Case for · why it matters

Space Force officials worry about Chinese and Russian spacecraft that fly close to U.S. and European satellites. Startups such as Fortastra and True Anomaly are building maneuverable spacecraft that can approach, inspect and, if needed, act against threats to other satellites.

Case against · the skeptic’s view

Close-in, uncooperative operations have little flight heritage: Fortastra's founder says there is not much data to support them, and True Anomaly's Jackal demonstrations have been self-funded test flights. Funded programs of record for active satellite defense remain limited.
