SPACE NEWS: SpaceX Announces Move of Thousands of Starlink Satellites to Lower Orbit

SpaceX Engineers Plan Orbital Shift for 4,400 Starlink Satellites

BREVARD COUNTY • KENNEDY SPACE CENTER, FLORIDA – SpaceX plans to reposition roughly 4,400 of its Starlink satellites into a lower Earth orbit this year, a move the company says will improve space safety and reduce operational risks as orbital traffic continues to increase.

The announcement was made on Friday by Michael Nicholls, SpaceX’s vice president of Starlink engineering, who said the orbital adjustment is designed to give the company greater control over its satellites while lowering the chances of long-term debris in space.

Starlink currently operates the world’s largest satellite constellation, accounting for more than 9,000 satellites in orbit, according to the company. Nicholls said only two of those satellites are not functioning.

Lowering the satellites’ operating altitude places them below 500 kilometers above Earth, an orbital region that Nicholls said has fewer debris objects and fewer planned satellite constellations than higher orbits.

Operating closer to Earth also allows failed satellites to reenter the atmosphere more quickly, reducing the risk they could remain in orbit for years as uncontrolled hazards.

“As the orbital environment becomes more congested, rapid and reliable removal of non-functioning satellites is essential,” Nicholls said in his post on X. By moving satellites to a lower orbit, Starlink can ensure that any spacecraft that fails will naturally deorbit faster due to atmospheric drag.

Nicholls also highlighted the role of solar activity in satellite operations. During periods of high solar activity, the Sun heats Earth’s upper atmosphere, causing it to expand and increase drag on satellites, which can shorten their orbital lifespan.

Conversely, during periods of low solar activity—such as the expected solar minimum after 2030—the atmosphere becomes thinner, allowing satellites to stay in orbit longer. Operating at a lower altitude helps counter those effects by ensuring satellites do not linger in orbit indefinitely if problems arise.

The announcement comes just days after Starlink disclosed it had lost contact with one of its satellites.

According to a company statement posted Thursday, an anomaly occurred on Dec. 17 involving satellite 35956 at an altitude of about 418 kilometers, resulting in a loss of communications.

The satellite remains largely intact but is tumbling and is expected to reenter Earth’s atmosphere within weeks. SpaceX said the satellite poses no risk to the International Space Station or its crew and that the company is coordinating with NASA to monitor the situation.

“As the world’s largest satellite constellation operator, we are deeply committed to space safety,” the company said in its statement. “We take these events seriously.”

Starlink’s rapid expansion over the past five years has transformed it into a major global internet provider, particularly in rural and remote regions underserved by traditional broadband infrastructure.

According to SpaceX’s 2024 year-end report, Starlink has connected more than 4.6 million users worldwide and made internet access available to more than 2.8 billion people across dozens of countries.

The growing footprint of the Starlink network has also drawn interest from the U.S. military.

This week, Air Force Special Operations Command published a request for information exploring potential integration of Starlink and its military-focused variant, Starshield, into aircraft platforms such as AC-130 Ghostrider gunships and heavy-lift cargo planes.

As commercial and government activity in Earth’s orbit accelerates, SpaceX says the planned orbital shift reflects a broader effort to balance rapid growth with long-term sustainability in space.

By lowering thousands of satellites, the company aims to reduce collision risks, improve system reliability, and set a precedent for responsible satellite operations in an increasingly crowded orbital environment.
