BBC News - Ukraine crisis sends a chill into orbitNow, the Russians have hit back by saying they will stop the export of rocket engines to the US if they're to be used to launch American military hardware – something they routinely do when attached to the first-stage of the Atlas rocket.
Several of these vehicles a year will loft spacecraft for the US Air Force or the National Reconnaissance Office (NRO).
Russia is also going to shut down 11 ground stations on its soil that are used to maintain American Global Positioning System (GPS) satellites, although Moscow says this is more directly a response to Washington's refusal to allow stations to be built on US soil for Glonass, the Russians' own sat-nav network.

This sucks. Didn't we pay for a majority of the space station? The fact that we are importing rocket engines from them is interesting too.
