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...

A Study of Communication Signal Leakage Through the Earth's Ionosphere Using Ray-Tracing Techniques

Inter-stellar Propulsion: The Need for Speed
Interstellar travel is certainly one of mankind's next step to reach for the stars. Four ideas for interstellar propulsion are discussed in this paper: the Orion Project, Deep Space Ramjets,...

Space Stations Past, Present, and Future
The paper discusses the evolution, present state and future of space stations. Man's interest in the stars led to many inventions and the ultimate launching of the Russian satellite Sputnik,...

The Effect of Zero Gravity on Bones
Zero-gravity has created many problems for astronauts and researchers in space. Calcium depletion is cited as a major health problem. There are many different theories as to why zero-gravity...

Dust Levitation on the Moon
The NASA sponsored Lunar Base Working Group at the Institute for Astrophysics, University of New Mexico and the Department of Astronomy, New Mexico State University has been investigating...

Science Operations and Engineering Impacts to Lunar Outpost Design
Recent work by scientists and engineers at the Johnson Space Center ha led to a better understanding of the requirements and interfaces needed at an initial lunar outpost to enable scientific...

Very Low Frequency Radio Astronomy from Lunar Orbit
This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy...

An Inflatable Antenna for Space-Based Low-Frequency Radio Astronomy
Antennas for a low-frequency orbiting radio telescope must have minimal problems in deployment, a directional beam, and a wide-angle scanning capability. Inflatable antennas with deposited...

Development of a High Resolution Spectrometer for Measuring the Near-Earth RFI Environment: The First Auto-Correlator in Space
A detailed description of the near-Earth RFI (radio frequency interference environment in the 0.5 - 16.5 MHz range is required before low frequency arrays can be designed and implemented...

The Lunar Ultraviolet Telescope Experiment (LUTE)
The Lunar Ultraviolet Telescope Experiment (LITE) is a feasible scientific payload which could initiate a unique ultraviolet (UV) sky survey from the lunar surface prior to our manned...

Gravitational Wave Astronomy and the Lunar Ligo Concept
The preliminary proposal (LaFave and Wilson, 1993, 1992) for emplacing a modest LIGO [ Laser interferometer Gravitational Wave Observatory ] system on the Moon using unmanned robotic landers...

Low Frequency Radio Astronomy from Earth or Lunar Orbit
Acquiring data at low frequencies is complicated by the fact that the ionosphere strongly disturbs the data, especially for high-resolution ground-based telescopes. The most viable observational...

Operations Analysis for a Large Lunar Telescope
With the launch of the Hubble Space Telescope a new generation of science optical observatories was made a reality. Astronomers and scientists have long seen space as having inherit advantages...

Assessment of a SSF Servicing Facility
Evolution options for a servicing facility at Space Station Freedom (SSF) are currently being studied. While many choices exist, one promising idea is an enclosed facility or hangar which...

Pressure Suit Requirements for Moon and Mars EVA's
In this paper, we examine the influence of pressure suit and backpack designs on astronaut productivity and on the frequency with which EVA's can be conducted during lunar base operations...

The Proposed NASA Lunar-Based Astronomical Observatories
The goals of the Space Exploration Initiative are a manned return to the Moon, a permanent lunar outpost and then a manned expedition to Mars. This presents an opportunity to construct...

System Concepts for a Series of Lunar Optical Telescopes
The Lunar Telescope Working Group of the Marshall Space Flight Center (MSFC), NASA, has conducted conceptual studies of an evolutionary family of UV/optical/IR telescopes to be based on...
