Space science, or the space sciences, are fields of science that are concerned with the study or utilization of outer space. There are several major fields of space science including astronomy, exobiology, space transport, and space exploration and colonization. In addition, space sciences impact or are related to many other fields, from the biology of organisms in space environments to the geology of other bodies and planets (astrogeology), as well as nuclear physics in interstellar space and inside stars. This bibliography provides information sources which provide guidance to students, parents and teachers throughout the process of planning, developing, implementing and competing in science fair activities related to space science. Sources range in suitability from elementary to secondary school levels. This guide updates "Library of Congress Science Tracer Bullet" 92-7, "Space Science Projects" [ED361190]. Sources in other areas of science and on science fairs themselves are listed in "Science Fair Projects" (TB 01-6), "Environmental Science Projects" (TB 97-6), and "Science Projects in Biology" (TB 93-7). Not intended to be a comprehensive bibliography, this guide is designed--as the name tracer bullet implies--to put the reader "on target."
