SpaceX—SpaceX announced plan to lower 4,400 Starlink satellites from 550km to 480km to reduce debris persistence
On January 1, 2026, SpaceX VP of Starlink Engineering Michael Nicolls announced plans to lower approximately 4,400 satellites from 550km to 480km altitude throughout 2026. The lower orbit reduces ballistic decay time by over 80% during solar minimum, meaning derelict satellites deorbit far faster. This represented a proactive effort to address orbital debris concerns given Starlink's dominance (two-thirds of all operational satellites).
