The European Space Agency (ESA) has issued a Call for Proposals for the First Planning Cycle of the New Cosmic Vision 2015-2025 (http://sci.esa.int/cv2015). It is anticipated that some U.S. investigators may wish to participate in the flight programs that will result from the advanced studies being solicited by the Call, and NASA is interested in the possibility of supporting U.S. investigator participation in future flight projects.
