🚀 New publication highlights the complete PAGER space weather forecasting chain 🚀 How do we transform space weather forecasts into actionable spacecraft risk indicators? The newly published major collaborative paper in Advances in Space Research, bringing together the partners of the PAGER project to present an integrated European approach to space weather forecasting and satellite risk assessment. This work demonstrates how we can move from: Solar activity ➡️ Solar wind forecasting ➡️ Radiation belt modelling ➡️ Spacecraft environment prediction ➡️ Engineering risk indicators for satellite operators At Artenum, we are proud to contribute to the final step of this modelling chain. Using the Space-Suite ecosystem, we transform forecasted radiation and plasma environments into physics-based charging risk assessments, enabling engineers and operators to understand what space weather actually means for their spacecraft. 🔹 Our contributions include: ✅ Surface charging risk assessment ✅ Internal charging risk assessment ✅ Coupling of space-weather forecasts with engineering simulation tools ✅ Operational risk indicators for representative spacecraft and orbits Rather than simply forecasting the environment, the objective is to answer a much more practical question: "What will be the impact on my spacecraft?" This system-level approach is becoming increasingly important with the growing number of satellites operating in GEO, MEO and other radiation-intensive environments, where anticipating charging events can contribute to improving mission reliability and supporting operational decision-making. Congratulations to all partners of the PAGER consortium for this excellent collaborative work and to the many co-authors who made this achievement possible.

🚀 EDGE 3.2.0 Released – New parametric multi-point dose analysis 🚀 At Artenum, we are pleased to announce the release of EDGE 3.2.0, the latest version of our ExtendeD GDML Editor, part of the Space-Suite ecosystem. One of the major new capabilities of this release is the “parametric multi-point dose analysis”, helping engineers better understand how radiation dose varies inside sensitive spacecraft components. 🔹 Why does this matter? Radiation dose is rarely uniform within an electronic unit or scientific instrument. Depending on the surrounding geometry and shielding, different locations inside the same component can experience significantly different radiation levels. With EDGE 3.2.0, engineers can now automatically evaluate the radiation dose at multiple locations inside a sensitive component in a single fast workflow. 🔹 The results can be visualized as: ✅ Dose profiles ✅ 2D dose maps providing a much clearer picture of the spatial dose distribution. In the example below, 117 locations were automatically evaluated within the same component, revealing a 50% variation between the lowest and highest predicted dose. 🔹 This new capability helps engineers: ✅ Identify radiation hot spots inside sensitive equipment ✅ Better understand shielding effectiveness ✅ Assess dose gradients within components ✅ Prepare detailed radiation analyses before Monte Carlo simulations 🔹 Beyond this new feature, EDGE provides an integrated environment for: ✅ CAD preparation and geometry investigation ✅ Material assignment ✅ GDML, Gmsh, STEP and MCNP interoperability ✅ Sector Shielding Analysis (SSAM) ✅ Integration with Geant4, SEE-U and SPIS based simulation workflow At Artenum, we develop engineering software that bridges geometry preparation and physics-based simulations, helping engineers design more reliable spacecraft. Interested in EDGE or the Space-Suite ecosystem? We would be happy to discuss how our tools can support your next mission. #EDGE #SpaceSuite #RadiationShielding #SpaceEngineering #GDML #Geant4 #MCNP #Simulation #ScientificComputing #Artenum

🚀 25 Years of Gmsh in space engineering – Our presentation now available 🚀 Last week, Artenum had the pleasure of participating in the Gmsh User Meeting 2026 in Liège. We would like to thank the organizers, the Gmsh developers, and the entire community for the good discussions and for bringing together users from different scientific and engineering domains. During our talk, we shared how Gmsh has been at the heart of our modelling ecosystem for more than 25 years, supporting the development of numerous open-source and industrial tools dedicated to space environment effects. 🔹Some of the topics covered include: ✅ Why high-quality meshing is essential for reliable multi-physics simulations ✅ How Gmsh supports our complete modelling workflow, from CAD preparation to scientific visualization 🔹 Application examples in: ✅ Spacecraft surface charging (SPIS) ✅ Internal charging ✅ Electric propulsion ✅ Radiation transport and shielding ✅ Lunar dust simulations ✅ CAD repair and geometry reconstruction One of the key messages of our talk is that meshing is far more than a pre-processing step. The mesh directly impacts the accuracy, robustness and computational performance of numerical simulations. This is particularly true when modelling complex spacecraft geometries and challenging space environments. For those who could not attend the meeting, we have made our presentation available below. Finally, thank you to Christophe Geuzaine, Jean-François Remacle and everyone contributing to Gmsh. It has become an essential building block for countless scientific applications, including several developed at Artenum. #Gmsh #OpenSource #ScientificComputing #Simulation #Meshing #SpaceEngineering #SpaceSuite #SPIS #Keridwen #Penelope #ComputationalPhysics #Artenum

🚀 New publication – Spacecraft charging in polar Earth orbit 🚀 Why do some satellites suddenly charge to kilovolts while others don’t, under identical space weather conditions? Our latest paper, published in IEEE Xplore Transactions on Plasma Science, investigates this question using the SPIS spacecraft–plasma interaction simulation framework: https://lnkd.in/eA7AuyZK This work, conducted at Artenum in collaboration with European Space Agency - ESA and the U.S. Air Force Research Laboratory, sheds light on the physical mechanisms behind severe spacecraft charging observed in missions such as FREJA and DMSP. 🔹 Key findings ✅ High-energy electron precipitation is the main trigger of severe charging events ✅ Surface material properties (especially Secondary Electron Yield) strongly determine charging severity ✅ Plasma dynamics, ion drift, and spacecraft geometry significantly affect differential charging and discharge risk 🔹 Why it matters With the rapid growth of LEO constellations, understanding and predicting spacecraft charging is becoming critical for mission reliability, especially in polar and high-inclination orbits. Physics-based tools like SPIS (https://www.spis.org/), mainly developed by Artenum and ONERA - The French Aerospace Lab and supported by European Space Agency - ESA, CNES and the SPINE community, enable engineers to move from environmental conditions to actionable design and risk assessment. Many thanks to our collaborators at ESA and AFRL for this publication. #SpacecraftCharging #SpaceWeather #PlasmaPhysics #SPIS #SpaceEngineering #Simulation #IEEE #LEO #SpaceSystems

🚀 From Geometry to Radiation Risk Assessment – Sharing Our RADSHIELD 2026 Presentation 🚀 Last week, Artenum had the pleasure of participating in the European Space Agency - ESA RADSHIELD Workshop at ESTEC, dedicated to one of the key challenges of space engineering: radiation shielding for spacecraft and future exploration missions. Our presentation explored how integrated modelling workflows can help bridge the gap between: ✅ Spacecraft geometry and material definition ✅ Radiation transport simulations ✅ Engineering metrics such as shielding effectiveness, radiation dose and risk assessment ✅ Design trade-offs between protection, performance and mass At Artenum, we believe that efficient radiation analyses require more than standalone tools. They require an integrated modelling workflow that connects CAD models to engineering decisions. During the workshop, we presented how the SpaceSuite ecosystem addresses this challenge by combining: ✅ EDGE – geometry preparation and interoperability (GDML, STEP, MCNP) ✅ SSAM – fast sector shielding analyses and rapid trade studies ✅ MoORa – detailed Monte Carlo particle transport simulations based on European Space Agency - ESA's GRAS/Geant4 We also illustrated these approaches through practical applications, including shielding assessments of CubeSat platforms operating in realistic space radiation environments. A big thank you to European Space Agency - ESA and all participants for the excellent discussions and exchanges throughout the workshop. We are pleased to share our presentation with the community and look forward to continuing discussions on radiation shielding, integrated simulation workflows and space environment effects. #RADSHIELD #ESA #RadiationShielding #SpaceEngineering #Geant4 #GRAS #CubeSat #SpaceSuite #EDGE #MoORa #ScientificComputing #Artenum  

🚀 Radiation Shielding for Space Missions: From CAD Models to Engineering Decisions 🚀 Next week, Artenum will participate in the European Space Agency - ESA RADSHIELD Workshop (https://lnkd.in/enMM2-Zv) at ESTEC, dedicated to one of the key challenges in space engineering: radiation shielding for spacecraft, instruments and future exploration missions. Radiation shielding is often a trade-off between competing objectives: ✅ Protect sensitive electronics and detectors ✅ Minimize mass and system complexity ✅ Maintain mission performance and reliability Making the right decisions requires more than radiation environment data alone. Engineers need modelling tools capable of connecting: ✅ Spacecraft geometry ✅ Material properties ✅ Radiation transport simulations ✅ Mission-specific risk indicators At RADSHIELD, we will present how these capabilities are integrated within the Space-Suite ecosystem through a unified workflow combining: ✅ EDGE for geometry preparation and interoperability (GDML, STEP, MCNP) ✅ SSAM for quick sector shielding analyses ✅ MoORa for detailed Monte-Carlo transport simulations based on European Space Agency - ESA's GRAS / Geant4 Our presentation will illustrate this approach through real applications, including radiation analyses performed for the SPAM instrument of the ESA M-MATISSE mission developed by IRAP - Institut de Recherche en Astrophysique et Planétologie and shielding assessments of CubeSat platforms in realistic space environments. We look forward to discussing with the European radiation-effects community how integrated modelling workflows can help bridge the gap between mission design, radiation analysis and engineering decision-making.

🚀 From Space Weather Forecasts to Operational Charging Risk Assessment 🚀 In our last publications, we discussed an important challenge for the space industry: space environment indicators alone are not enough to understand spacecraft risks. The same electron flux levels can produce very different effects depending on: ✅ Spacecraft geometry ✅ Materials and shielding ✅ Internal design and configuration This is exactly why Artenum developed the Forecast Charging Service: https://lnkd.in/eYD99Thg 🔹 What the service does Our platform transforms: Space-weather forecasts → charging simulations → engineering risk indicators Instead of only monitoring the environment, the service estimates the potential impact on spacecraft systems, including risks for: ✅ Internal charging risks ✅ Surface charging risks 🔹 Why this matters High-energy electron environments in GEO and MEO can evolve rapidly. Operational teams need more than raw flux data: they need actionable information linked to spacecraft behaviour and reliability. 🔹 A physics-based operational workflow The Forecast Charging Service combines: ✅ Space-weather forecasts and radiation models ✅ Physics-based charging simulations ✅ Risk-oriented indicators for spacecraft operations The methodologies behind the platform have been validated through scientific publications and comparisons with in-flight anomaly observations. Moving from “environment monitoring” to “system-aware risk forecasting” is a key step toward more reliable and resilient space missions.

🚀 New Scientific Publication – From Space Environment to System-Level Risks 🚀 We are pleased to contribute to a new scientific publication now available in Advances in Space Research: https://lnkd.in/eqZcUGCF This collaborative work brings together several partners to advance the understanding of how space environment variations translate into real risks for spacecraft systems. Special thanks to GFZ Helmholtz Centre for Geosciences. 🔹 Artenum’s contribution In this study, Artenum contributed to: ✅ Coupling environmental flux forecasts and models with effect-oriented simulation tools ✅ Translating radiation and plasma environments into engineering-relevant risk indicators ✅ Supporting the analysis of system-level impacts 🔹 Why this matters Moving from “environment data” → “physical effects” → “mission risks” is a key challenge for the space industry. This work demonstrates how modelling chains can: ✅ Connect space-weather inputs to actual spacecraft responses ✅ Enable more realistic risk assessments ✅ Support both design and operational decision-making 🔹 From research to operational tools These approaches are directly aligned with what we develop at Artenum through SpaceSuite, where: ✅ Physics-based models are integrated into complete workflows ✅ Forecast data feeds risk assessment tools ✅ Engineering teams can anticipate and mitigate space environment effects This publication is another step towards making space weather actionable for spacecraft systems.

🚀 New Scientific Publication – From Space Environment Indicators to System-Level Risk Forecasting 🚀 We are pleased to share a new scientific publication co-authored by Artenum, GFZ Helmholtz Centre for Geosciences, SES Satellites and Earth, Space, and Planetary Sciences, UCLA now available on IEEE Xplore: https://lnkd.in/efhgj-Sy This work presents the validation of a physics-based modelling chain (PAGER) designed to forecast internal charging risks on spacecraft in GEO. 🔹 Why environment data alone is not enough Space weather indicators such as Kp index or high-energy electron fluxes are essential to describe the environment. However, they are not sufficient to directly identify or predict spacecraft anomalies. Indeed, the impact of the environment strongly depends on: ✅ Spacecraft geometry ✅ Material properties ✅ Shielding and system design As a result, similar environmental conditions can lead to very different system responses. 🔹 From environment to system response The PAGER modelling chain bridges this gap by linking: ✅ Environment (electron fluxes, space weather conditions) ✅ Particle transport and charge deposition ✅ Internal electric field build-up in components 🔹 Validation with real anomalies The study shows a strong correlation between simulated electric field peaks and actual in-flight spacecraft anomalies. This demonstrates that accounting for geometry and material-dependent effects is key to correctly identifying risk conditions. 🔹 An operational capability Because it is validated against real events, this approach can be used in an operational context to: ✅ Detect risk conditions not visible from environment data alone ✅ Provide system-relevant indicators ✅ Support spacecraft operations and anomaly analysis 🔹 From research to service This capability is already available through our operational platform: https://lnkd.in/eYD99Thg Providing space weather-driven charging risk forecasts at system level. Moving from environment monitoring to physics-based, system-aware risk assessment is a key step for improving spacecraft reliability.
