SpaceX calls for better orbital data sharing to prevent collisions

SpaceX has called for satellite operators to share information about their spacecraft positions to reduce collision risks in orbit.

SpaceX has called for satellite operators to share information about the positions and trajectories of their spacecraft to prevent collisions in orbit. Michael Nicolls, SpaceX's vice president for Starlink and president of Elon Musk's artificial intelligence company xAI, made the call at the International Astronautical Congress in Turkey. He cited recent near-misses involving Starlink that resulted in conjunctions of tens to hundreds of metres, distances he described as too close for comfort.

Starlink currently operates more than 11,000 satellites, representing about two-thirds of all active spacecraft in low-Earth orbit. SpaceX has plans to launch a million additional satellites for a constellation called Starmind to deploy AI computing in orbit. Amazon is preparing to launch thousands of satellites to compete with Starlink, and two Chinese megaconstellations are in full-scale deployment.

The proliferation of satellites raises collision risks that could trigger a self-perpetuating cycle of debris generation. While the risk of any single collision on a given day is low, Nicolls warned that the law of large numbers means that if a collision can happen, it eventually will. Improved data-sharing among all operators is needed to mitigate this risk as more megaconstellations populate low-Earth orbit.
