Modeling and Analysis of Doubly Curved Aerobrake Truss Structures
Recent studies have indicated that vehicles designed for a piloted mission to Mars may have their initial Earth Orbit mass reduced by nearly a factor of two if aerobraking is used rather...
The Affordable Space Platform: The STS External Tank
Future development of space requires establishing affordable work platforms in orbit. This paper surveys possible uses of the Space Transportation System's External Tank (ET) to provide...
Impact Craters on Cosmic Dust: Do Damage to the Spacecraft
The discovery and study of impact crater on cosmic dust to understand the overall micrometeoroid environment and space engineering requirement are important. In this paper, we attempt...
Evolution of the Space Station Freedom Module Pattern
The Space Station Freedom (SSF) is being designed to serve as a permanently manned platform in space to accommodate a growing amount of supported scientific research and, ultimately, to...
On-Orbit Assembly of Large Space Structures: A Mars Aerobrake Mock-up Study
As design requirements for space structures become larger in dimension, the issues of shipping and assembling these structures in space become more critical. One example of such a structure...
Structural Design Methodology of Large Space Structures
This paper discusses considerations and outlines a methodology for structural design of large space structures (LSS) deployed in low earth orbit. It includes definition of mission requirements,...
A Methodology for Development of Spaced-Based Assembly Operations
Designing and constructing a large space-based science facility requires the integration of constraints and design variables with assembly operations. Development of such a facility requires...
Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...
Explosive Forming of Aluminum-Lithium Alloys
This paper proposes the use of explosive forming to form large, near net shape components for HLLV propellant tanks and structures in meeting this need. Combining with high strength to...
The Analysis Related to the Impact of Composite Panels
In analyzing experiments under impact loading, a dynamic model is needed to solve for the deflections and strains as functions of time. For composites, where shear deformation can be very...
Composite Materials for Structures on Planetary Surfaces
Development of structures for planetary surface environments depends upon the use of the most appropriate materials. Advanced composite materials are apparently the best candidates for...
Optimum Design of Laminated Composites
The increased demand for high strength, light weight materials that function successfully in high temperature environments has caused the effective development of laminated composites...
Modular Robot Testbed
One approach to non-terrestrial construction involves the use of small, inexpensive, modular robots rather than expensive one-of-a-kind construction tools. The Modular Robots Testbed at...
A New Era in Space Operations
The United States has embarked on a bold new course in space. We are in the process of deploying global missile defenses which promises to help realize an extended era of international...
Operations Planning for Space Station FREEDOM?and Beyond
Automated planning and electronic execution systems offer tremendous potential for enhancing operations aboard Space Station FREEDOM (SSF). To exploit this potential, the Operations Planning...
Advances in Ground Operations for the Next Generation Space Launch Vehicle Programs
For over thirty years, large launch vehicles such as Saturn, Delta, Atlas, and Titan have successfully provided the world with access to space. The emphasis of each of those programs was...
Architectures for Mission Control at the Jet Propulsion Laboratory
One of the most vital, but often overlooked, research areas for space missions is flight operations. The imbalance is caused by many factors. Among them, the manner in which space missions...
Thermal Investigation of a Large Lunar Telescope
Recent interest in construction of a large telescope on the Lunar surface (Nein and Davis, 1991; Bely, Burrows, and Illingworth, 1989) has prompted this feasibility study of a thermal...
Concept for a Lunar Array for Very Low Frequency Radio Astronomy
We discuss the design considerations relevant to a very low frequency array, to be deployed on the lunar near side during an early expedition. Such an array would operate in the frequency...
Laboratory Evaluation of Footings for Lunar Telescopes
Presented here are the results of laboratory experiments with different footing shapes for lunar telescopes. These experiments used a variety of soils including some to simulate regolith...
