A New Airlock Approach for Human Exploration
Conceptual design work on the First Lunar Outpost (FLO) mission led to the development of an airlock concept called the `doorlock' which appears quite promising for all aspects of manned...
Damage Tolerance of Thin Composite Reinforced Membrane Structures
Structural performance of fiber reinforced flexible composite membranes, designed as pressurized shelters for space exploration, is investigated via computational simulation. An integrated...
Optical Scatter From a Space Craft Mirror Due to Microscopic Impacts
This article addresses the issue of how micrometeoroid and man made debris in the space environment can adversely change the optical resolution of a mirror. The study used an algorithm...
The Effect of Mobile Transporter Motion on the Space Station Attitude Control System
The effect of Mobile Transport (MT) motion on Space Station stability and the performance of the Attitude Control System (ACS) using Control Momentum Gyros (CMGs) is assessed. Analysis...
A Space Station Simulation: EXEMSI '92 A Study on Confinement and Isolation of a Mixed Crew of Four during 60 Days
Manned spaceflight is entering a new era. The next period will be characterized by long duration stays in space and heterogenous crews. EXEMSI '92 was an attempt to study the human-related...
Global Environmental Change: Geoengineering Technology
The `overview effect,' looking at the entire Planet Earth from space, has communicated the reality of the limited extent of our environment and its apparent fragility. Space continues...

Is It Possible to Colonize Mars?
Is it possible to colonize the planet Mars? A planet that is believed to be the most clement planet in the solar system, next to Earth. Despite the fact that it is a very clement planet,...
Construction of a Lunar Base
The United States' space program has the capabilities to build a lunar base, but must build an infrastructure which allows the easy transportation of the construction materials. Once this...
Space Exploration: Getting a Handle on Why?
The two prominent economic issues facing the U.S. today are competitiveness and the huge federal deficit. Economics being the counter-intuitive science that it is, a reasonable exploration...
