I have a 10 hour layover in Moscow before my next flight? Can I get a temporary visa?

I have a 10 hour layover in Moscow before my next destination, I have never been to Russia and would like to tour around Russia with what little time I have. Can I have a temporary visa issued at the airport that would allow me to go outside? I live in USA, so would I need to go the the Russia Consulate in the US and get the visa? Thank you.
