This paper briefly reviews the three basic radiation effect mechanisms, and how they interrupt the functionality of currently available non-volatile memory technologies. This paper also presents a very general overview of the radiation environments expected in future space exploration missions. Unfortunately, these environments will be very harsh, from a radiation standpoint, and thus a significant effort is required to develop non-volatile technologies that will meet future mission requirements.

Redefining the approach and philosophy that operations management uses to define, develop, and implement space missions will be a central element in achieving high efficiency mission operations for the future. The goal of a cost effective space operations program cannot be realized if the attitudes and methodologies we currently employ to plan, develop, and manage space missions do not change. A management philosophy that is in synch with the environment in terms of budget, technology, and science objectives must be developed. Changing our basic perception of mission operations will require a shift in the way we view the mission. This requires a transition from current practices of viewing the mission as a unique end product, to a 'mission development concept' built on the visualization of the end-to-end mission. To achieve this change we must define realistic mission success criteria and develop pragmatic approaches to achieve our goals. Custom mission development for all but the largest and most unique programs is not practical in the current budget environment, and we simply do not have the resources to implement all of our planned science programs. We need to shift our management focus to allow us the opportunity make use of methodologies and approaches which are based on common building blocks that can be utilized in the space, ground, and mission unique segments of all missions.

The military has been executing its detection and monitoring mission in the waron drugs for over a year and pressures continue to mount for an expanded military role. This paper reviews the genesis of the current mission and analyzes the measures of effectiveness used in attempting to measure its success. The scope of this analysis focuses on the development of appropriate measures of effectiveness using NWP 11's technique of mission analysis. To be of use, the Measures of effectiveness applied by the military must focus on the specific detection and monitoring mission assigned vice the larger mission of drug interdiction as a whole.

Of late, the international defence community has become very interested in thepotential of Non-Lethal Weapons (NLW). This report deals with the possible contribution of NLW in reaching the operational goals of the Dutch armed land forces. After a first characterization of NLW, a selection is made of the most promising categories of missions and NLW concepts. By analyzing two specific scenarios, the potential of using NLW is illustrated. This analysis is performed using a simplified Quality Function Deployment method. NLW are characterized by the proportionality, reversibility and limited duration of the weapon effects. The most fruitful areas for the use of NLW are considered to be peace support and constrained combat operations, where they augment the existing weapons arsenal. NLW are more task-oriented than lethal weapons. During the study, the need for developing an objective assessment method to evaluate the effectiveness of NLW in general, became evident.

The concept of a quantitative figure-of-merit (FOM) to evaluate different and competing options for space missions is further developed. Over six hundred individual factors are considered. These range from mission orbital mechanics to in-situ resource utilization (ISRU/ISMU) plants. The program utilizes a commercial software package for synthesis and visual display; the details are completely developed in-house. Historical FOM's are derived for successful space missions such as the Surveyor, Voyager, Apollo, etc. A cost FOM is also mentioned. The bulk of this work is devoted to one specific example of Mars Sample Return (MSR). The program is flexible enough to accommodate a variety of evolving technologies. Initial results show that the FOM for sample return is a function of the mass returned to LEO, and that missions utilizing ISRU/ISMU are far more cost effective than those that rely on all earth-transported resources.

Introduction of a new popular magazine on the DI mission, the first West German Space mission. The DI project office publishes the magazine. The German sponsored astronauts are to study the gravitational effects of reduced gravity on the human generated processes of the environment. Other areas of concern are boundary surface and transport phenomena, physical chemisty and process engineering, metals and composite materials, and single crystals.

The methods and techniques for experiment development and integration that evolved during the Skylab Program are described to facilitate transferring this experience to experimenters in future manned space programs. Management responsibilities and the sequential process of experiment evolution from initial concept through definition, development, integration, operation and postflight analysis are outlined in the main text and amplified, as appropriate, in appendixes. Emphasis is placed on specific lessons learned on Skylab that are worthy of consideration by future programs. (Author)
