SpaceX is making a major change to its Starlink satellite constellation in an effort to further improve safety in low Earth orbit. The company says it will begin lowering thousands of Starlink satellites to a lower operational altitude this year, a move aimed at reducing debris risk and speeding up deorbit timelines if a satellite ever fails.
The update was shared by SpaceX’s Vice President of Starlink Engineering, Michael Nicolls, who said the company is “beginning a significant reconfiguration of its satellite constellation focused on increasing space safety.” According to Nicolls, SpaceX plans to lower all Starlink satellites currently orbiting at roughly 550 kilometers (340 miles) above the planet down to about 480 kilometers (300 miles) over the course of 2026. That affects around 4,400 satellites.
“We are lowering all Starlink satellites orbiting at ~550 km to ~480 km (~4400 satellites) over the course of 2026,” Nicolls said, adding that “the shell lowering is being tightly coordinated with other operators, regulators, and USSPACECOM.”
Lowering the orbital shell brings several safety benefits. “As solar minimum approaches, atmospheric density decreases which means the ballistic decay time at any given altitude increases,” Nicolls explained. By flying lower, Starlink can dramatically shorten how long an inactive satellite remains in orbit. “Lowering will mean a >80% reduction in ballistic decay time in solar minimum, or 4+ years reduced to a few months,” he said.
Operating below 500 kilometers (310 miles) also reduces congestion. Nicolls noted that “the number of debris objects and planned satellite constellations is significantly lower below 500 km, reducing the aggregate likelihood of collision.”
The move follows a recent Starlink satellite anomaly in December, when a satellite malfunctioned, decayed from orbit, and began an uncontrolled descent to Earth. It is expected to burn up entirely in the atmosphere during reentry. While SpaceX says Starlink has “extremely high reliability, with only 2 dead satellites in its fleet of over 9000 operational satellites,” Nicolls emphasized that faster deorbiting is critical. “If a satellite does fail [in] orbit, we want it to deorbit as quickly as possible,” he said.
The announcement comes as Starlink continues to scale rapidly. The constellation now has more than 9,000 active satellites and is expected to cross 10,000 in the coming weeks. Starlink also doubled its global user base to 9.2 million in 2025, expanded to 35 new markets, and rolled out Direct to Cell service to millions of users worldwide.
Looking ahead, 2026 is shaping up to be another pivotal year for Starlink, with major network upgrades and next-generation Starlink V3 satellites expected to launch aboard SpaceX’s Starship, paving the way for even higher speeds and gigabit connectivity.
