Discovery of heavy negative ions in Titan's ionosphere
[1] Titan's ionosphere contains a rich positive ion population including organic molecules. Here, using CAPS electron spectrometer data from sixteen Titan encounters, we reveal the existence ofExpand

The Process of Tholin Formation in Titan's Upper Atmosphere
Titan's lower atmosphere has long been known to harbor organic aerosols (tholins) presumed to have been formed from simple molecules, such as methane and nitrogen (CH4 and N2). Up to now, it has beenExpand

Modelling the surface and subsurface Martian radiation environment: implications for astrobiology
The damaging effect of ionising radiation on cellular structure is one of the prime limiting factors on the survival of life in potential astrobiological habitats. Here we model the propagation ofExpand

Warping of Saturn's magnetospheric and magnetotail current sheets
[1] The magnetotails of Jupiter and Earth are known to be hinged so that their orientation is controlled by the magnetic field of the planet at small distances and asymptotically approach theExpand

JUpiter ICy moons Explorer (JUICE): An ESA mission to orbit Ganymede and to characterise the Jupiter system
Past exploration of Jupiter's diverse satellite system has forever changed our understanding of the unique environments to be found around gas giants, both in our solar system and beyond. TheExpand

RPC-MAG The Fluxgate Magnetometer in the ROSETTA Plasma Consortium
The fluxgate magnetometer experiment onboard the ROSETTA spacecraft aims to measure the magnetic field in the interaction region of the solar wind plasma with comet 67P/Churyumov-Gerasimenko. ItExpand

Properties of local plasma injections in Saturn's magnetosphere
[1] Electron and ion drift dispersion events are often observed by the Cassini Plasma Spectrometer (CAPS) in the inner magnetosphere of Saturn (5 to 10 RS). These events appear to result fromExpand
