Russian engines RD 181 is not the most expensive for REGULAR flights to the MKS stasion
All in the Russian segment of the Internet one say that America without Russian space engines RD-181 will not be able to do anything in space. I guess it is at least a tale in which Roscosmos would like to believe. In fact, the US is implementing a wide range of programs that use different missiles and engines, and not always the choice falls on the Russian RD 181. If it is profitable to drive to the ISS on Russian engines, then you can buy Russian, and if you do not fly to Mars on a Russian rocket because of its high cost, it is also a fact. In addition, the Americans are patriots and they are trying to develop their private space exploration, and have not yet created an analogue of RD 180, like buying in Russia. When you create, this engine or anyone will not take, this is also necessary to think about and have enough to fly into space on a horse-drawn born in the last century.
Now actually about the news itself, America in the face of NASA representatives does not deny the opportunity to continue to buy engines from Russia to serve the American segment on the ISS. Engines that put on spacecraft series Union reliable and it would be superfluous to give up the opportunity to use someone else`s experience for the benefit of the development of its space. American private space does not stand in one place, engineers in all create new models of space technology, but at the same time still believe that if it is more profitable to buy than to do it yourself, it is worth buying.
Of course, NASA has such hawks, which under any circumstances would like to fly on their engines to the MKS, even if the loss itself. So probably it was before, at a time when the White house in the main post of businessman, doing everything for a profit for the country, despite the talk and gossip in the press.
While the agreement between Russia and the United States on the delivery of astronauts to the MKS is in effect, the Russian Unions will earn money. This is so to say for now, but it is worth thinking about the future, as SpaceX and Boeing are actively working on their means of delivery of astronauts to the ISS and if you believe analysts, then in 2019, the us space delivery vehicles will expand significantly in the proposals. While NASA does not have expensive means of delivery of astronauts to the ISS, but it seems so far, in the near future, everything can radically change in the other direction. And to be honest, I do care about who and whose engines are flying, as well as who and how much money earned on this:) and if you quote the statements of academician Tyunyaev, then there is no space at all and fly as if not where, and the earth has the shape of a bowl. So that the news is not at all interesting.
