Borisov was Deputy Prime Minister. Almost two weeks ago, the Kremlin named him space chief, succeeding Dmitri Rogozin. He argued a lot with western countries about the war in Ukraine. For example, he threatened that Russia could sink the ISS. He had the life-size letters Z and V affixed to the launch installation in Baykonur, the symbols that Russia also used in the war. Roskosmos also shared a video in which the Russian part of the ISS was disconnected from the rest. As a result, the non-Russians were left alone in the universe.
NASA
The American space agency NASA says it has not heard anything from Russia about ending participation in the ISS.
The ISS has been in orbit around the Earth since 1998. It is a cooperation project of Russia with the United States, Europe, Canada and Japan. The western countries partly depend on Russia to bring crew members to the space station. Russia in turn can make good use of the income from this. Other space projects of Russia with other countries have been stopped because of the war, such as a mission with Europe to Mars.
