China’s Shenzhou-20 spacecraft took a success from a work of house particles floating via orbit, inflicting Chinese language officers to lengthen the spacecraft’s go back from its Tiangong house station in early November 2025.
Along with stranding the 3 Chinese language astronauts – known as taikonauts – who have been set to go back to Earth, this incident highlights the expanding dangers posed to China and the wider global group via the rising quantity of house particles.
I learn about China’s house program. My analysis means that nationwide delight performs crucial function in China’s rising house ambitions. As China continues to spend money on dear house features, it’s going to additionally most probably turn into an increasing number of delicate to shedding them. The upward thrust in house particles might create incentives for Chinese language officers to cooperate with the US on measures that cut back the danger of collisions.
Area particles – a rising factor
Area particles is growing rising issues for house operations. It comprises any synthetic items in orbit now not working as satellites or spacecraft. It levels in measurement from a fleck of paint to huge rocket our bodies more or less the dimensions of a college bus.
In essentially the most frequently used orbit – low Earth orbit – this particles can transfer at speeds of more or less 18,000 mph, nearly seven occasions the rate of a bullet. At such excessive speeds, even tiny items of house particles will also be extremely damaging, to the purpose that this particles would possibly proceed to multiply till in the future it makes positive crucial orbits unusable. When house particles collides with different items and fragments, they may be able to destroy into smaller items, producing much more particles.
It’s relatively ironic that China’s spacecraft took a success from house junk. The rustic is chargeable for growing the vast majority of house particles. In 2007, China blew up a defunct Fengyun-1c climate satellite tv for pc to check an anti-satellite weapon. It generated essentially the most house particles in historical past – over 3,000 items are nonetheless orbiting nowadays.
This quick clip presentations the rise in house particles in orbit round Earth.
On a number of events, the Global Area Station has needed to maneuver to narrowly steer clear of being struck via particles from this take a look at, together with as just lately as 2021.
Anti-satellite guns
Why would China, or every other nation, wish to increase an anti-satellite weapon? Satellites supply important advantages to militaries. They lend a hand with reconnaissance and intelligence, permit for the correct concentrated on and steering of long-range munitions, make stronger verbal exchange over massive distances and provide climate knowledge, to call only a few makes use of.
Those benefits have been showcased all through the primary Gulf Battle, steadily known as the “first space war.” America used house applied sciences to temporarily and decisively defeat the Iraqi army inside of weeks, and with some distance fewer casualties than anticipated. The Gulf Battle had a profound have an effect on on Chinese language army considering, with analysts within the Other people’s Liberation Military spotting the significance of house applied sciences in fashionable battle.
While the US has been and stays extremely depending on house features, China has traditionally been much less depending on them. Which means that China has historically had some distance much less to lose from putting satellites in orbit and relatively extra to realize from disabling an adversary’s satellites.
Because the Nineties, China has invested in applied sciences that may jam, disable or outright spoil any other nation’s satellites. This effort has been pushed via a want to counter what it sees as a key vulnerability of the U.S. army – its heavy reliance on house features.
But a lot has modified since China’s first anti-satellite take a look at in 2007.
China has regularly narrowed the distance with the US in house features and is now some of the robust spacefaring countries on Earth. Because of this, China now has extra at stake if it have been to lose get right of entry to to house.
Area particles is changing into a significant danger to Chinese language pursuits in house. In 2022, for instance, experiences emerged that particles from Russia’s 2021 ASAT take a look at got here dangerously as regards to a Chinese language satellite tv for pc. In a similar way, in 2021 China filed a declare on the United International locations that China’s Tiangong house station needed to carry out avoidance maneuvers because of “close encounters” with Starlink satellites. And now, in November 2025, China’s Shenzhou-20 spacecraft has in reality been struck via house particles.
Spotting the issue
It’s too early to gauge how severely Chinese language officers view the specter of house particles. Then again, the high-profile nature of this contemporary incident might alert China’s public and officers to the dangers posed via house particles.
China’s house station, its astronauts and its satellites are essential to the Chinese language Communist Birthday party. If house particles completely destroyed portions or all of China’s house station, and even killed a Chinese language astronaut, it will most probably result in important public outcry.
China’s house station is a mission over 3 many years within the making and is the crown jewel of its house program. The Tiangong is about to turn into the one house station in orbit if the US proceeds with its plans to deorbit the ISS in 2030.

Simply as an proprietor of a pricey Lamborghini might turn into an increasing number of fearful about bad highway stipulations that can injury their prized ownership, Chinese language officers might turn into apprehensive about China’s skill to function its house station must house junk proceed to mess low Earth orbit.
Even though house particles does now not injury China’s house station, it nonetheless poses a possibility to Chinese language satellites. And coffee Earth orbit is prone to turn into simplest extra crowded, as SpaceX has introduced plans so as to add as much as 40,000 Starlink satellites in orbit, and China plans so as to add tens of 1000’s extra satellites in low Earth orbit via its Guowang and Qianfan satellite tv for pc megaconstellations.
China’s rising vulnerability to house particles creates a space of mutual worry the place the US and China might be able to paintings in combination to steer clear of long run injuries.

Chance-reduction measures may come with the 2 nations notifying every different about possible collisions. China and the US may additionally open discussions round learn how to safely function satellites or take away them from orbit once they’re not helpful.
It continues to be observed what courses Chinese language decision-makers draw from this contemporary episode. However the issue of house particles isn’t going away.
