Fun bit: on the http://sysoev.ru/ the news starts with "Поехали!" (Let's go! / Let's ride!)—Yuri Gagarin quote from
the launch of the first manned space flight fifty years ago.
Heh - off-topic, but that reminds me of a story involving the same idiom. A friend told me that in the 80s she spent some time as an exchange student in Moscow and they would go see movies on Friday nights. Occasionally there would be an American movie dubbed into Russian (all the parts played by the same Russian male voice who would read everything in a deep monotone) and one time it somehow turned out to be a trashy zombie movie. They get to the obligatory "teenagers in the cemetery in the middle of the night" scene and when the zombies appear, one of the teenagers yells "Holy shit man, let's get the fuck out of here!" This gets translated by the monotone Russian baritone as: "Пошли" (let's go).
