The Virtual Mission: A Step-Wise Approach to Large Space Missions
The new Virtual Mission concept will provide NASA's Science Program with a powerful new, 'go-as-you-pay,' flexible, and resilient way of accomplishing its science observing program. The...

Space-Based Assembly Sequence Formulation for Evaluation of Large Orbital Assemblies
The challenges associated with constructing interplanetary spacecraft and space platforms in low earth orbit are such that it is imperative that comprehensive, preliminary process planning...

Advanced Construction Management for Lunar Base Construction?Surface Operation Planner
The unprecedented task of constructing a lunar base could easily overwhelm any existing terrestrial construction management system. Couple this with the overall need for lunar surface...

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...

An Operational Evaluation Process for Long-Duration Mission Habitats in Space
In preparation for long-duration manned spaceflight into the 21st Century, the ergonomical and psychological aspects of space habitat architectures are being investigated in Europe. Used...

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...

Mars Via the Moon?A Robust Lunar Resources-Based Architecture
A space operations architecture is outlined that uses lunar materials to cost-effectively support Lunar and Mars exploration and operations. This architecture uses a chemically powered...

Characterization of Emplacement Strategies for Lunar and Mars Missions
In planning missions to the Moon and Mars, a significant activity will be the delivery of the crew and necessary equipment to the planet surface to enable the mission objectives. Because...

A Facility for Training Space Station Astronauts
The Space Station Training Facility (SSTF) will be the primary facility for training the Space Station Freedom astronauts and the Space Station Control Center ground support personnel....

EVA Operational Guidelines and Considerations for Use During the Space Station Freedom Design Review Process
The Space Station Freedom Program (SSFP) has started to conduct many design reviews (DR's) of its elements, systems, and subsystems. These varied systems cross work packages (WP's), international...

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...

Extraction of Potable Water from Urine for Space Applications
A regenerative technology capable of managing water and wastewater on-board long-term manned space platforms is essential if the Bush Administration's Space Exploration Initiative (SEI)...

Space Station & Lunar/Mars Life Support Research
The first part of this paper will report on the tests now being conducted by the Environmental Control and Life Suport Systems (ECLSS) at Marshall Space Flight Center. The findings of...

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...

Utilization of On-Site Resources for Regenerative Life Support Systems at a Lunar Outpost
Regenerative Life Support Systems (RLSS) will be required to regenerate air, water, and wastes, and to produce food for human consumption during long-duration stays on the Moon. It may...

Lunar Base Pressure, O₂ Fraction, and ExtraHabitat Activity Suit Design
A major dilemma exists in determining optimum habitat and ExtraHabitat Activity (EHA) suit pressures for future space missions, balancing human safety requirements and the case of EHA...

Medical Care on the Moon
Eventually, people will return to the Moon to stay for prolonged periods of time. When they do, they will be exposed to a wide range of threats to their health including, decompression...

Artificial Gravity Augmentation on the Moon and Mars
Extended visits to the moon and Mars will require a base on the surface. Exploration of small planetary neighbors will depend upon the development of a life support system that prevents...

Regenerative Life Support Technology Challenges for the Space Exploration Initiative
Regenerative life support systems have been identified as one of the critical enabling technologies for future human exploration of space. This discipline encompasses processes and subsystems...
