According to anonymous sources, the Russian manufacturer of the Freget upper stage that failed yesterday during a Soyuz commercial launch has ordered a review of all Fregets.

The Lavochkin research and production association will check all manufactured Fregat boosters, a source in the space industry told TASS on Wednesday after a recent failed launch. “The Lavochkin Research and Production Association will check all Fregat boosters produced earlier. If defects are found, they [the boosters] will be sent for further development,” the source said.

The Lavochkin Research and Production Association did not comment on this information for TASS.

The problem is that Russia already spent almost a full year beginning in early 2016 checking all its rocket engines for substandard construction done by a corrupt manufacturer. Even though the Fregat is built by another manufacturer, did they not check the Fregat upper stages then also?

    Will this investigation delay any further launches from Russia this year? Would that mean that SpaceX wins the race for most launches?

    I’ve found this database over space debris and satellites and graphics of their current location and orbit. The yellow ones are simply called “objects”. The latest Fregat hasn’t been listed yet, it seems. I haven’t noticed the domain name “.space” before.

    Anatoly Zak is reporting an embarrassing suspected cause for Tuesday’s Soyuz failure — that the Fregat upper stage “did not have the correct settings for the mission originating from the new launch site in Vostochny, as apposed to routine launches from Baikonur and Plesetsk. As a result, as soon as Fregat and its cargo separated from the third stage of the launch vehicle, its flight control system began commanding a change of orientation of the stack to compensate for what the computer had perceived as a deviation from the correct attitude, which was considerable.”

    LocalFluff,
    Thank you for that link. What a nice display. Putting the mouse on them gives the identity, and I found a few representing geostationary satellites that I worked on. Clicking on one gives orbital information. What a fun link.
