Eos mission design utilizing the Space Station platforms

NASA is formulating a program that will encompass many scientific disciplines and involve a large share of the international scientific community in the study of planet earth. The mission is planned for the 1990s and will involve at least four spacecraft: two provided by the NASA and one each provided by European Space Agency (ESA) and Japan. The NASA platforms will utilize elements of the Space Station Freedom program to provide the basic spacecraft engineering subsystems. These subsystems are intended to serve as the basis for future earth orbiting United States spacecraft.
