Elon Musk’s Starlink is set to lower the altitude of about 4,400 of its satellites from 550 km to 480 km in 2026, a key step in a broader reconfiguration aimed at improving space safety. The plan was announced by Michael Nicholls, Vice President of Starlink Engineering at SpaceX, in a recent post. Starlink, the world’s largest satellite constellation, provides broadband internet across multiple regions, including parts of Africa. In Nigeria, it is the second‑largest internet service provider, serving more than 66,500 customers as of Q2 2025, according to the Nigerian Communications Commission.
The altitude reduction is intended to condense Starlink’s orbital shells, shorten deorbit times and lower collision risks as the solar minimum approaches. During solar minimum, atmospheric density decreases, causing satellites to remain in orbit longer. By operating at a lower altitude, Starlink aims to mitigate these long‑term risks and enhance overall safety. The company will begin moving all satellites currently at roughly 550 km down to about 480 km throughout 2026. This shift is expected to cut ballistic decay time by more than 80 % during solar minimum, allowing satellites that might otherwise take four years or more to deorbit to re‑enter the atmosphere within a few months.
A lower orbital altitude also reduces the probability of collisions, as fewer debris objects and planned constellations exist below 500 km. Starlink’s safety measures are part of a larger initiative to promote the long‑term sustainability of low‑Earth orbit, addressing global concerns about space debris and collision hazards. By proactively lowering its satellites and coordinating with regulators and other operators, Starlink positions itself as a safety‑conscious participant in an increasingly crowded orbital environment.
As the constellation expands its presence in Africa—highlighted by a recent agreement with Airtel Africa to deploy direct‑to‑cell services—Starlink’s commitment to space safety is likely to have a positive impact on the continent’s growing connectivity landscape.
