The International Space Station had to perform a manoeuvre in order to avoid a collision with space junk, left by the Chinese Fengyun-1C satellite, the Russian State Space Corporation Roscosmos reported.
"The orbital altitude of the ISS was raised on Wednesday evening to avoid conjunction with space debris. According to preliminary data, the manoeuvre has raised the station's orbit by around 1.2 kilometres", the statement said.
The Chinese satellite was destroyed in 2007 in an anti-satellite missile test. It exploded into more than 3,500 pieces of debris, most of which are still orbiting the planet.
