This blog post is based on the papers “Evolution of the ion environment of #Comet_67P/Churyumov-Gerasimenko: Observations between 3.6 and 2.0 AU ” by H. Nilsson et al.; “Rosetta observations of solar wind interaction with the comet 67P/Churyumov-Gerasimenko” by T.W. Broiles et al.; and “Solar Wind Sputtering of Dust on the Surface of 67P/Churyumov-Gerasimenko ” by Peter Wurz et al., which have all been accepted for publication in Astronomy and Astrophysics, and “Dynamical features and spatial structures of the plasma interaction region of 67P/Churyumov–Gerasimenko and the solar wind” by C. Koenders et al, which is published in Planetary and Space #Science. #rosetta is making good progress in one of its key investigations, which concerns the interaction between the comet and the solar wind.

This blog post is based on the papers “Orbital elements of material surrounding #Comet_67P/Churyumov-Gerasimenko,” by B. Davidsson et al, and “Search for #satellites near comet 67P/Churyumov-Gerasimenko using #rosetta/OSIRIS #Images,” by I. Bertini et al, which are both accepted for publication in Astronomy and Astrophysics. Ever since its approach to and arrival at Comet 67P/Churyumov–Gerasimenko, Rosetta has been investigating the nucleus and its environment with a variety of instruments and techniques. One key area is the study of #dust grains and other objects in the vicinity of the comet. Earlier this year, an analysis of measurements from GIADA – Rosetta’s Grain Impact Analyzer and Dust Accumulator – and images from the #osiris camera revealed hundreds of individual grains, either bound to (...)
