ARCA Dynamics: Mapping the Cosmos to Prevent Catastrophic Space Collisions
Episode 65
Wednesday, 19 November, 2025

Space is becoming dangerously crowded. With Goldman Sachs predicting 70,000 low Earth orbit satellites could launch in just the next five years, the risk of catastrophic collisions is escalating rapidly. Unlike cars or planes, satellites have no drivers on board to react in real-time, making precise orbital tracking absolutely essential. Enter ARCA Dynamics, who provide crucial space-based surveillance of orbiting objects.Discover how ARCA Dynamics uses satellites equipped with advanced cameras to observe other satellites and debris from space, providing crucial "state vectors". These state vectors are mathematical snapshots that pinpoint exactly where objects are and how fast they're moving in space. Unlike ground-based observations that can only track satellites when they pass directly overhead, ARCA's space-based approach offers continuous monitoring with multiple observation opportunities. This helps operators prevent collisions, reduce unnecessary fuel-burning maneuvers, and keep vital services online.We traveled to ARCA Dynamics' headquarters in Rome, Italy, where co-founder Marco Moriani and his team showed us how they are revolutionizing how we monitor space. They also told us about their groundbreaking plans to integrate AI directly into satellites in the future, eliminating transmission delays and dramatically increasing detection capabilities.
