The Microgravity Program has become part of the newly established Office of Biological and Physical Research (OBPR), NASA's fifth Enterprise. Meanwhile, we commenced the long-awaited and exciting era of conducting Microgravity Fluid Physics experiments on the International Space Station (1SS). We successfully completed the Physics of Colloids in Space (PCS) experiment on 1SS and launched the Investigating Structure of Paramagnetic Aggregates of Colloidal Emulsions (lnSPACE) experiment that will be conducted later this year. The excitement of utilizing 1SS was tempered, however, by its cost problems that negatively impacted the research budget available for developing flight experiment facilities and hardware. As a result, the Microgravity Fluid Physics discipline took a significant budget reduction that caused deferral/discontinuation of a number of flight investigations that had successfully completed their peer-reviews and received their endorsement. The budget supporting the principal investigators was also negatively impacted, though to a smaller extent. On the positive side, the Fluids Integrated Rack (FIR) that supports much of fluid physics experiments survived these budget reductions. Also the subsequent support of the research community through letters to Congress and to NASA clearly showed how the research community values the Microgravity Fluid Physics and Transport Phenomena Program. In March, NASA Administrator Sean O'Keefe created the Research Maximization And Prioritization (REMAP) Task Force to perform an independent review and assessment of research priorities for the entire scientific, technological, and commercial portfolio of the Agency's Office of Biological and Physical Research (OBPR) and to provide recommendations on how the office can achieve its research goals. The panel report was released on July 10, 2002. The recommendations of this panel placed almost all of the research content of the Microgravity Fluid Physics Program in Priority 1 or 2 putting the program in an advantageous position as NASA begins to implement the recommendations of the panel. The program currently has a total of 106 ground-based and 16 candidate flight principal investigators. A look at the collection of abstracts in this document clearly shows both the high quality and the breadth of the ongoing research program. One can easily notice many established world-class scientists as well as investigators who are early in their career poised to achieve that stature. We hope that many of the participants in this conference will perceive microgravity fluid physics as an exciting and rewarding area of research and choose to participate in the NASA Research Announcement released in December 2001. Proposals submitted to the fluid physics research area are due December 2, 2002. More information can be found at the following Web site: http://research.hq.nasa.gov/code_u/nra/current/N RA-01-OBPR-08/index.html The content of the Microgravity Fluid Physics and Transport Phenomena Program is well aligned with OBPR's mission of "conducting basic and applied research to support human exploration of space and to take advantage of the space environment as a laboratory for scientific, technological, and commercial research." The fluid physics discipline has a major role in the Physical Sciences Division's goal of developing a rigorous, cross-disciplinary scientific capability, bridging physical sciences and biology to address NASA's human and robotic space exploration goals. We have implemented a number of changes in the format of this conference based on the inputs received from the participants. We have expanded plenary sessions to include all presentations, eliminated parallel sessions and expanded the exposition session with poster presentations. We hope that this will allow the participants to get a better picture of the overall program through the plenary presentations and promote focused discussion/dialogue through poster presentations. The Discipline Working Group has provided the much-needed guidance in planning the content and the format of this conference. As in the past, we elected to go with a virtual proceedings of the presentation charts that will be available on the World Wide Web at http://www.ncmr.org/events/fluids2002.html. In this regard we acknowledge the support of our principal investigators who have provided us timely inputs of their charts and abstracts and accommodated our format requirements. This cooperation was critical in implementing this and is very much appreciated.
