Today we are reliant on a growing range of space-based assets. To assess inherent space-related risks it is critical to evaluate existing and planned systems. Here we summarise 2019-2020 findings from a wide range of participants. Our analysis includes: the importance of: persistency, all-weather, night and day capabilities, satellite image resolution, and other technical requirements. Hybrid threats, cyber warfare, GPS ‘spoofing’, jamming, and EMP are part of a new generation of threats becoming relevant with rapid space domain exploitation, in addition to space weather impact .
