SpaceX to Lower Orbits of 4,400 Starlink Satellites for Enhanced Space Safety

Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
SpaceX is lowering the orbits of approximately 4,400 Starlink satellites from about 342 miles (550 km) to roughly 298 miles (480 km) over the course of 2026. This mass migration aims to enhance space safety by reducing ballistic decay time during solar minimum periods when atmospheric density decreases. The orbital adjustments will condense Starlink orbits and improve space traffic management as solar activity changes.

· 3 pulledAll Starlink broadband spacecraft currently orbiting 342 miles (550 kilometers) or so above Earth — about 4,400 satellites — will descend to an altitude of roughly 298 miles (480 km) over the course of 2026.
As solar minimum approaches, atmospheric density decreases, which means the ballistic decay time at any given altitude increases — lowering will mean a >80% reduction in ballistic decay time in solar minimum.
Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways.
