Russian rocket retrogradation
By my calculations this marks the fifteenth failure of a Russian rocket in 6 years... The current version of the Proton has been around since 2001, and it's often associated with the word "workhorse." Soyuz dates back to the dawn of the space age, when an ancestor of the stalwart launcher sent Sputnik into space in 1957. Both rockets have evolved, but in terms of recent history, Russia's core launch fleet has remained relatively unchanged. So what's the matter with Russia's rockets?
