This review presents our understanding of cometary dust at the end of 2017. For decades,
insight about the dust ejected by nuclei of comets had stemmed from remote observations …

The international Rosetta mission was launched in 2004 and consists of the orbiter
spacecraft Rosetta and the lander Philae. The aim of the mission is to map the comet …

The habitability of the surface of any planet is determined by a complex evolution of its
interior, surface, and atmosphere. The electromagnetic and particle radiation of stars drive …

Coupling between the lower and upper atmosphere, combined with loss of gas from the
upper atmosphere to space, likely contributed to the thin, cold, dry atmosphere of modern …

Context. The Rosetta magnetometer RPC-MAG has been exploring the plasma environment
of comet 67P/Churyumov-Gerasimenko since August 2014. The first months were …

We propose to identify the main sources of ionization of the plasma in the coma of comet
67P/Churyumov-Gerasimenko at different locations in the coma and to quantify their relative …

The upper atmospheres of unmagnetized solar system bodies interact more directly with
their local plasma environment than their counterparts on magnetized bodies such as Earth …

Context. The Rosetta spacecraft is escorting comet 67P/Churyumov-Gerasimenko from a
heliocentric distance of> 3.6 AU, where the comet activity was low, until perihelion at 1.24 …

Rosetta has followed comet 67P from low activity at more than 3.6 au heliocentric distance to
high activity at perihelion (1.24 au) and then out again. We provide a general overview of the …

One of the primary objectives of the Rosetta Plasma Consortium, a suite of five plasma
instruments on-board the Rosetta spacecraft, is to observe the formation and evolution of …
