Microgravity

Microgravity

Introduction

Space flight is important for rnany reasons. Space flight carries scientific instruments and human researchers high above the ground, permitting us to see Earth as a planet and to study the complex interactions of atmosphere, oceans, land, energy, and living things. Space flight lifts scientific instruments above the filtering effects of the atmosphere, making the entire electromagnetic spectrum available and allowing us to see more clearly the distant planets, stars, and galaxies. Space flight permits us to travel directly to other worlds to see them close up and sample their compositions. Finally, space flight allows scientists to investigate the fundamental states of matter—solids, liquids, and gases—and the forces that affect them in a microgravity environment.

The study of the states of matter and their interactions in microgravity is an exciting opportunity to expand the frontiers of science. Areas of invest’gation include biotechnology, combustion scie,lce, fluid physics, fundamental physics, materials science, and ways in which these areas of research can be used to advance efforts to explore the Moon and Mars.

Microgravity is the subject of this teacher’s guide. This publication identifies the underlying mathematics, physics, and technology principles that apply to microgravity. Supplementary information is included in other NASA educational products.
