LatHyS global hybrid simulation of the BepiColombo second Venus flyby
André, N.; Fedorov, A.; Sauvaud, J. -A. +23 more
Plasma and magnetic field observations by BepiColombo during its 2nd Venus flyby in August 10, 2021 have been examined and compared with the newly developed global hybrid simulation LatHyS for the Venusian environment. The LatHyS-Venus simulation was first validated by a comparison with Venus Express observations obtained during average solar wind…
Calibration of ISA accelerometer sensing axes for the BepiColombo mission
Lucente, Marco; Lefevre, Carlo; Fiorenza, Emiliano +3 more
ISA is a three-axis accelerometer embarked on-board BepiColombo, a joint ESA/JAXA space mission launched on the 19th of October 2018 at 22.45 (local time) and devoted to put two spacecraft (MPO and MMO) around Mercury (2025), for a deeper investigation of the planet and its environment. ISA aims at measuring, directly and not by modelli…
Localization of cosmic gamma-ray bursts in interplanetary space with MGNS/BepiColombo and HEND/Mars Odyssey experiments
Golovin, D. V.; Kozyrev, A. S.; Litvak, M. L. +3 more
This paper describes the methods and results for the localization by triangulation of cosmic gamma-ray bursts (GRBs) independently observed by two space experiments: the Mercury Gamma-ray and Neutron Spectrometer (MGNS) and the High Energy Neutron Detector (HEND). MGNS is onboard the MPO/BepiColombo mission and on a stage of cruise to Mercury wher…
Cross-comparison of global simulation models applied to Mercury's dayside magnetosphere
André, N.; Budnik, E.; Génot, V. +14 more
We present the first comparison of multiple global simulations of the solar wind interaction with Mercury's dayside magnetosphere, conducted in the framework of the international collaborative project SHOTS - Studies on Hermean magnetosphere Oriented Theories and Simulations. Two 3D magnetohydrodynamic and two 3D hybrid simulation codes are used t…
Orbital evolution of the BepiColombo Mercury Planetary Orbiter (MPO) in the gravity field of Mercury
Oberst, Jürgen; Hussmann, Hauke; Stark, Alexander +2 more
We assessed the impact of the uncertainties in the gravity field harmonic coefficients of Mercury on the orbital evolution of the Mercury Planetary Orbiter (MPO), part of the European-Japanese BepiColombo mission. We used in our simulations the most recent estimation of the gravity field model of Mercury determined from radio tracking data of the …
Comprehensive in-orbit performance evaluation of the BepiColombo Laser Altimeter (BELA)
Thomas, Nicolas; Hussmann, Hauke; Pommerol, Antoine +7 more
The BepiColombo Laser Altimeter (BELA) is on its way to Mercury on board the Mercury Planetary Orbiter (MPO), one of the two spacecraft of the BepiColombo mission. It will arrive at Mercury in December 2025 and start measurements of Mercury's surface and environment. The goal of this study is to analyze the performance of BELA by using a comprehen…
The performance of the BepiColombo Laser Altimeter (BELA) prior launch and prospects for Mercury orbit operations
Oberst, J.; Stark, A.; Steinbrügge, G. +2 more
We explore the perspectives of the BepiColombo Laser Altimeter (BELA) onboard ESA / JAXA's Mercury mission BepiColombo and present an updated semi-analytical instrument performance model, in which we estimate signal-to-noise ratio, single shot probability of false detection, range errors and the accuracy of pulse width reconstruction. The model is…
