Moscow is not even close to the places where the most Russian space launches are being performed. However, Moscow has a bunch of scientific research centers and universities which contribute to the technology, so there is a place in Moscow where real life rocket engines are stored, right
in the university. This is a post of a trip to such a place which Svetlana (the author) made on a day known as "Cosmanautics Day" in Russia. This place is not a museum and generally is not open to the public. Special permission is needed to obtain a ticket there.
