Elon Musk’s satellite network Starlink will undergo a major migration in 2026. The constellation of 4,400 satellites is due to be brought down from their current altitude of 550 km above the Earth to 480 km, freeing up space in a crucial part of Earth’s orbit.
Michael Nicolls, SpaceX’s vice president of Starlink engineering, confirmed the move on 1 January, following news in December of an anomaly that sent a cloud of debris into space and caused Starlink to lose contact with one of its satellites. “The satellite is largely intact, tumbling, and will re-enter the Earth’s atmosphere and fully demise within weeks,” Starlink said in a post on X. The US Space Force and NASA were reported to be helping to monitor the “tens” of pieces of debris.
At the time, the incident was blamed on an internal issue and an explosion rather than a collision. Since then, a statement from Nicolls explains the need for the mass satellite descent: “Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways,” he wrote on X, adding: “the number of debris objects and planned satellite constellations is significantly lower below 500 km, reducing the aggregate likelihood of collision.”
Starlink is beginning a significant reconfiguration of its satellite constellation focused on increasing space safety. We are lowering all @Starlink satellites orbiting at ~550 km to ~480 km (~4400 satellites) over the course of 2026. The shell lowering is being tightly…

The move also comes, as Nicolls laid out, “As solar minimum approaches” in 2030-2032. Solar intensity varies on an 11-year cycle—a phenomenon scientists have been measuring for nearly 300 years. During the solar minimum phase, drag on satellites is reduced, meaning debris lingers in space longer, taking up to four years to descend, and increasing the likelihood of a Kessler Syndrome incident where a collision causes debris that causes a knock-on collision, and so on.
Bringing the satellites down now to a lower level will mean, if there is an incident, any debris should come down faster despite the lack of drag in solar minimum, clearing junk from space more quickly, in a matter of months.

Nonetheless, risks remain. The 2026 migration only concerns half of SpaceX’s almost 9,400 operational satellite craft, and Low Earth Orbit (LEO) is being filled by other players, such as the Chinese, who are planning to put over 10,000 satellites into two configurations. The European Space Agency (ESA) has reported 40,000 objects in Low Earth Orbit (LEO) at below 2,000 km altitude, as well as 1.2 million objects in space that may seem small at down to one centimetre in size but could be “catastrophic” in a collision scenario, the agency says.
Starlink has numerous contracts with airlines such as United, Virgin Atlantic, and Scandinavian (as well as other clients) to provide in-flight Wi-Fi to airline passengers.
