LIAC: A Closed Ecosystem Research Facility
A preliminary design for a closed research facility capable of supporting multispecies and ecosystem level experiments is presented. This project will support NASA's Controlled Ecological...

An Integrated Human/Plant Metabolic Mass Balance Model
The design and development of Controlled Ecological Life Support Systems (CELSS) in support of future Lunar and Martian bases requires analytical models for evaluating human and biological...

NASA's Future Plans for Space Astronomy and Astrophysics
This paper presents NASA's plans for future space astronomy and astrophysics through the first decade of the next century. Discussed will be specific missions and mission concepts, as...

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...

Mitigation of Adverse Environmental Effects on Lunar-Based Astronomical Instruments
The galactic cosmic-ray flux incident on the Moon was examined for its potential adverse impact on the performance of the large lunar telescope (LLT) proposed as a part of NASA's Space...

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...

Developing Technologies for Lunar-Based Astronomy
The Moon is probably the best place in the inner solar system to locate a new generation of astronomical observatories. The thrust of space program planning is toward a return to the Moon...

The Lunar Transit Telescope (LTT): An Early Lunar-Based Science and Engineering Mission
The moon is an excellent spacecraft, with mass, rotational, thermal and orbital properties which make its utilization as a base for astronomical observations superbly reasonable. The Lunar...

Lunar Transit Telescope Lander Design
The lunar surface offers a unique platform for telescopes to observe distant planets. The absence of significant atmosphere provides clarity that is of orders of magnitude better when...

Some Considerations for Instrumentation for a Lunar-Based Solar Observatory
Outstanding problems in solar physics, observational trends and directions of instrumental development in solar astronomy are discussed briefly. These lead to the specification of observational...

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...

Design of a Support and Foundation for a Large Lunar Optical Telescope
NASA is considering a large lunar telescope [LLT] and a smaller diameter precursor telescope experiment on the Moon. The preliminary design of the 16-meter optical aperture is being performed...

Mars Basing
Transportation options for getting humans to and from Mars are understood much better than are the Mars basing options themselves. Current crew mission designs do not yet integrate planetary...

Systems Integration of Lunar Campsite Vehicles
This paper describes the configuration design and subsystems integration resolution for lunar Campsite vehicles and the crew vehicles (CVs) which support them. Briefly stated, this concept...

Spaceborne Construction and Operations Planning: Decision Rules for Selecting EVA, Telerobot, and Combined Work-Systems
The development and implementation of Lunar and Mars Missions will require integration of numerous architectures for both on-orbit and planetary surface engineering and construction. These...

A Systems Approach to Water Recycling Research
Because of the cost of Earth resupply, water recycling from wastewater is a critical enabling technology for long duration space missions. The need and the fact that water quality is not...

Towards a Spacefaring Civilization
Three questions are addressed: (1) Is the U.S. a spacefaring nation? (2) Are we a spacefaring civilization? What are the benefits of being one? If we are not, how do we become one? (3)...

Multiple Booster Spaceports
Multiple Booster Spaceports examined launching an entire class of space boosters, both current and future, from a single spaceport. The United States presently launches four distinct classes...

Launching Facility Constraints on the Space Exploration Initiative
The Space Exploration Initiative (SEI) proposes large space programs such as a human mission to Mars and the establishment of a lunar base. These programs will require massive logistical...
