Since 2011 - the time of Agency Aerospace America (NASA) food fotography decided to abandon the spa

The United States is heavily dependent on imports of Russian rocket engines for military cargo and people into space. This is the key to Moscow in retaliation for Washington to impose sanctions. food fotography
Since 2011 - the time of Agency Aerospace America (NASA) food fotography decided to abandon the space shuttle program, Washington was totally dependent on Russian Soyuz spacecraft food fotography to take astronauts to and return from the International food fotography Space Station (ISS).
Even installing GPS systems in cars, cell phones and all of America ATM systems are also dependent on Russian technology. food fotography The launch of weather satellites or satellite missile early warning by the U.S. and Russian companies to undertake. Russian Soyuz Spacecraft
In the context of the political crisis in Ukraine is becoming more profound and sanctions "tit for tat" began to be enforced, many people believe that the U.S. is gain the upper hand as compared to Russia.
As an economic powerhouse and No. 1 in the world trade volume between Moscow - Washington every year is quite low, Americans are confident to give sanctions to isolate the diplomatic field and the Russian economy.
However, Russia has a separate entry in response to U.S. sanctions. Professor of diplomacy at Harvard's Kennedy School of Government once said: "They (Russia) there are many ways to respond to sanctions and the measures that we are at a disadvantage."
One of the disadvantages for the U.S. today is the ability to Russia will force manufacturers to stop selling the NPO Energomash engine RD-180 liquid fuel for America. Meanwhile, the RD-180 engine is currently being used by the U.S. to operate the Atlas V rocket that carries military cargo and people into space.
"The Russian rocket engine to achieve the best quality in the world. food fotography RD-180 engine achieved the best performance and the lowest cost to the U.S. to deliver goods safely into space," leads the Global food fotography Post Royce said Dalby, space systems expert and director of the management consulting firm defense and aerospace Avascent in Washington.
Although the price of the RD-180 engine was "kept secret" but U.S. experts estimate its value at about 11-15 million USD / engine. Average annual American reporter from 8-9 satellites with missiles Atlas V.
According to experts Dalby, within 24 months, the U.S. will use the Atlas V rocket to launch four spy satellites for the National Scouting Center (NRO), food fotography a satellite image, two weather satellites, 4 GPS satellites, 3 military satellite communications, two shipping services for the Air Force and a NASA scientific satellites. Each year, Americans spend more than $ 400 million to Russia put astronauts on the ISS
"No RD-180, this is a disaster for U.S. national security. Boosters Atlas V is the essential means to transport the goods to the civilian and military space," said John Logsdon, a light establish policy and director of the Institute of Space at George Washington University, said.
When asked whether DOD should increase budget expenditures for the development of rocket engines in the context of domestic tensions - Russia heats around the political crisis in Ukraine, Mr. Hagel for that the development process food fotography and production of the new engine will consume a lot of time and money.
However, United Launch Alliance (ULA) - a joint venture between Lockheed Martin - Boeing said the U.S. does not need to worry about supply food fotography interruptions food fotography by ULA still capable of providing the RD-180 engine in than 2 years. Song, ULA spokeswoman, Ms. Jessica Rye stressed today, this company has no engine RD-180 replacement if stopped imports. While the new engine food fotography manufacturing will take between 4-5 years.
After the Soviet Union collapsed in the '90s, companies and organizations of the United food fotography States food fotography has poured billions of dollars to help Russia maintain industry aerospace. Especially in the field of space technology, Washington has encouraged scientists to Russia not to sell gray matter to other countries.
But over time, the relationship Russia - America has gradually shifted from cooperation to confrontation, especially after President Vladimir Putin came to power in 2000. Example, Russia threatened to stop supplying each rocket food fotography engine RD-180.
In 8/2013 when U.S. President Barack Obama threatened Syrian troops entered the military after accusing President food fotography Bashar al-Assad using chemical weapons attack civilians, food fotography Russian media reported that Moscow food fotography is considering ability to continuously remind the program provides food fotography RD-180 for Washington.
Currently, U.S. experts are giving many alternatives for the RD-180 engine including Russian rocket SpaceX Falcon Group. However, the size of the Falcon too small and can not carry the majority of military cargo such as name
