Gravity affects a wide variety of scientific areas, some of which have profound implications for space exploration. Scientific disciplines that are affected include fundamental physics, fluid mechanics and transport phenomena, materials science, biological sciences, and combustion.

In the current context, however, microgravity describes the acceleration conditions attending free-fall, that is, the acceleration sensed within an inertial reference frame that is at rest with respect to the local environment but accelerating toward the center of the Earth. Such conditions occur for limited periods in drop towers and in aircraft executing parabolic orbits.

In summary, microgravity research involves strong elements of traditional laboratory science, in contrast with the observational science that constitutes most of the NASA space science program. Experiments often involve controlled model systems and exacting parameter settings.

1 provided guidance during the program's early years, whereas Space Science in the Twenty-First Century: Imperatives for the Decades 1995 to 20152 attempted to identify future research opportunities. More recently, the 1992 report Toward a Microgravity Research Strategy3 began to lay a foundation for a more mature research program, and the current report is a continuation of that effort.

The remainder of Part I of this report discusses current research opportunities and presents the major conclusions and recommendations of the report. Specific conclusions and recommendations for each of the five disciplines of microgravity research are discussed first and are followed by general recommendations and conclusions that prioritize research issues and provide some general guidance for administrative policy and procedures.
