THIS PROPOSAL IS TO REQUEST THE 4-6TH YEAR FUNDING FROM THE 2016 NASA HELIOPHYSICS U.S. PARTICIPATING INVESTIGATOR (USPI) PROJECT TITLED U.S. PARTICIPATION IN THE SMILE MISSION. THE PROPOSAL FIRST INTRODUCES SOLAR WIND MAGNETOSPHERE IONOSPHERE LINK EXPLORER (SMILE) AND THE ORIGINAL NASA H-USPI PROPOSAL ACTIVITIES. THEN IT SUMMARIZES PREVIOUS YEAR ACTIVITIES AND OUTLINES NEXT 3-YEAR RESEARCH PLAN. THE SUGGESTED ACTIVITIES WILL SUPPORT THE SUCCESSFUL PREPARATION OPERATION AND SCIENCE CLOSURE OF THE SMILE MISSION. THE KEY OBSTACLE TO EFFECTIVE COMMUNICATION OF RESEARCH IN SOLAR-TERRESTRIAL PHYSICS IS THAT IT INVOLVES THE STUDY OF MANY PROCESSES THAT ARE COMPLICATED AND ESSENTIALLY INVISIBLE TO THE NAKED EYE. SMILE HAS THE POTENTIAL TO REVOLUTIONIZE THE GENERAL UNDERSTANDING OF THIS AREA OF SCIENCE BY PROVIDING X-RAY IMAGES OF THE MAGNETOSPHERIC BUBBLE SHIELDING OUR EARTH FROM INCLEMENT SOLAR WIND CONDITIONS. A COMPREHENSIVE COMMUNICATION AND OUTREACH PROGRAM IS BEING PREPARED TO TAKE FULL ADVANTAGE OF THESE NOVEL DATA.
