America has intervened in the matter of Russia and Ukraine and has talked on Russia's actions in Ukraine. This has led to a diplomatic crisis between Moscow and Washington.

The matter has very well highlighted the dependence of US on Russia when it comes to space programs. Professor Roger Handberg from the University of Central Florida said, "Space is a secondary thought in this, but, yes, we are very vulnerable to having something go bad. It all is going to depend on how the politicians sort it out".

Experts have different opinions on the matter. Many of them have said unless things get really worse, Russia would not use space assets for its political leverage. If such a thing takes place then there are chances that the US also might take actions and one of them could be withdrawing astronauts from training in Russia.

NASA has also spoken on the matter and said nothing has changed with the Russian space agency. Their relationship with the Russian space agency is going on as it was. It can be evident from the fact that preparations are being made to land an astronaut and two cosmonauts Monday.

"People lose track of the fact that we have occupied the International Space Station now for 13 consecutive years uninterrupted, and that has been through multiple international crises", said NASA Administrator Charles Bolden.
For now, everything is going right. But if something goes wrong, then Bolden said they will go into contingency planning.

Earlier, it was considered that it is the US which is heavily dependent on Russia for rocket engine technology and human access to space. But no more, say experts. They said NASA pays considerable amount for each astronaut's seat on a Soyuz spacecraft and pays heavy amount for purchasing engines. Both the factors act as a great source of revenue for Russia's space industry.
