"What the hell is a space blog?" - Gene Cernan
It is good to know that Russia is making all attempts since 1960 to study Mars. Of course they have many failed attempts and yet to get the success, but their effort can't be under estimated. The difficult task like this can't be achived in a day. Every failure will teach them a lesson and will provide new ideas. This will help Russia to take a renewed attempt with more sophistication.
