Studying Jupiter's magnetospheric response to Io's volcanic activity

IO''S VOLCANIC ACTIVITY HELPS IT TO MAINTAIN A TENUOUS ATMOSPHERE. IN A CLASSIC \''CHICKEN AND EGG\'' PROBLEM, IONS IN IO''S ATMOSPHERE ARE PICKED UP BY JUPITER''S RAPIDLY ROTATING MAGNETIC FIELD AND, UPON SUBSEQUENT ROTATIONS, OVERTAKE IO WITH A RELATIVE VELO

COMETS ARE SOME OF THE LEAST EVOLVED MEMBERS OF OUR SOLAR SYSTEM. STUDY OF THEIR COMPOSITION AND STRUCTURE IS THEREFORE FOUNDATIONAL TO OUR UNDERSTANDING OF THE FORMATION AND EVOLUTION OF THE SOLAR SYSTEM. REMOTE SENSING STUDIES ARE CURRENTLY THE PRIMARY

GALEX OBSERVATIONS OF COMET 8P/TUTTLE COMETS ARE PRIMORDIAL OBJECTS LEFT OVER FROM THE FORMATION OF THE SOLAR SYSTEM. THEIR STUDY IS THEREFORE DIRECTLY RELEVANT TO NASA STRATEGIC SUB-GOAL 3C: ''ADVANCE SCIENTIFIC KNOWLEDGE OF THE ORIGIN AND HISTORY OF
