    That graphic is sub-par. Sputnik seems to be staffed by the same lamers as English RIAN. The nacelles are rendered wrong and
    the total number of launches is 401 and not 377. Total failures are 46. The 11.5% failure rate is mostly due to the f*cking Briz-M
    upper stage and I would put these failures in a separate category. There was also one clear case of sabotage. This is the recent
    spectacular failure in 2013 (https://www.youtube.com/watch?v=ZeS8GvLh1Jo). This and the ridiculous Briz-M failure rate are probably
    the same sort of "failure" by dirty tricks.

    They plan to use the Briz-M garbage on the Angara. Expect the same problems if they have not cleaned house.

    Agree with kvs, and I'll add that most of those failures happened early in the Protons development. Over the last 35 years, proton has been very reliable, with most of the failures in this period being related to upper-stage (eg Briz) or payload problems, with the occasional human-factor thrown in.

    Briz has had its share of problems, but they rarely seem to be caused by design issues - more like poor workmanship or outright malfeasance. Any Russian launch to geostationary orbit is always going to be more contorted than an ESA launch (from equatorial French Guiana) or NASA (from Florida) due to the latitude of Baikonur and the requirement of Briz to make more engine firings to change orbital inclination and deliver the payload. Briz has to work hard to acheive mission success and there is very little room for error or performance shortcomings (like a premature burn shutdown).

    Hopefully Krunichev have thrown enough resources in to fix the labour problems, and the FSB has managed to weed out those bastards who have been taking payments to throw a spanner in the works. Saboteurs are the lowest form of life and should be shot...

    First launch of upgraded Soyuz spacecraft may take place March 16, 2016

    The manufacturer plans to increase the solar cells’ power capacity and equip the spacecraft with new close-up, docking and attitude control engines

    MOSCOW, March 23. /TASS/. The first upgraded version of Russia’s Soyuz-MS spacecraft may be launched to the International Space Station in a year from now, a source in the space rocket industry has told TASS.

    "According to early estimates, the first launch of upgraded Soyuz may take place on March 18, 2016," the source said.

    TASS has no official confirmation of these plans.

    According to earlier reports the first launch of an upgraded Soyuz with a crew of Russia’s cosmonauts Alexey Ovchinin and Oleg Skripochka and NASA’s Jeffrey Williams on board was scheduled for May 30, 2016. Syrgey Ryzhkov and Andrey Borisenko, of Russia, and Robert Kimbrough, of the United States, are the standby crew.

    The Soyuz spacecraft’s manufacturer, space rocket corporation Energiya plans to increase the solar cells’ power capacity, and equip the spacecraft with new close-up, docking and attitude control engines, which will make it possible to approach and dock to the ISS even in case of one of the engines’ failure, and to guarantee normal re-entry and descent with two defunct engines.

    The spacecraft will be equipped with advanced communication and direction-finding systems. The spacecraft motion control and navigation systems will undergo the greatest changes. The new version will be equipped with GLONASS sensors. During the parachute descent phase and after the descent module’s touchdown the GLONASS/GPS coordinates will be transmitted to mission control via the satellite search and rescue system Cospas-Sarsat.

    Russian Defense Ministry needs new heavy carrier rocket — space agency

    A new carrier rocket capable of lifting cargos of 35-37 metric tons is to ensure the ministry’s needs to orbit heavy military satellites

    MOSCOW, March 24. /TASS/. Russia needs to create a new carrier rocket capable of lifting cargos of 35-37 metric tons for the Defense Ministry, a high-ranking official from the Federal Space Agency Roscosmos said Tuesday.

    The current fleet of launch vehicles does not ensure the ministry’s needs to orbit heavy military satellites, head of Roscosmos’ scientific and technical board Yury Koptev told journalists.

    "There are a number of projects in the interests of the Defense Ministry where we don’t ensure putting payload into target orbit, and we have to remove some apparatuses," Koptev said.

    The Roscosmos official said the new Angara-A5V rocket with an oxygen-hydrogen third stage will be able to put into geostationary transfer orbit 12-12.5 tons of payload, whereas an Angara-A5 with a hydrogen upper stage - only seven tons.

    According to a Roscosmos assessment, the cost of building a new modification of the Angara-A5V carrier rocket will be 37 billion rubles ($638 million).

    "This development will cost approximately 37 billion rubles," he said, adding that he entire program to create Angara-A5V with account for construction and fitting out all ground infrastructure for the carrier will cost 150 billion rubles ($2.6 billion).

    Delta Heavy, a promising US heavy lift launch vehicle, is expected to deliver cargos of 12-14 tons to the geostationary transfer orbit, the European Ariane 6 - 10-11 tons, and the Chinese heavy rocket up to 10.

    RSC Energia may offer Roscosmos the Sea Launch project
    Russian Aviaton » Wednesday April 8, 2015 16:55 MSK

    RSC Energia is considering the possibility of selling Sea Launch project to Roscosmos or a foreign company; the project may also be terminated due to bankruptcy, TASS reports with reference to a source familiar with the situation.

    “Among possible scenarios: selling the project to another country or an investor, “nationalizing” the project by means of upgrading the facilities for launching Russian launch vehicles (first of all Angara-A3) instead of US ones,” the source said.

    He also added that these scenarios might be integrated. For example, a foreign investor may fund the project and the facilities upgraded for launching Angara LVs may be located in one of the interested countries, he explained. The third scenario is bankruptcy, he added.

    Earlier RSC Energia President Vladimir Solntsev said that three scenarios of further development of Sea Launch project are being elaborated. He promised that the scenarios would be presented to Roscosmos “soon”; after that one of them would be submitted to the government.

    Sea Launch Company established in 1995 is the largest commercial international project for developing and operating a “floating spaceport” used to launch Zenit-3SL rockets with DM-SL upper stage manufactured by RSC Energia.

    95% of the company’s shares are owned by Energia Overseas Limited (subsidiary of RSC Energia (Russia)), 3% - by Boeing, 2% - by Aker Solutions (Norway). The company is headquartered in Nyon (Switzerland).

    The activities of the Sea Launch have been frozen.

    Terminate the project, sell off the assets and move onto better things.

    The idea had its run, to continue further would require further investment and co-operation with Ukrainian agencies and aerospace companies; however that sort of thing is no longer feasible now, which makes the project no longer feasible either and undoubtedly yet another source of potential pain and wrangling that is just not in any shape, way or form - worth it.

    Agreed.  Any project that puts cash into the pockets of the Banderistan regime (or helps maintain its ability to build rockets) is unacceptable.  It would be nice to see Sea Launch operating with Angara-A3 as a replacement but A3 development isn't proceeding, at least for the time being.

    Russia's new rocket will be named Fenix — source

    The new medium-class carrier rocket is planned to replace the Soyuz rocket family

    MOSCOW, April 27. /TASS/. Russia’s space agency (Roscosmos) plans to begin in 2018 the development of a medium-class carrier rocket to replace the Soyuz rocket family the creation of which had started during the USSR times when Sergey Korolev was the country’s chief rocket engineer, a rocket and space industry source told TASS on Monday.

    "Roscosmos is to prepare the technical design specification for the medium-class carrier rocket during 2016-2017. In 2018, it is planned to begin the experimental development work on this rocket named Fenix," he said.

    According to the source, in the period from 2015 to 2018 Roscosmos plans to spend more than 30 billion rubles (almost $600 million) on the project.

    Another source in the industry told TASS that the initiative of the new rocket development belongs to the Samara-based Progress rocket space center. According to preliminary data, it will be a one-piece carrier rocket with the capacity of carrying at least 9 tons of payload to a low-Earth orbit, that is, it will take a niche between the existing Soyuz and Zenit rockets. The Samara enterprise proposes to use liquefied natural gas as fuel, but also considers the standard kerosene and hydrogen option. In the future, Fenix is planned to be used as a module for creating carrier rockets of larger capacity. The groundwork of the Frigate upper stage manufactured by the NPO Lavochkin Research and Production Association may be used for the new rocket’s booster.

    According to the source, the creation of a new medium capacity rocket was necessitated by the fact that in the future the national space program will use the Angara modular rocket. However, if a contingency occurs during the launch of a light-class version of Angara, the launches of the entire family of the carrier rockets will have to be suspended until the investigation is over, the source said. It is necessary to develop a new rocket as a reserve to ensure orbiting of small and medium payloads, he added.

    Roscosmos chief Igor Komarov said previously that a new draft of the Federal Space Programme for 2016-2025 included the works for the creation of a new-generation medium-class carrier rocket.

    Great.... they don't need another rocket of the same class. 

    I really hope the "if a contingency" statement is a joke or something. If the universal-segments as a whole are experiencing problems consistently, then obviously there is a design fault and delays are needed. But if it is just one launch... why bother.

    Russia’s participation in Baiterek space rocket complex creation is decisive — Kazcosmos

    ASTANA, June 1. /TASS/. Kazakhstan is ready to continue the implementation of the project for the creation of the Baiterek space rocket complex and its further financing even with increases costs, Deputy Chairman of the Aerospace Committee (Kazcosmos) of the Ministry of Investment and Development of Kazakhstan Meirbek Moldabekov told TASS in an interview on Monday. However, he said, it is possible only on the condition of the "preservation of the status of the joint project and the Russian side’s participation in it on a parity basis."

    "We are currently in negotiations with Roscosmos (Russia’s Federal Space Agency) on these two key issues. We expect to hear Roscosmos’ official position tentatively in the first half of June," Moldabekov said.

    Referring to the change in the project cost, he said that it is currently "impossible" to specify the sum. "This requires justified estimates that we don’t have at present. These calculations should be presented by our Russian partners. The feasibility study and a number of expert examinations will be conducted on their basis. Only after that it will be possible to speak of about any specific figures and the sum of the project cost increase," he said.

    According to Moldabekov, "In addition to the issue of funding, the factor of the project joint implementation is equally important." "The degree of interest and participation of Russia in this project is a key issue for the Kazakh side at present," he said.

    According to plans, the Baiterek space rocket complex is to be created on the base of Baikonur spaceport by 2022. Joint proposals between Kazcosmos and Roscosmos to implement the project were approved during the second session of the Kazakh-Russian intergovernmental commission on the Baikonur complex held on November 24, 2014. In his annual address to the people, Nazarbayev said that the state should expand its role in the global space market by 2030 and bring a number of ongoing projects to fruition. This includes constructing the spacecraft assembly and test complex in Astana, establishing the space system for remote sensing and a national space monitoring system and ground infrastructure system for high-precision satellite navigation.

    The Baikonur complex, which includes the launch site, was founded 60 years ago. On June 2, 1955, by the directive of the General Staff of the USSR Armed Forces, the organisational and staff structure of the Research Test Site No 5 was approved. This day is considered Baikonur’s establishment date. In 2014, Baikonur once again received the title of the most used spaceport in the world. Twenty-one rockets were launched from Baikonur in the past year, 19 of which were successful. Cape Canaveral in the United States followed with 18 launches, all of which were successful.

    One rocket class is all that is needed. The idea in Russia seems to be is building of various classes, which is silly and very costly. Bulava vs Liner, Angara and Fenix, etc. Stick to one class and expand it. If another plant needs work, get them to work with the one making the rocket and so both get work and overall costs get reduced rather than two different rockets.

    Russia's Soyuz-2.1a rocket to be launched first time after loss of Progress — source

    The launch of the cargo space vehicle Progress is scheduled for early July

    MOSCOW, June 5. /TASS/. A Soyuz-2.1a space rocket is to be launched from the northern Plesetsk space site on Friday for the first time since the loss of the Progress cargo vehicle last April, a source in the space rocket industry told TASS.

    "A launch of the Soyuz-2.1a carrying a military satellite will be carried out from the Plesetsk space site at 18:24 Moscow time, the source said.

    The launch of the cargo space vehicle Progress is scheduled for early July.

    "As far as Progress is concerned, we have already said that the launch of a cargo vehicle is due early July," Komarov said. "And a manned launch from Baikonur will be planned at the end of July."

    Russia Plans Proton Rocket Launch for August After Series of Failures

    The first launch of the Proton carrier rocket after the most recent failure is planned for August, head of Russia’s space agency Roscosmos Igor Komarov said.

    BAIKONUR (Sputnik) – "The next ‘Proton’ launch is planned for August. It will be a commercial launch," Komarov said early on Thursday without specifying what kind of spacecraft the rocket will carry into orbit.

    According to Komarov, both the rocket and the vessel are already going through flight preparation at the Baikonur space center in Kazakhstan.

    On May 16, a Proton-M carrier rocket was to deliver the Mexican MexSat-1 satellite into orbit, but shortly after launching, the rocket lost its telemetry with Earth and later burned up in the atmosphere upon reentry.

    The failed launched was the latest of seven Proton carrier rocket failures over the past five years.

    Komarov said in May that Russia was not planning to give up on the use of Proton-M rockets despite the malfunctions.

    The Proton-M is the largest carrier rocket in Russia's fleet of space launch vehicles. The rocket has lifted dozens of Russian-made and foreign satellites since it was first launched in 2001.

    Hopefully they actually will have solved the issues with this particular model. IIRC it had to do with vibrations destroying the turbopump in the third stage.

    I would dispute the accuracy of this statement.  As far as I can tell, the following is the list of all proton failures over the last 25 years:

    16 May 2015 (Mexsat-1)

    I would dispute the accuracy of this statement.  As far as I can tell, the following is the list of all proton failures over the last 25 years:

    16 May 2015 (Mexsat-1)
    15 May 2014 (Ekspress AM4R)
    2 July 2013 (Uragan-M #748-750 Glonass)

    27 May 1993 (Gorizont #39L)
    9 August 1990 (Ekran-M #14L)
    That is an interesting list. Of all the 16 failures in the last 25 years, 6 were in the last 5 years, and more than half (9) in less than one decade (since 2006). The Proton was extremely reliable from the 80's up to the early 2000's, but for some reason (most likely bad quality control in production) it lost its reliability in the last 5 years.

    The issue had to do with vibrations within the rocket, and sensors not picking it up... Said vibrations basically stressed the turbo-pump to the point of failure. I don't know why some launchers went well and others didn't, probably just the quality of the turbo-pump used.

    This list includes the pure sabotage case of July 2, 2013. One or more of the key sensors were hammered backwards. This
    is not QC, this is deliberate. This begs the question how many of the other "QC" cases were sabotage as well.

    Yes, I still believe that the loss of the 3x Glonass in 2013 was an act of sabotage. I simply do not accept that the yaw sensor module could be installed upside down by error. Does anyone know if there has been any public announcements in this matter, or has anyone been arrested?

    Its noticeable that we have had 1 failure per year since 2010, and I suspect that a large part of the problem may be the loss of experienced engineers as they reach the end of their productive careers. Space industry has been starved of funds since 1991, and the brain drain has been detrimental to Russias' capabilities given that the Russians tend to emphasis the importance of skilled individuals within the organisation rather than a rigorous and prescribed systems-based approach like that of NASA.

    Actually, the sensors did pick up the vibrations, and the telemetry proved the cause of the failure.  Shutdown of the failing turbopump is not an option however this would lead to certain payload loss.  There is no option but to let the engine run and hope she holds together.

    The actual cause of the failure was a design error - specifically the material specification of a bearing was inadequate. Under certain abnormal operating conditions (they were not specific) the bearings softened and distorted, leading to vibration. The cause was suspected on previous failures, and the vibr sensors added to monitor and confirm the diagnosis.

    Russia may use new Angara carrier rocket in Sea Launch project — space firm

    At least two options are being discussed to adapt the floating Sea Launch platform and the Angara carrier rocket, the chief designer said


    MOSCOW, July 28. /TASS/. Russia’s promising Angara-A3 medium-class carrier rocket may be used in the Sea Launch project instead of the Russian-Ukrainian Zenit rocket, the chief designer of the Khrunichev Space Center, which is the Angara developer, told TASS on Tuesday.

    "So far, this idea remains. We should wait for some decisions, after which it will be possible to have a serious talk about something," Alexander Medvedev said.

    At least two options are being discussed to adapt the floating Sea Launch platform and the Angara carrier rocket, the chief designer said.

    "For example, we keep the A-3 [rocket] unchanged but we adjust and change the equipment earlier installed on the platform. According to the other option, we keep the equipment unhanged but in this case it will be necessary to change the Angara-3 configuration considerably. We’re not forcing the events and are simply considering both options concurrently," he said.

    Sea Launch Company was established in 1995 by US Boeing, Russia’s Energiya Rocket and Space Corporation, the Norwegian shipyard Kvaerner (now Aker Solutions) and the Ukrainian Yuzhnoye design bureau and Yuzhmash production association.

    Sea Launch declared its bankruptcy in 2009 and in 2010 the Russian enterprise assumed the leading role in the project. However, the company announced the suspension of launches in the summer of 2014.

    Russia’s Federal Space Agency (Roscosmos) Head Igor Komarov said earlier Sea Launch could be rebased from California to Brazil but the prospects of the project remained uncertain over litigation with Boeing.

    Russia plans to create reusable rocket for satellite launches?

    the translator is pretty bad, but that is my impression from what was translated, anyone who speaks Russian can verify?


    Roscosmos plans to establish a repeated the rocket ship to formulate satellites in orbit. A new rocket will include cruise the first stage, which after separation from one-time of the second stage of commits a return to the area of the launch.

    Роскосмос планирует создать многоразовую ракету-носитель для выведения спутников на орбиту. Новая ракета будет включать крылатую первую ступень, которая после отделения от одноразовой второй ступени совершает возврат в район старта.
