An anonymous reader writes: The Verge reports on an internal memo from NASA indicating that they've suspended all contracts and activities with Russia that aren't involved with operating the International Space Station. Quoting: 'Given Russia's ongoing violation of Ukraines sovereignty and territorial integrity, until further notice, the U.S. Government has determined that all NASA contacts with Russian Government representatives are suspended, unless the activity has been specifically excepted. This suspension includes NASA travel to Russia and visits by Russian Government representatives to NASA facilities, bilateral meetings, email, and teleconferences or videoconferences. At the present time, only operational International Space Station activities have been excepted. In addition, multilateral meetings held outside of Russia that may include Russian participation are not precluded under the present guidance.'
