SpaceX will gradually lower 4,400 Starlink satellites this year to improve space safety.
SpaceX announced it will lower approximately 4,400 Starlink satellites from 550 km to 480 km above Earth throughout 2026 to reduce the risk of collisions in low Earth orbit. The move will also shorten the satellites’ end-of-life decay time by more than 80 percent.
The decision follows a December incident in which one Starlink satellite created minor debris and briefly cut communications with another spacecraft. Michael Nicholls, SpaceX vice-president of engineering, said the adjustment will also mitigate risks from uncoordinated maneuvers and launches by other operators.
Estimates from the European Space Agency indicate over 40,000 objects orbit below 2,000 km, with more than 9,300 owned by SpaceX. Objects over 1 cm in size, over 1.2 million pose potential collision hazards.
Professor Hugh Lewis of the University of Birmingham said SpaceX carried out 144,404 collision avoidance maneuvers between December 2024 and May 2025, a 200 percent increase from the previous period.
Nicholls emphasized the satellite adjustments are part of SpaceX’s ongoing efforts to make orbital operations safer as congestion in low Earth orbit increases.
