building out infrastructure in cislunar space including automated factories on the Moon, then expanding out to Mars with space stations, cycling habitats and connecting “trucks” to provide transport to and from the surface of each destination.

Ceres megasatellite space settlement

Pekka Janhunen of the Finnish Meteorological Institute, Helsinki, Finland has just posted a paper on the arXiv server describing his concept for a megasatellite space settlement in orbit around Ceres and constructed from materials from this dwarf planet in the asteroid belt. Ceres is chosen because of the availability of nitrogen and water needed for life support. A space elevator is proposed as an efficient means of lifting materials off the surface.

Janhunen works out the physics and mass budgets for a collection of settlements comprising the megasatellite, each providing 1g artificial gravity and a closed-loop life support system. The assemblage is made up of a collection of self contained rotating habitats which are interconnected and could potentially grow to house billions of people with 2000 square meters of living area per person. Each habitat would include soil thick enough to enable biomes with trees and ideal weather.

SSP covered another free space settlement concept by this author last April a bit closer to home at L5 in the Earth-Moon system. Janhunen discussed this duel-dumbbell design on The Space Show in May of last year.

Determining the Gravity Rx

Joe Carroll of Tethers Applications, Inc. delivered a presentation on a proposal for a LEO partial gravity test facility at the StarShip Congress which took place in San Diego September 13 – 15. An interesting fact is that of all the surfaces of bodies in the solar system where humans may want to build settlements, all of them have gravity similar to the Moon and Mars. Thus gravity in the solar system is “quantized” to just these two levels simplifying the testing regime. Determining the prescription needed for human health in partial gravity is a critical path research topic needed for space settlement.
