1. The effect of spacecraft charging on low-energy ion measurements around comet 67P/Churyumov-Gerasimenko
Abstract : A spacecraft in space interacts with the surrounding environment and aqcuires an electrostatic potential. Charged particles are constantly bombarding the surface of the spacecraft, and at the same time solar EUV radiation induces photoemission, causing electrons to be emitted from the surface. READ MORE

2. Low-energy ions around comet 67P/Churyumov-Gerasimenko
Abstract : Low-energy ions play important roles in the formation of the plasma environment around a comet. Reliable ways of measuring these ions are therefore of high importance to fully understand the processes and dynamics of this environment. Unfortunately, low-energy ions are infamously difficult to detect. READ MORE

3. Rosetta Observations of Plasma and Dust at Comet 67P
Abstract : In-situ observations of cometary plasma are not made because they are easy. The historic ESA Rosetta mission was launched in 2004 and traversed space for ten years before arriving at comet 67P/Churyumov-Gerasimenko, which it studied in unprecedented detail for two years. READ MORE

4. Diving Deep into Saturn's Equatorial Ionosphere with Cassini : Insights from the Grand Finale
Abstract : In the summer of 2017, the Cassini mission concluded its nearly 13 years orbiting Saturn with a series of daring dives between the rings and the upper reaches of Saturn's atmosphere. This last phase of the mission, called the Grand Finale, revealed a highly variable equatorial ionosphere dominated by a large influx of ring material from Saturn's D ring. READ MORE
