I am planning a brief tourist trip to Moscow. I want to go and see most of these following locations, Kubinka Tank Museum, Monino Air Museum, Tretyakov Gallery. On New Years Day, I think the only things open are the Aquarium and Moscow Zoo. Secondary tourist spots are Cosmonaut or Victory Museum, open to anything else. I don't know if I will go to Petersburg, but I am thinking of  cruiser Aurora and the Tsar Fortress.
