What's Happening to the Russian Space Industry?, Commercial Space Watch
"On the morning of August 6, the Russian space industry woke up to yet another failure in a long list of failures over the last 2 years. 2 months later, on October 16th that failure became a catastrophe with the explosion of the Briz-M upperstage. Are we witness to the end of the dominance of the Russian space industry?"
Marc's note:Further down in the article when discussing the Briz-M "break-up" and the ISS.
"The differing rates at which the two orbits precess around the Earth's polar axis mean that the ISS orbital path will periodically move in and out of the debris cloud, and will sometimes spend several days at a time with a large part of its orbit within the cloud.
Depending on the actual number of fragments, this event may eventually be considered to be the most dangerous fragmentation event ever to have occurred in space."
