The primary launch for a coming Chinese language web megaconstellation turned out to be fairly messy.
On Tuesday morning (Aug. 6), a Chinese language Lengthy March 6A rocket launched the primary 18 satellites for the Qianfan (“Thousand Sails”) broadband community, which is able to finally host as much as 14,000 spacecraft.
The rocket efficiently delivered the satellites to low Earth orbit (LEO), at an altitude of about 500 miles (800 kilometers). However its higher stage broke aside shortly thereafter, producing a cloud of particles that is now racing round our planet, in line with United States Area Command (USSPACECOM).
“USSPACECOM can affirm the breakup of a Lengthy March 6A rocket launched on Aug. 6, 2024, leading to over 300 items of trackable particles in low Earth orbit,” the group mentioned in a statement today (Aug. 8). “USSPACECOM has noticed no fast threats and continues to conduct routine conjunction assessments to assist the protection and sustainability of the area area.”
“Trackable particles” is usually any object that is not less than 4 inches (10 centimeters) in diameter. The newly spawned particles cloud likely additionally comprises many shards which can be too small to watch.

This was a worrisome begin for the Thousand Sails constellation, in line with Slingshot Aerospace, a California-based firm devoted to advancing area area consciousness and sustainability.
“If even a fraction of the launches required to discipline this Chinese language megaconstellation generate as a lot particles as this primary launch, the consequence could be an untenable addition to the area particles inhabitants in LEO,” Audrey Schaffer, vp of technique and coverage at Slingshot, mentioned in an emailed assertion.
“Occasions like this spotlight the significance of adherence to current area particles mitigation tips to scale back the creation of latest area particles and underscore the necessity for sturdy area area consciousness capabilities to quickly detect, observe and catalog newly launched area objects to allow them to be screened for potential conjunctions,” she added.
This is not the primary time a Lengthy March 6A higher stage — which weighs about 12,800 kilos (5,800 kilograms) with out propellant — has spawned a particles cloud in orbit, as Slingshot famous. One of many rocket our bodies broke aside on Nov. 12, 2022, shortly after deploying the Yunhai-3 climate satellite tv for pc, in line with NASA particles consultants.
That occasion created 533 items of trackable particles by January 2023, in line with the March 2023 issue of NASA’s “Orbital Particles Quarterly Information.”
Earth orbit is getting an increasing number of crowded, with each energetic satellites and items of particles. According to the European Space Agency, there are about 10,000 operational spacecraft zooming round our planet in the intervening time (most of them SpaceX Starlink web satellites), roughly 40,500 items of particles not less than 4 inches (10 cm) large and 130 million shards not less than 1 millimeter in diameter.
