Ukraine

NASA Administrator Charles Bolden insists the Ukraine crisis, which has the United States and Russia on opposing sides of a major international issue given the Russian move into Crimea, will not affect the deal NASA has with Russia to deliver astronauts to ISS and bring them home.

That may or may not hold true, depending on how things develop.  Russia needs the hard currency it gets for the flights, and it wants to be seen as a major space power, but it seems ready to pay a high price for Crimea.  On the other hand, the situation has moved some members of Congress to call for increased support for the companies developing private manned spacecraft so that Americans can get back to flying American ships as soon as possible.
