Physics of Space Plasmas was one of the first textbooks published in the area of space plasma physics and included up-to-date observations from space available at that time. It has been used in the United States and abroad by many universities as a text in introductory space plasma physics courses. A considerable number of new space plasma observations have been made since publication of the first edition. These more recent observations have revealed new and exciting information about space plasma and will enhance the quality of the overarching discussion and analyses of space plasma physics. Citing results from several NASA and ESA space missions, the completely revised Second Edition now expands the interpretation using kinetic physics to explain the kinetic features in the plasma data. Parks also includes a clear and simple discussion of how electromagnetic fields behave in rotating frames. This revision retains the thoughtful examples and problems of the First Edition and includes new ones to complement the new material and changes in the Second Edition.
