    we here from Muscovite media , day after day, how and what they can do with the USA and Free world in general , but here is reality which shows in which technical shape Muscovite empire today " "Russia" stole precious metals from rocket engines.":

    "
    Almost all the engines of the second and third steps were defective.

    All previously produced engines RD-0210/0211 and RD-0213/0214, designed for installation on the second and third stage of a Russian rocket proton-M, will be rebuilt. This was stated by Director General of Scientific production Association Energomash Igor Arbuzov, RIA Novosti reported.

    “The Proton is a 71 engine, or almost the entire groundwork for the second and third steps. Currently signed schedule, most of them will be held in 2017, but we understand that some portion will inevitably go for 2018,” said he. First deliveries of the refurbished units will begin in may .

    Arbuzov noted that it is necessary “not to disrupt the schedule of launches for the Federal space program starts in the interests of the Russian Ministry of defense and commercial launches, and also provide the necessary groundwork for compliance with the schedule of delivery of new crew and cargo to the International space station.”

    As reported Корреспондент.netin Russia stole precious metals from rocket engines. According to the media, we are talking about tens of engines of the carrier rocket proton-M. Technological problems with the engines emerged during the fire tests."http://true-news.info/in-russia-found-more-than-70-defective-engines-for-the-proton-rocket/

    do you think think that Muscovy can pull it off ?) comments ?

    Russian rocket builder may have replaced special alloys with cheap metals
    Implications for NASA, which relies on Russia for crew transport, remain unclear.
    n recent years, the Russian space program has had a series of problems with its flagship rockets, the heavy-lift Proton booster and the smaller Soyuz rocket used to launch crews and cargo to the International Space Station. The Proton rocket has been grounded since last summer, and the Soyuz has not flown since December, when its third stage engine failed and a Progress cargo spacecraft was lost.

    Most of these problems have been traced to engines that power the second and third stages of the Proton and Soyuz rockets. The majority of these engines are built at the Voronezh Manufacturing Plant in southwestern Russia, near the Ukrainian border. Russian Space Web reports that Ivan Koptev, director general of the engine manufacturing facility, has resigned.
    According to the news reports, the final straw may have come after recent tests of engines to be used by future second and third stages of the Proton rocket that resulted in more failures. "The failure of the engine was reportedly traced to illegal replacement of precious heat-resistant alloys within the engine's components with less expensive but failure-prone materials," Zak writes. The Russian space agency, Roscosmos, has already recalled some of the engines to be used in the upper stage of its Soyuz rockets, and now it is also recalling dozens of Proton upper stage engines. The next Proton launch could be delayed into this summer.

    It is not clear what implications this will have for NASA, which relies on the Soyuz rocket to launch its astronauts to the International Space Station. NASA's head of human spaceflight, William Gerstenmaier, is in Russia this week to meet with Roscosmos officials to discuss the failure of the December 1 launch of the uncrewed Progress cargo vehicle. Although cargo and crew launches take place on different variants of the Soyuz rocket, the two rockets share a common third stage, which is where the December failure occurred.
