Yunhai-1 03’s predecessor, Yunhai-1 02, launched in September 2019 and was apparently hit by space debris in March 2021. The cause of the collision was established in a small fragment of the body of the Russian Zenit-2 rocket.

Yonghai 1-02 appears to still be able to adjust its orbit despite the crash, which occurred at an altitude of 485 miles (780 kilometers), space debris expert Jonathan McDowell said in August 2021. (will open in a new tab).

McDowell also said (will open in a new tab) this incident was the first confirmed major orbital collision since February 2009. Then the Russian military spacecraft Kosmos-2251 collided with an active communications satellite known as Iridium-33, resulting in 1,800 traceable debris. (will open in a new tab) by next October.
