Extraction of Light Gasses from Mars or its Moons
The light elements H, C, N, O and S are important for propellant production and life support in space. These light elements occur on Mars, and may occur on the martian moons Phobos and...

A Commonality Assessment of Lunar Surface Habitation
This paper presents a commonality assessment of lunar surface habitation. Thus far, NASA has baselined the space station common module for initial lunar base habitation; however, nothing...

Extraterrestrial Applications of Solar Optics for Interior Illumination
The major purpose of this paper is to introduce a terrestrial technology that we believe has potential extra-terrestrial applications. The technology is Solar Optics, which is subdivided...

Design Requirements for a Mars Base Greenhouse
One potential method of supplying life support to a manned base on Mars utilizes a Controlled Ecological Life Support System (CELSS). A major component of the CELSS is a plant growth unit...

Power Systems for Production, Construction Life Support, and Operations in Space
As one looks forward to mankind's future in space, it becomes obvious that unprecedented amounts of power will be required for the exploration, colonization, and exploitation...

Supercritical Water Oxidation: Space Applications
The process of Supercritical Water Oxidation (SCWO) is approaching terrestrial commercialization for the destruction of toxic and hazardous waste chemicals. The technology appears promising...

Development of a Two-Stage Membrane-Based Wash-Water Reclamation Subsystem
A two-stage membrane-based subsystem was designed and constructed to enable the recycle of wash waters generated in space. The first stage is a fouling-resistant tube-side-feed hollow-fiber...

Waste Management: Project Mercury to the Space Station
This paper presents my perceptions of the design of waste management systems for manned space flights. I'll follow the evolution of waste management from the early Mercury...

Wastewater Recycle/Reuse: Lessons-Learned from USA-CERL Research and Development
Ultimate acceptance of water recycle/reuse by the scientific community is a function of rigorous data collection and successful demonstration regarding health effects. An uncomplicated,...

Gas Recycling: A Bioregenerative Life Support System
The prospect of a lunar or earth-orbiting space station raises the question of life support for long periods of time with little or no support from earth. The cost of lifting supplies...

Potential Application of Space Station Technology in Lunar Bases and Manned Mars Missions
To meet the goals of its Space Station program, NASA is developing a large set of improved space systems capabilities. In areas such as power generation and distribution, on-board data...
