William H. Smyth 1941-2011
William H. Smyth passed away on Friday Sept. 30, 2011 after a long illness. Bill was a leader in planetary exospheres and conducted pioneering research on the exospheres of Io, Europa, Mercury, the moon, comets, and the Saturnian H cloud, especially in complex orbital environments. His expertise on Io’s neutral clouds and the plasma torus were second to none.
