Abstract High-energy, long gamma-ray bursts (GRBs) can be generated by the core collapse of massive stars at end their lives. When they happen in close-by universe exceptionally bright, as seen from Earth case recent, giant, long-lasting GRB221009A. GRB221009A was produced a collapsing star with redshift 0.152: this event observed many space experiments, which also detected an extraordinary afterglow. The large fluence prompt emission about 0.013 erg cm −2 illuminated geographical region...
Mercury has a surface-bound exosphere that mediates transport of ion and netural species on the surface within Hermean environment. When precipitating solar wind particles impact planet’s regolith, ions may be neutralised backscattered, form chemical reactions with species, or induce sputtering processes. The SERENA (Search for Exospheric Refilling Emitted Neutral Abundances) instrument onboard BepiColombo aims to study these surface-exosphere-magnetosphere interactions, using...
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 during its first Mercury flyby. Here, we describe the observations of SERENA ion sensors nearby and inside magnetosphere. An intermittent high-energy signal, possibly due to interplanetary magnetic flux rope, been downstream Mercury, together with low energy solar wind. Low ions, satellite outgassing, were detected...
The Na exosphere of Mercury is characterized by the variability emission lines intensity and its distribution in time scales from less than one hour to seasonal variations. While faster variations, accounting for about 10–20% fluctuations are probably linked planetary response solar wind Interplanetary Magnetic Field variability, variations (up 80%) should be explained complex mechanisms involving different surface release processes, loss, source migrations exospheric atoms. Eventually, a...
Earth's atmosphere, whose ionization stability plays a fundamental role for the evolution and endurance of life, is exposed to effect cosmic explosions producing high energy Gamma-ray-bursts. Being able abruptly increase atmospheric ionization, they might deplete stratospheric ozone on global scale. During last decades, an average more than one Gamma-ray-burst per day were recorded. Nevertheless, measurable effects ionosphere rarely observed, in any case its bottom-side (from about 60 km up...
Abstract In this paper we report the detection of five strong gamma-ray bursts (GRBs) by High-Energy Particle Detector (HEPD-01) mounted on board China Seismo-Electromagnetic Satellite, operational since 2018 a Sun-synchronous polar orbit at ∼507 km altitude and 97° inclination. HEPD-01 was designed to detect high-energy electrons in energy range 3–100 MeV, protons 30–300 light nuclei MeV n −1 . Nonetheless, Monte Carlo simulations have shown is sensitive photons 300 keV–50 even if with...
The neutral sensor ELENA (Emitted Low‐Energy Neutral Atoms) for the ESA cornerstone BepiColombo mission to Mercury (in SERENA instrument package) is a new kind of low energetic atoms instrument, mostly devoted sputtering emission from planetary surfaces, E∼20 eV up E∼5 keV, within 1‐D (2°×76°). Time‐of‐Flight (TOF) system, based on oscillating shutter (operated at frequencies 100 kHz) and mechanical gratings: incoming particles directly impinge upon entrance with definite timing (START)...

Surface information derived from exospheric measurements at planetary bodies complements surface mapping provided by dedicated imagers, offering critical insights into release processes, dynamics of various interactions within the environment, erosion, space weathering, and evolution. This study explores a method for deriving elemental composition Mercury's regolith in-situ its neutral exosphere using deep neural networks (DNNs). We present supervised feed-forward DNN architecture—a network...
Modern space missions are becoming increasingly complex: the interconnection of units in a satellite is now network terminals linked together through routers, where devices with different level automation and intelligence share same data-network. The traceability transactions performed mostly at terminal log analysis hence it difficult to verify real time reliability interconnections interchange protocols. To improve ease traffic SpaceWire we implemented low-level link analyzer, specific...
