Russia Close To Findings On Soyuz and Proton

First time accepted submitter neBelcnU writes "It's still early, but there are findings for the recent losses of a Proton and Soyuz rockets. There was a procedural error in the Proton's flight planning, and the 3rd stage gas-generator is the center of attention in the Soyuz. From the article: 'The Soyuz investigation has not formally issued its findings or recommended corrective actions. A launch schedule for the next manned flight to the International Space Station will not be decided until the commission completes its work.'"

Which is using hydrogen peroxide and potassium permanganate to drive them, just like the old German V2 rocket IIRC..

No it isn't! While that's true of the RD-117/RD-118 engines on the first stage and boosters the upper stage's RD-0110 uses its Kerosene and LOX to produce the hot gasses.
