China Space Debris: 3 of 4 Worst Events This Century 2026

China is responsible for three of the four worst space debris episodes of the 21st century, and a recent event shows the problem is not improving. On June 9, the Chinese rocket Zhuque-2E successfully released two satellites into low Earth orbit. Its upper stage had completed its mission. But unlike SpaceX, China does not reuse its rockets, and like any space company—private or public—it has an obligation to ensure its discarded rockets do not pose a risk to the space neighborhood or to Earth itself.

Unfortunately, the Asian country is not very efficient at preventing this. So it is not entirely surprising that the upper stage of Zhuque-2E ended up exploding, violently ejecting more than 100 pieces at a dangerous distance from the International Space Station and many of the Starlink satellites.

What Happened with the Zhuque-2E Upper Stage?

The US Space Force, tasked with inspecting space for potential hazardous activity, raised the alarm about this event. Few details were given beyond the fact that the responsible party was the Zhuque-2E rocket, with an upper stage 8 meters long and 3.35 meters in diameter. However, Darren McKnight, senior technical researcher at orbital intelligence firm LeoLabs, ventured to calculate in statements to Ars Technica that the explosion possibly released between 100 and 150 pieces.

The debris was ejected at a dangerous distance from the International Space Station and a large portion of Starlink satellites. This near-miss highlights the growing risks of space debris in low Earth orbit, where congestion is increasing.

Why This Matters for Space Safety

Space debris poses a significant threat to operational satellites and human spaceflight. Each piece can travel at speeds up to 17,500 mph, enough to cause catastrophic damage upon impact. The Zhuque-2E incident adds to a worrying trend of Chinese rockets contributing to orbital debris.

China's non-reusable rocket approach means more upper stages are left in orbit, increasing the chance of explosions and collisions. This not only endangers the ISS and Starlink but also other satellites and future missions.

• China is responsible for three of the four worst space debris events this century.
• The Zhuque-2E upper stage exploded on June 9, creating 100-150 pieces of debris.
• Debris passed dangerously close to the ISS and Starlink satellites.
• China's non-reusable rockets contribute to the growing space debris problem.
• International space agencies are monitoring the situation closely.

Comparing Space Debris Events

To understand the scale of the problem, here is a comparison of major space debris events in the 21st century, including the recent Zhuque-2E incident.

This table shows that while the Zhuque-2E event produced fewer pieces than the 2007 and 2009 events, it still contributes to the hazardous debris environment. The 2007 Chinese anti-satellite test remains the worst single debris event in history.

Who Is Affected by the Zhuque-2E Debris?

The immediate concern is the International Space Station, which hosts astronauts and must perform avoidance maneuvers when debris threatens. Starlink satellites, operated by SpaceX, are also at risk due to their large number in low Earth orbit.

Other satellite operators, including those providing GPS, weather, and communication services, could be affected. The debris cloud will disperse over time, but each piece remains a potential hazard for years.

What to Watch Next

International space agencies and tracking companies will continue to monitor the debris from the Zhuque-2E explosion. China's space program faces increasing scrutiny over its debris mitigation practices. The incident may prompt calls for stronger international regulations on rocket stage disposal.

As space becomes more congested, responsible behavior from all spacefaring nations is essential. The Zhuque-2E event serves as a reminder that space debris is not just a theoretical problem but a real and present danger.
