Under Bridge and Rossi, the MIT space plasma group included Frank Scherb, Edwin Lyon, Alan Lazarus, Alberto Bonnetti, Alberto Egidi, John Belcher and Constance Dilworth, who was Occhialini's wife. Its Faraday cups have collected data on plasma throughout the Solar System: near Earth on OGO-1, OGO 3 and IMP 8, in interplanetary space on WIND, and in the Heliosphere and Heliosheath on Voyager 1 and Voyager 2.
