China’s Long March 6A rocket, which successfully launched 18 Qianfan satellites on August 6, broke apart soon after, generating nearly 300 pieces of debris in low Earth orbit. This event, one of the largest rocket breakups in history, has sparked fresh concerns over space debris and China’s approach to space junk management.
The Long March 6A rocket was part of an ambitious plan to establish the Qianfan (“Thousand Sails”) broadband network, China’s answer to Elon Musk’s Starlink. The rocket was launched from the Taiyuan Satellite Launch Centre in Shanxi Province, North China. Despite the successful deployment of the satellites, the rocket’s disintegration has overshadowed the achievement.
According to LeoLabs, a U.S.-based space-tracking firm, the breakup could result in at least 700 fragments, floating about 500 miles above Earth. These fragments are expected to remain in orbit for decades, posing long-term risks to other satellites and space activities. Although Starlink has stated that the debris does not present an immediate threat to its fleet, the incident highlights the growing issue of space junk.
This incident has intensified global scrutiny of China’s space practices. Darren McKnight, a senior technical fellow at LeoLabs, expressed concern over China’s recent track record, calling the Long March 6A breakup a potential “wake-up call” for Beijing to engage in international discussions on space debris mitigation.
Quentin Parker, director of the Laboratory for Space Research at the University of Hong Kong, likened the current state of space governance to the “Wild West,” with little enforcement of sustainable practices. The need for better international regulation is becoming increasingly urgent as the number of rocket launches continues to rise.
China’s Foreign Ministry spokesman, Lin Jian, responded by emphasizing that China “attaches great importance to space debris mitigation” and has been actively working to fulfill international obligations. However, the details of China’s measures following the recent incident remain unclear.
This is not the first time China has faced criticism for its handling of space debris. In 2022, a Chinese rocket stage made an uncontrolled re-entry into the Sulu Sea, drawing criticism from NASA for inadequate data sharing. The Long March 6A missions, in particular, have become notorious for contributing significantly to the space debris problem, raising concerns about the safety and sustainability of low Earth orbit environments.
As global space activities increase, the issue of space junk is becoming more pressing, with calls for stricter international cooperation and enforcement to prevent future incidents.
