Things are not going smooth since Russia took over the control of Crimea from Ukraine. Russian officials have condemned the action of Europe and United States and have also threatened the cooperation with the United States in space technology.

The US and Europe levied trade sanctions on Russia. One the other hand, Russian President Putin and his associates banned rocket sales to the US military. "Russia is ready to continue deliveries of RD-180 engines to the US only under the guarantee that they won't be used in the interests of the Pentagon", affirmed Deputy Prime Minister Dmitry Rogozin.

Russia has also asked the US to make an arrangement to ferry their astronauts up to the International Space Station after 2020. It is not the end of the harsh moves planned by Russia.

Russia has also threatened to shut down the 11 Russian-based GPS stations meant to enhance the accuracy of missile and satellite launches. The warning bell has been rung after the US showed reluctance to host reciprocal stations for Russia's alternate positioning system, GLONASS.

GPS ground station in Russian territory would get off on June 1 if the US does not allow Russia to have similar stations for GLONASS in the former nation.

Rogozin raised concerns over development of high-tech projects with the United States. He termed the US to be an undependable partner and alleged the nation for politicizing everything.

United Launch Alliance (ULA) uses the RD-180 rocket engine and it is also the US Air Force's only supplier of rocket launches to power its Atlas V rocket.
