Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...

Protecting Your Work: Balancing the Competing Interests of Ownership
Your firm has invested days, months—perhaps even years—in its latest project. Your staff have poured their thoughts, ideas, and insights into the creation of a bridge, building, overpass,...

A Stewart Platform Lunar Rover
A lunar version of the Robocrane is being developed at the Robot Systems Division of the National Institute of Standards and Technology (NIST) to address the needs of NASA researchers....

Using a Small Satellite Bus As a Dedicated Platform for On-Orbit CSI Experiments
Control-Structure Integration (CSI) technology will be needed for the success of many future space missions, however, this technology will not be seriously considered for use by program...

Interactions Between the Space Station Freedom Attitude Control System and Space Shuttle Remote Manipulator Controller During On-Orbit Assembly Operations
This paper presents the results of dynamics and control interaction analyses involving the Space Shuttle Orbiter, the Shuttle Remote Manipulator System (SRMS), and the Space Station Freedom...

Microgravity Research in a Space Station Environment
A broad class of scientific experiments have evolved which utilize extreme low acceleration environments. A space station can provide such a `microgravity' environment, in conjunction...

A Comparison of Propulsion Systems for Space Exploration
There are three promising propulsion systems that might be used for space missions: chemical, direct nuclear, and nuclear electric. Selecting the best system for a mission involves comparing...

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...

Logistics Carriers for the First Lunar Outpost
This paper describes that aspect of logistics concerned with the design parameters and operation of hardware that may be used to deliver and protect spares and resupply items for NASA's...

Surface Payload Unloading and Deployment Options for a Lunar Return Mission
While planetary exploration studies have focuses on many areas that are critical to mission success, such as landing space transportation vehicles on other planets, a preferred method...

Lunar ISRU: An Evolutionary Approach
The goal of this paper is to provide the reader with a vision of the individual steps required to bring ISRU from the current technological readiness level of lab experimentation, to large...

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...

Evaluating Lunar Base Conceptual Designs
A large number of competing lunar base conceptual designs have been proposed in recent years. The range of assumptions and technologies used in these designs makes comparison difficult....

Tripod Crane Concept for Lunar Surface Construction
A construction scheme using three integrated cranes is proposed. Mikulas proposed a lunar crane concept which introduces a set of three cables in order to stabilize the payload. This paper...

Phased Assembly of a European Space Station
This paper discusses a phased assembly approach for a proposed European Space Station utilising a series of constructional payloads that are delivered to orbit in an established sequence...

A Novel Aerobrake Design for a Mars Lander
A flexible/inflatable aerobrake is proposed for delivering small payloads to Mars as an alternative to propulsion landing. Some results that demonstrate feasibility are presented....

Back to the Future: A Saturn V-Based Low Earth Orbital Transportation Node
The Space Exploration Initiative requires a heavy-lift launch vehicle to succeed. Reviving the Saturn V represents the best option for regaining heavy-lift. Utilizing the Saturn V's two-stage-to-orbit...

Orbital Construction of a NTR Mars Transfer Vehicle
This paper examines a reference Nuclear Thermal Mars Transfer Vehicle (NTMTV) in terms of on-orbit construction. The identification of subassemblies, payload manifesting, on-orbit connections,...

A Methodology for Development of Spaced-Based Assembly Operations
Designing and constructing a large space-based science facility requires the integration of constraints and design variables with assembly operations. Development of such a facility requires...

ESCAPE: Small Payload Strategies
The Extreme ultraviolet Solar Contained Autonomous Payload Experiment (ESCAPE) is a small payload scheduled to fly on the Space Shuttle in April 1992. This payload has been developed at...
