AI Challenge for Satellite Tracking and Orbit Resilience Modeling (STORM‐AI): Data Set, Design, and Results

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Precise thermospheric density forecasting is critical for mitigating satellite drag in Low Earth Orbit (LEO), but traditional empirical models such as MSIS and JB2008 can fail during geomagnetic storms. To evaluate whether AI can better capture this transient behavior, the 2025 MIT ARCLab Prize for AI Innovation in Space asked participants to ...

Forecasting Local Geomagnetic Disturbances Using Machine Learning: A Multi‐Station Approach

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Geomagnetic indices such as SYM‐H capture global disturbances but fail to resolve regional impacts critical for infrastructure resilience. We present a machine learning model to forecast the Local Disturbance Index (LDi), a validated regional geomagnetic index.

Supporting Informed Shutter Operations for SMILE's SXI Using Ensemble Classifiers for Soft Proton High Flux Period Predictions

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Satellite X‐ray imagers are highly vulnerable to contamination by soft protons (∼100 keV), which can trigger spurious charge‐coupled device events and force interruptions in observations. For XMM‐Newton, such contamination reduced usable science time by ∼40%.
