China anger after space station forced to move to avoid Elon Musk Starlink satellites

China said its space station deployed prevention collision avoidance control measures in July and October and called on the US to ‘bear responsibility’

Beijing has called on the UN to remind the US to abide by the treaty regulating outer space after space satellites launched by tech tycoon Elon Musk’s aerospace company SpaceX almost collided with its space station twice in the past year.

China said its space station deployed prevention collision avoidance control measures in July and October to avoid colliding with Starlink satellites in a recent report submitted by Beijing to the UN’s Committee on the Peaceful Uses of Outer Space earlier this month.

“China wishes to request the secretary general of the United Nations to circulate the above-mentioned information to all states parties to the Outer Space Treaty,” the report submitted by its permanent mission in Vienna read.

It added that state parties must “bear international responsibility” for national activities carried out by both government and non-governmental bodies in space.

Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, told the Guardian it was “highly unusual” for a country to lodge a complaint through an “informational bulletin”.

SpaceX has launched more than 1,600 satellites into space in a network dubbed Starlink and has received permission from the US Federal Communications Commission to launch up to 12,000 satellites into space.

Collisions are not a rare occurrence in space, but such incidents have increased in recent years due to the number and speed at which satellites are being launched, according to McDowell. “Starlink is a big part of that,” he said.

He added that China was also a major contributor to space junk. “It is also fair to say that the US space station has several times over the past 10 years had to dodge pieces from the Chinese military anti-satellite test of 2007. It’s not like the Chinese had a clean record here. The biggest debris event ever was the Chinese anti-satellite test.”

The incident is a reminder that the world has entered a “new era in space”, the astrophysicist said.

“There’s more debris and there’s more active satellites. Things are just getting a lot busier and a lot more crowded up there … It’s a commercially dominated space age … where we’re stressing the space environment for the first time.”

SpaceX did not reply to a request for comment.

China’s space programme completed five successful manned missions in 2021.
