Two fresh failures of russian space.

Another proton failed. It seems to have dropped somewhere in China. Launch video seems to show some problem immediately after launch. But worse news is that a Briz upper stage failed. That is the same family of upper stages that failed on the last Progress resupply mission for the ISS and is needed for Soyuz manned flights as well. The flight was carrying MexSat-1 a satellite built by Boeing for the mexican government.

Also a planned ISS reboost failed for yet unknown reasons.

Until they fix this unreliable upper stage the existence of ISS may be in jeopardy. The last sentence is my personal comment only.
