This article discusses state-of-the-art crawler transporters and expresses the need for additional research and development for lunar crawlers. The thrust of the paper illustrates how...
Construction of a Far-Term (2020+AD) Lunar Base
Several case studies have been performed which provide interesting insights into the design and operation of a lunar base. Yet few of these studies have addressed the specific steps which...
Construction Challenges on Planetary Surfaces
In July 1989 those who advocate a vigorous U.S. space program received a significant boost from the President's declaration that we should return to the Moon, this time to stay, and then...
The Application of Open System Architecture to Planetary Surface Systems
This paper investigates the issues that future planet surface activities must confront, defines the basic concepts that provide the basis for establishing an Open System Architecture,...
Lunar Resource Base
A lunar base that exploits local resources to enhance the productivity of a total SEI scenario is discussed. The goals were to emphasize lunar science and to land men on Mars in 2016 using...
In-situ Release of Solar Wind Gases from Lunar Soil
A concept is described which has the potential to perform the in-situ heating of the lunar regolith in order to release the solar wind gases. The poor thermal conductivity of the lunar...
Isotopic Separation of ?He/4He From Solar Wind Gases Evolved from the Lunar Regolith
The potential benefits of 3He when utilized in a nuclear fusion reactor to provide clean, safe electricity in the 21st century for the world's inhabitants...
Assessing Lunar Resources with Remote Sensing
Four strategic architectures have been identified as part of the U.S. Space Exploration Initiative (SEI) to achieve U.S. goals with respect to the Moon. One of these architectures, space...
A Modified Sulfate Process to Lunar Oxygen
A modified sulfate process which produces oxygen from iron oxide-bearing minerals in lunar soil is under development. Reaction rates of ilmenite in varying strength sulfuric acid have...
Evaluation of Processing Options for Lunar Oxygen Production
Recent work on space resource utilization has lead to the identification of certain modifications of previously proposed processes which can be properly characterized as 'second generation'...
Materials and Structures Synergistic with In-Space Materials Utilization
The objective of this paper is to clearly demonstrate the significant advances made in recent months toward actual hardware realizations of various concepts for the utilization of in-space...
The Feasibility of Processes for the Production of Oxygen on the Moon
Twenty different processes for the production of oxygen on the Moon have been proposed. An evaluation of their perceived feasibility is presented. The lunar liquid oxygen (LLOX) production...
On-Orbit Chipless Cutting and Tube Welding in Space Station Freedom
Micro-gravity and strict environmental constraints of the laboratory, Habitation and other manned structures which comprise Space Station Freedom demand investigation into innovative processes...
Transient Analysis of Flexible Space Structures
A new approach for numerical analysis of flexible space frames subjected to impact forces is presented. The method is particularly effective in the analysis of large amplitude vibration...
Structural Design of the GN&C Navigation Base for the Space Station Freedom
The Space Station Freedom (SSF) pointing accuracy budget requires that the Guidance, Navigation and Control hardware maintain alignment within ? 0.1 degrees of arc. The ring laser gyros...
A Novel Aerobrake Design for a Mars Lander
A flexible/inflatable aerobrake is proposed for delivering small payloads to Mars as an alternative to propulsion landing. Some results that demonstrate feasibility are presented....
Structural Considerations in the Design of a Mars Mission Aerobrake
A new area of civil engineering is emerging. This area will provide structures for outposts on the moon, resource development and exploration of Space. Spacecraft traveling at very high...
Response of Space Structures Under Sudden Local Damage
Damages to space structures can come from such adverse events as impact by foreign objects, docking, drastic temperature changes, and exposure to radiation and charged particles. This...
