A Starlink satellite appears to have exploded and is now spiraling toward Earth

Caused by an internal energy event, not a collision

What just happened? SpaceX confirmed that one of its Starlink satellites has malfunctioned and is now descending toward Earth following what the company described as an anomaly. Elon Musk's firm reported a sudden loss of communications, a drop in altitude, "venting of the propulsion tank," and the "release of a small number of trackable low relative velocity objects" – signs that suggest a possible internal explosion aboard the spacecraft.

According to SpaceX, the satellite will reenter Earth's atmosphere within weeks, and the event poses no danger to the crew of the International Space Station.

The private space-monitoring firm Leo Labs said that its radar network detected "tens of objects" in the vicinity of the affected spacecraft, known as Starlink 35956. The company described the likely cause as an internal energy source, indicating that a collision with another object did not trigger the anomaly.

SpaceX has not published further details about whether the satellite's systems had shown any prior irregularities before the loss of control.

The failure comes roughly a week after SpaceX disclosed that one of its Starlink units narrowly avoided a collision with a Chinese satellite. The incident has renewed attention on the growing congestion in low Earth orbit, where a dense population of spacecraft increases the complexity of orbital management and raises long-term risks.

The disabled Starlink satellite was orbiting at an altitude of 418 kilometers, roughly 260 miles above Earth. That region, classified as low Earth orbit, or LEO, has become one of the busiest environments in space. More than 24,000 objects, including active satellites, defunct spacecraft, and debris, are currently being tracked in this zone.

Industry projections suggest the number could climb to as many as 70,000 satellites by the end of the decade, mainly fueled by large-scale internet constellations like SpaceX's Starlink and other broadband networks under development by companies and government programs in the United States, China, and Europe.

As commercial operators continue to expand broadband services from orbit, astronomers and safety analysts have warned that such dense traffic increases the likelihood of collisions. A single uncontrolled impact could generate a chain reaction of debris events, potentially rendering key orbital bands unusable for years.

For now, SpaceX says the remains of Starlink 35956 will safely disintegrate during atmospheric reentry. But the episode has sharpened the discussion about how fragile the balance of low Earth orbit has become.
