AB: We report here results of the first operation in space of the Ion and Electron Sensor (IES) on board the European Space Agency's Rosetta spacecraft, on its way to rendezvous with comet Churyumov-Gerasimenko in 2014. The instrument became fully operational on the night of 8/9 September 2004, at which time Rosetta was about 1.04 AU from the Sun and 30 deg ahead of Earth's orbital motion. IES is comprised of 2 toroidal top-hat electrostatic analyzers, one each for electrons and ions, providing a 360 deg view in azimuth onto the 2 microchannel plate detectors. A set of deflection plates provides a +/- 45 deg view in elevation. Results of observations of solar wind plasma and comparison with observations by other near-Earth spacecraft will be discussed.
