THE CENTER FOR ASTROPHYSICAL SCIENCES (CAS) AT THE JOHNS HOPKINS UNIVERSITY (JHU) PROPOSES TO CONTINUE OUR LONG-STANDING JOHNS HOPKINS UNIVERSITY (JHU) COOPERATIVE AGREEMENT WITH THE NASA GODDARD SPACE FLIGHT CENTER (GSFC). THIS AGREEMENT COVERS RESEARCH IN EXPERIMENTAL OBSERVATIONAL ANALYTIC NUMERICAL AND THEORETICAL SPACE SCIENCE AND ENGINEERING. IT IS RECOGNIZED THAT WORKING TOGETHER SCIENTISTS ENGINEERS AND RESEARCHERS FROM THE JHU AND THE GSFC CAN SHARE EXPERTISE AND RESOURCES TO MAXIMIZE THE RETURN FROM NASA MISSION INVESTMENTS. THE COOPERATIVE AGREEMENT BETWEEN THE JOHNS HOPKINS UNIVERSITY AND THE NASA GODDARD SPACE FLIGHT CENTER HAS RESULTED IN MANY FRUITFUL COLLABORATIONS AND PRODUCTIVE RESEARCH AND HAS ENABLED JHU STUDENTS AND JUNIOR RESEARCHERS TO OBTAIN TRAINING FROM WELL-ESTABLISHED RESEARCHERS IN THE FIELD THUS EXPANDING THE EXPERTISE AT JOHNS HOPKINS UNIVERSITY AND BROADENING EDUCATIONAL OPPORTUNITIES FOR OUR STUDENTS. THESE AGREEMENTS HAVE ENHANCED THE ABILITY OF GODDARD PROFESSIONALS TO COLLABORATE WITH JHU FACULTY INSTRUMENTALISTS AND ENGINEERS RESEARCH SCIENTISTS POST-DOCTORAL FELLOWS GRADUATE STUDENTS AND UNDERGRADUATE STUDENTS. FOR EXAMPLE THESE AGREEMENTS HAVE PROVIDED A MECHANISM FOR JHU-AFFILIATED SCIENTISTS TO WORK AT GSFC AND FOR GSFC SCIENTISTS TO VISIT JHU. THE VISITING PERIODS MAY RANGE FROM HOURS TO DAYS TO MONTHS TO FOSTER MUTUALLY BENEFICIAL INTERACTION AND COLLABORATION. THE PROPOSED COOPERATIVE AGREEMENT FOR RESEARCH IN SPACE SCIENCE (CARS) PLACES NO REQUIREMENTS ON NASA; ALL INTERACTIONS AND RESEARCH ACTIVITIES OCCUR ONLY WITH THE EXPRESS APPROVAL AND CONSENT OF NASA CIVIL SERVANTS. WE PROPOSE TO RENEW THE HIGHLY PRODUCTIVE COOPERATIVE AGREEMENT FOR AN ADDITIONAL FIVE YEARS IN THE FORM OF CARS PHASE IV AS DESCRIBED IN THIS PROPOSAL.
