Polar, Wind and Geotail's Project overview. In the 1990s, collaborations between NASA, the European Space Agency (ESA), and the Institute of Space and Astronautical Science (ISAS) of Japan resulted in the International Solar-Terrestrial Physics (ISTP) Science Initiative. Polar, Wind and Geotail are a part of this initiative, combining resources and scientific communities to obtain coordinated, simultaneous investigations of the Sun-Earth space environment over an extended period of time.
