Washington Post: Deputy Prime Minister Dmitry Rogozin announced yesterday that Russia will no longer sell rocket engines to the US if they will be used for military launches. He also indicated that Russia will end its participation in the International Space Station (ISS) in 2020. The announcement comes just days after a US court ended an injunction against the purchase of Russian rocket engines by United Launch Alliance. US–Russia space program collaboration had already been stressed by the sanctions the US imposed in response to Russia's actions in Ukraine. Meetings between the space agencies and work on international programs such as Boreal Forest research had already been suspended. NASA is currently dependent on Russia for launching manned missions to the ISS, and that contract is still intact.
