Requirements and Concept for an On-Orbit Construction Facility for Phase 1 Space Station Freedom
Future NASA plans for exploring the solar system and programs such as the Large Deployable Reflector and Pathfinder require in-space construction for their success. The technologies required...

Incident Solar Flux at Fixed Orientations
Optimal orientations are computed to maximize or minimize the incident solar flux onto surfaces on spacecraft at fixed attitudes. This analysis was motivated by a potential need to optimize...

Space Debris—A Design Consideration
With the increased use of space by manned or unmanned missions, it has become necessary to include yet another parameter in the design of spacecraft, namely, the effect of a probable impact...

Man-Made Debris Environment Characterization for Spacecraft Vulnerability Assessment
An issue of growing importance in the study of orbital debris is the need to understand the consequence of impact on a space structure. In this paper, a technique is developed to analyze...

Clearing Space Debris Using Energetic Materials
Space debris is growing at an alarming rate. It consists not only of old, unusable payloads but also aluminum oxide combustion products of various space delivery systems and small fragments...
