Space Safety
Current SOCRATES data indicates a manageable conjunction risk environment for Starlink assets, with two MODERATE-risk events identified among ten total tracked events in early April 2026. The highest-risk conjunction involves STARLINK-6303 and STARLINK-6281 on Apr 8, 2026 at 18:19 UTC, with a maximum collision probability of 17.4% and minimum approach distance of 43 meters—the closest approach of the tracked events. Concurrently, four Starlink satellites are predicted to reenter Earth’s atmosphere between Apr 5-7, 2026, with decay windows ranging from 240 to 1440 minutes, representing routine end-of-life operations rather than anomalous degradation.
