Dynamics of Laminated Plates with Layer Waviness
Composite structures usually exhibit a high strength-to-weight ratio as compared to traditional structural materials. This makes them attractive solutions in many aerospace applications....

A Membrane Structure for a Lunar Assembly Building
This paper describes potential design options and construction approaches for the development of an inflatable membrane structure of non-circular cross section. This structure could be...

Behavior of Bolted Joints in 3-D Braided Composites
As composites are used more as replacements for metals in space structures, the question arises as to the most efficient way to join the components. Mechanical fasteners are a common joining...

Late Stage Damage in G30-500/PMR-15 Laminates
Damage progression has been studied experimentally under tension using [0₂/90₆]_s...

JSC-1: A New Lunar Soil Simulant
A new lunar soil simulant, JSC-1, has been developed and characterized under the auspices of the NASA Johnson Space Center. This simulant was produced in large quantities to satisfy the...

A Simple Method of Producing Lunar Soil Simulants for Engineering Studies
This paper suggests that it is possible to obtain large quantities of simulated lunar regolith that can be used for feasibility studies of lunar base construction and excavation machinery...

Reservoir Estimates for the Sulpicius Gallus Region
Estimates presented here show that 1.1?10⁹ metric tons of oxygen could of produced from one of the enriched areas that have been detected by spectrographic...

Feasibility of Dual Technology in Manufacturing Lunar Concrete
This paper presents the feasibility of utilizing different construction materials for probable use on the moon. Furthermore, it is to our advantage to use what is available on the moon...

Utilization of Liquid Carbon Dioxide for Planetary Exploration
The major component of the atmosphere of Venus and Mars is carbon dioxide CO₂. This proposal is to use this carbon dioxide for planetary exploration...

Lunar ISRU: An Evolutionary Approach
The goal of this paper is to provide the reader with a vision of the individual steps required to bring ISRU from the current technological readiness level of lab experimentation, to large...

Terrestrial Analogs: Implications for Lunar Lava Tubes
Earlier work has demonstrated that lava tubes did form on the Moon. Comparison of terrestrial lava tubes to their lunar counterparts suggest that they are very similar despite the order...

Lunar Oxygen Production - A Maturing Technology
Research on oxygen production from lunar rock and soil has made significant progress in the past two years. An extensive series of experiments on natural and synthetic analogs has concentrated...

Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...

Lunar Oxygen Production in a Hydrogen Cold Plasma
This paper examines the concept of oxygen production from unbeneficiated lunar regolith using a non-equilibrium or 'cold' hydrogen plasma. An experimental investigation has indicated that...

Carbon Formation Theory for Space Oxygen Processes
Production of oxygen from the Martian atmosphere or lunar soil and the recovery of oxygen in manned space environments may include carbon formation from CO as a unit process. Thermodynamic...

Oxygen from Lunar Soil via Fluorination
This paper considers oxygen extraction from lunar soil via fluorination, for reasons of its high effectivity of oxygen release from most silicates. In addition to theoretical investigations,...

Sintering Bricks on the Moon
Sintering of full-scale 'bricks' from lunar soil simulant materials can be accomplished by radiant heating to 1100?C for approximately 2 hours, followed by slow cooling. Small-scale precompaction...

Analysis of Glass-Ceramic Production from Lunar Resources
Two simulated regoliths were used to investigate the effects of processing and composition on the properties of lunar-derived glass-ceramics. For the simulant with moderate iron concentration,...

Fiber Optic Chemical Sensors on Mars
A fiber optic chemical sensing instrument is described that will measure the reactivity of the martian soil and atmosphere. The self-contained instrument monitors reflectivity changes...

Design of Mat Foundation for Egg Shape Digesters
Two levels of ground motion, the Maximum Probable Earthquake and the Maximum Credible Earthquake, were considered in designing the 2.5 million gallon egg shape digesters and their combined...
