available. Since then, feedback have been collected <strong>and</strong> contributed to improve the code by integration of new models, such<br />
as a multi-grid field description, or technologies, such as a script comm<strong>and</strong> layer. In parallel, this interaction with the user<br />
community have helped to identify key issues that should be taken into account to support a community based development<br />
of the next generation spacecraft-plasma interaction simulation library (SPIS). The current status of PicUp3D is presented <strong>and</strong><br />
analyzed with respect to the initial objectives of the project.<br />

Over the last few decades, significant knowledge has been gained in how to protect spacecraft from charging; however,<br />
the continuing technical advancement in the design <strong>and</strong> build of satellites requires on-going effort in the study of spacecraft<br />
charging. A situation that we have encountered is that not all satellite designers <strong>and</strong> builders are familiar with the problem of<br />
spacecraft charging. The design of a satellite involves many talented people with diverse backgrounds, ranging from<br />
manufacturing <strong>and</strong> assembly to engineering <strong>and</strong> program management. The complex design <strong>and</strong> build of a satellite system<br />
requires people with highly specialized skills such that cross-specialization is often not achievable. As a result, designers <strong>and</strong><br />
builders of satellites are not usually familiar with the problems outside their specialization. This is also true for spacecraft<br />
charging. Not everyone is familiar with the definition of spacecraft charging <strong>and</strong> the damage that spacecraft charging can<br />
cause. Underst<strong>and</strong>ing the problem is an important first step in getting everyone involved in addressing the appropriate<br />
spacecraft charging issues during the satellite design <strong>and</strong> build phases. To address this important first step, an educational<br />
multimedia presentation has been created to inform the general engineering community about the basics of spacecraft<br />
charging. The content of this educational presentation is based on relevant published technical papers. The presentation was<br />
developed using Macromedia Flash. This software produces a more dynamic learning environment than a typical slide show<br />
, resulting in a more effective learning experience. The end result is that the viewer will have learned about the basics of<br />
spacecraft charging. This presentation is available to the public through our website, www.dplscience.com, free of charge.<br />
Viewers are encouraged to pass this presentation to colleagues within their own work environment. This paper describes the<br />
content of the multimedia presentation.<br />

There are continuous needs for engineering organizations to improve their design process. Current state of the art<br />
techniques use computational simulations to predict design performance, <strong>and</strong> optimize it through advanced design methods.<br />
These tools have been used mostly by individual engineers. This paper presents an architecture for achieving results at an<br />
organization level beyond individual level. The next set of gains in process improvement will come from improving the<br />
effective use of computers <strong>and</strong> software within a whole organization, not just for an individual. The architecture takes<br />
advantage of state of the art capabilities to produce a Web based system to carry engineering design into the future. To illustrate<br />
deployment of the architecture, a case study for implementing advanced multidisciplinary design optimization processes such<br />
as Bi-Level Integrated System Synthesis is discussed. Another example for rolling-out a design process for Design for Six<br />
Sigma is also described. Each example explains how an organization can effectively infuse engineering practice with new<br />
design methods <strong>and</strong> retain the knowledge over time.<br />
