On the Mesoscale Structure of Coronal Mass Ejections at Mercury's Orbit: BepiColombo and Parker Solar Probe Observations
Dresing, Nina; Nieves-Chinchilla, Teresa; Weiss, Andreas J. +27 more
On 2022 February 15, an impressive filament eruption was observed off the solar eastern limb from three remote-sensing viewpoints, namely, Earth, STEREO-A, and Solar Orbiter. In addition to representing the most-distant observed filament at extreme ultraviolet wavelengths—captured by Solar Orbiter's field of view extending to above 6 R ⊙
Multispacecraft Observations of a Widespread Solar Energetic Particle Event on 2022 February 15–16
Holmström, M.; Lario, D.; Palmerio, E. +37 more
On 2022 February 15–16, multiple spacecraft measured one of the most intense solar energetic particle (SEP) events observed so far in Solar Cycle 25. This study provides an overview of interesting observations made by multiple spacecraft during this event. Parker Solar Probe (PSP) and BepiColombo were close to each other at 0.34–0.37 au (a radial …
The solar cycle 25 multi-spacecraft solar energetic particle event catalog of the SERPENTINE project
Hayes, L. A.; Vainio, R.; Mitchell, J. G. +26 more
Context. The solar energetic particle analysis platform for the inner heliosphere (SERPENTINE) project, funded through the H2020-SPACE-2020 call of the European Union's Horizon 2020 framework program, employs measurements of the new inner heliospheric spacecraft fleet to address several outstanding questions on the origin of solar energetic partic…
Spacecraft Outgassing Observed by the BepiColombo Ion Spectrometers
André, N.; Cornet, T.; Orsini, S. +19 more
During the first flyby of the BepiColombo composite spacecraft at Mercury in October 2021 ion spectrometers observed two intense spectral lines with energies between 10 and 70 eV. The spectral lines persisted also at larger distances from Mercury and were observed again at lower intensity during cruise phase in March 2022 and at the second and thi…
Pseudo-Drag-Free System Simulation for Bepicolombo Radio Science Using Accelerometer Data
Cappuccio, Paolo; di Stefano, Ivan; Iess, Luciano +6 more
The Mercury Orbiter Radio Science Experiment onboard the European Space Agency/Japan Aerospace Exploration Agency (JAXA) BepiColombo mission aims at determining the gravity field and the rotational state of the planet to provide insight into its internal structure and at performing tests of general relativity. The experiment will rely on accurate …
Determining the Influence of the IMF and Planetary Magnetic Field Models on Mercury's Magnetosphere Along Spacecraft Trajectories of MESSENGER, BepiColombo and MPO
Heyner, Daniel; Exner, Willi; Griton, Léa. S.
Mercury's planetary magnetic field models (PMFMs) agree on a majorly dipolar field structure with a northward shift of the magnetic equator. However, due to the northerly biased orbit coverage of past spacecraft missions and different data analyzing methods, the available PMFMs differ in the determined multipole magnitudes for the dipole, quadrupo…
Structure and dynamics of the Hermean magnetosphere revealed by electron observations from the Mercury electron analyzer after the first three Mercury flybys of BepiColombo
André, N.; Fedorov, A.; Sauvaud, J. -A. +16 more
Context. The Mercury electron analyzer (MEA) obtained new electron observations during the first three Mercury flybys by BepiColombo on October 1, 2021 (MFB1), June 23 , 2022 (MFB2), and June 19, 2023 (MFB3). BepiColombo entered the dusk side magnetotail from the flank magnetosheath in the northern hemisphere, crossed the Mercury solar orbital equ…
Understanding the Dust Environment at Mercury: From Surface to Exosphere
Krüger, Harald; Kobayashi, Masanori; Murakami, Go +13 more
We provide an overview of our understanding of the dust environment at Mercury and the role that dust plays in shaping the planet's surface and exosphere. Our understanding of the role that dust impacts play in the generation of Mercury's atmosphere has evolved considerably with continued analysis of results from the MErcury Surface, Space ENviron…
BepiColombo observations of cold oxygen and carbon ions in the flank of the induced magnetosphere of Venus
André, N.; Fedorov, A.; Krupp, N. +25 more
On 10 August 2021, the Mercury-bound BepiColombo spacecraft performed its second fly-by of Venus and provided a short-lived observation of its induced magnetosphere. Here we report results recorded by the Mass Spectrum Analyzer on board Mio, which reveal the presence of cold O+ and C+ with an average total flux of ~4 ± 1 × 10…
Solar wind entry into Mercury's magnetosphere: Simulation results for the second swingby of BepiColombo
Narita, Y.; Motschmann, U.; Exner, W. +7 more
Context. We use a global 3D hybrid plasma model to investigate the interaction between Mercury's magnetosphere and the solar wind for the second BepiColombo swingby, evaluate magnetospheric regions, and study the typical energy profile of protons.
Aims: The objective of this study is to gain a better understanding of solar wind entry and anal…
