CAPE CANAVERAL, Florida, January 1, 2026 – SpaceX’s Starlink division plans to reduce the orbital altitude of about 4,400 satellites from approximately 550 kilometers to 480 kilometers during 2026, a change intended to minimize collision risks and speed deorbiting in the increasingly crowded low Earth orbit environment.
Michael Nicolls, vice president of Starlink engineering, explained the rationale in a statement. “Lowering the satellites results in condensing Starlink orbits and will increase space safety in several ways,” he said. Fewer debris objects and planned constellations exist below 500 kilometers, lowering overall collision probability.
The adjustment shortens ballistic lifetime—the time a failed satellite remains in orbit—by more than 80% during the upcoming solar minimum, dropping it from over four years to months.
This reduces exposure to uncoordinated maneuvers or launches by other operators. Starlink maintains high reliability, with only two non-operational satellites among more than 9,000 active ones.
The plan follows a December incident where one satellite malfunctioned, producing minor debris, and reports of close approaches with foreign launches. SpaceX will coordinate with U.S. Space Command and regulators to manage the descent safely.
Starlink, providing broadband to millions worldwide, continues expansion while addressing sustainability. Lower altitudes may slightly improve user latency.
The move reflects proactive steps amid growing orbital congestion from mega-constellations. SpaceX’s actions could set precedents as competitors launch similar networks.
