And Another LM-6A Pollutes LEO with Debris

7 Aug: Shortly after delivering its payload to an ~700-800km orbit, the LM-6A upper-stage appears to have generated a large debris field ( LEOlabs estimates of 700-900+ pieces ).

7 Aug: Shortly after delivering its payload to an ~700-800km orbit, the LM-6A upper-stage appears to have generated a large debris field (LEOlabs estimates of 700-900+ pieces). The event creates a hazard for other spacecraft operating at similar or lower altitudes for decades. This is the same altitude region that China previously polluted with its 2007 kinetic Anti-Satellite (ASAT) test which generated 3,432 pieces of trackable debris, over 80% of which remain on orbit. This is not the first LM-6A upper-stage debris generating event. To date 4 of 7 LM-6A upper-stages have generated debris.

– The US Space Force released a statement confirming the breakup: “The breakup likely occurred Aug. 7, at 1548 UTC. The tracked pieces are being incorporated into routine conjunction assessment to support spaceflight safety. There are currently no threats to human spaceflight. Analysis is ongoing.”

– The LM-6A is one of China’s newest rockets and can deliver up to 4.5 metric tons (9,900 pounds) into a 700-kilometer (435-mile) Sun-synchronous orbit.

– The LM-6A has had a history of orbital mishaps resulting in unnecessary debris. In addition to the 6 Aug 2024 launch there have been the following incidents:

– The space catalog also lists 2 pieces of debris with launch of the Yaogan-40 triplets in 2023 (2023-139).

– The LM-6A upper-stage is proving to be a menace for all space faring nations (China included).

– China released a statement on 14 Aug 2024, acknowledging the debris event and “to take space debris mitigation measures.” Talk’s cheap.
