A SpaceX Starlink satellite is tumbling and falling out of space after partial breakup in orbit

One of SpaceX’s Starlink broadband internet satellites suffered an anomaly in orbit on Wednesday (Dec. 17) and is now plunging toward Earth.

The mishap led to a loss of communication with the Starlink spacecraft, which was orbiting at an altitude of 260 miles (418 kilometers), according to the company.

In addition, “the anomaly led to venting of the propulsion tank, a rapid decay in semi-major axis by about 4 km [2.5 miles], and the release of a small number of trackable low relative velocity objects,” representatives of Starlink, a company that’s owned by SpaceX, said in an X post on Thursday morning (Dec. 18). That description suggests that the Starlink satellite’s propulsion tank may have ruptured or suffered some other type of damage.

SpaceX is working with NASA and the U.S. Space Force to keep tabs on the newly liberated pieces of space debris, the post continued, stressing that there’s not much to worry about.

“The satellite is largely intact, tumbling, and will reenter the Earth’s atmosphere and fully demise within weeks. The satellite’s current trajectory will place it below the @Space_Station, posing no risk to the orbiting lab or its crew,” Starlink representatives wrote.

“As the world’s largest satellite constellation operator, we are deeply committed to space safety,” they added. “We take these events seriously. Our engineers are rapidly working to root cause and mitigate the source of the anomaly and are already in the process of deploying software to our vehicles that increases protections against this type of event.”

The Starlink megaconstellation is by far the largest ever assembled. It currently consists of nearly 9,300 active satellites, meaning that SpaceX operates about 65% of all the functional spacecraft zipping around our planet.

And that number is growing all the time. SpaceX has launched 122 Starlink missions this year alone, sending more than 3,000 of the satellites to low Earth orbit.

Starlink satellites have a design lifetime of about five years, and SpaceX deorbits each one intentionally before it conks out in orbit.

The company has taken other steps to mitigate the space-junk threat posed by the megaconstellation as well. For example, Starlink spacecraft avoid potential collisions autonomously, an ability they put into practice quite often: In the first six months of 2025, Starlink satellites conducted about 145,000 evasive actions — an average of about four per spacecraft per month.

There’s no guarantee that every satellite operator is quite so responsible, however. Last week, for example, a satellite recently deployed by a Chinese rocket gave a Starlink spacecraft a close shave, apparently without providing the proper warning ahead of time.

“As far as we know, no coordination or deconfliction with existing satellites operating in space was performed, resulting in a 200-meter close approach between one of the deployed satellites and STARLINK-6079 (56120) at 560 km altitude. Most of the risk of operating in space comes from the lack of coordination between satellite operators — this needs to change,” Michael Nicolls, vice president of Starlink engineering at SpaceX, said via X on Dec. 12.
