Analytical Chemistry in Space presents an analysis of the chemical constitution of space, particularly the particles in the solar wind, of the planetary atmospheres, and the surfaces of the moon and planets. Topics range from space engineering considerations to solar system atmospheres and recovered extraterrestrial materials. Mass spectroscopy in space exploration is also discussed, along with lunar and planetary surface analysis using neutron inelastic scattering. This book is comprised of seven chapters and opens with a discussion on the possibilities for exploration of the solar system by mass spectroscopy, with particular reference to analysis of compositional data on solar system objects such as the Earth and meteorites, asteroids, comets, and interplanetary dust. The reader is then introduced to the project administration, instrument design, and spacecraft integration problems that must be solved to successfully fly a space experiment. The following chapters focus on the atmospheres of the sun and planets; the use of mass spectroscopy in solar system exploration and of neutron inelastic scattering in lunar and planetary surface analysis; and extraterrestrial in situ 14 MeV neutron activation analysis. The final chapter is devoted to the advantages and applications of thermal neutron activation to the analysis of certain samples of geological interest. This monograph will be a useful resource for analytical chemists and space scientists.
