"...The possible payload of science instruments under consideration includes radar to penetrate the frozen crust and determine the thickness of the ice shell, an infrared spectrometer to investigate the composition of Europa's surface materials, a topographic camera for high-resolution imaging of surface features, and an ion and neutral mass spectrometer to analyze the moon's trace atmosphere during flybys...The nominal Europa Clipper mission would perform 45 flybys of Europa at altitudes varying from 1700 miles to 16 miles (2700 kilometers to 25 kilometers)..."
"...NASA's Jet Propulsion Laboratory in Pasadena, California, has chosen proposals from 10 universities to study CubeSat concepts that could enhance a Europa mission concept currently under study by NASA. The CubeSat concepts will be incorporated into a JPL study describing how small probes could be carried as auxiliary payloads. The CubeSats would then be released in the Jovian system to make measurements and enhance our understanding of Jupiter's moon Europa...The conceptual Europa mission, called Europa Clipper, would conduct detailed reconnaissance of the icy moon and investigate whether it could harbor conditions suitable for life...The universities' Europa science objectives for their CubeSats would include reconnaissance for future landing sites, gravity fields, magnetic fields, atmospheric and plume science, and radiation measurements..."
