Direct evidence of substorm-related impulsive injections of electrons at Mercury
Barabash, Stas; Futaana, Yoshifumi; Persson, Moa +22 more
Mercury's magnetosphere is known to involve fundamental processes releasing particles and energy like at Earth due to the solar wind interaction. The resulting cycle is however much faster and involves acceleration, transport, loss, and recycling of plasma. Direct experimental evidence for the roles of electrons during this cycle is however missin…
The second Venus flyby of BepiColombo mission reveals stable atmosphere over decades
Haus, Rainer; Arnold, Gabriele; Hiesinger, Harald +4 more
Studies of the Venusian mesosphere provide important information about the current state of the entire Venusian atmosphere. This includes information about the dense cloud structure, its vertical thermal profile, temperature fields, and the resulting dynamical and meteorological processes that contribute to a deeper understanding of the climatolog…
Inner southern magnetosphere observation of Mercury via SERENA ion sensors in BepiColombo mission
Kallio, E.; Barabash, S.; Holmström, M. +89 more
Mercury's southern inner magnetosphere is an unexplored region as it was not observed by earlier space missions. In October 2021, BepiColombo mission has passed through this region during its first Mercury flyby. Here, we describe the observations of SERENA ion sensors nearby and inside Mercury's magnetosphere. An intermittent high-energy signal, …
BepiColombo mission confirms stagnation region of Venus and reveals its large extent
André, N.; Fedorov, A.; Barabash, S. +42 more
The second Venus flyby of the BepiColombo mission offer a unique opportunity to make a complete tour of one of the few gas-dynamics dominated interaction regions between the supersonic solar wind and a Solar System object. The spacecraft pass through the full Venusian magnetosheath following the plasma streamlines, and cross the subsolar stagnatio…
