In the small park across on the other side of Ostankinsky Proezd from the Kosmopark is the Sergey Korolev Memorial House-Museum. It is located in the house where the space scientist Sergey Korolev lived and worked from 1959 to 1966, having been given it by the state after the successful launch of the world's first satellite - Sputnik 1 - in 1957. The interior of the house has been preserved since Korolev's time there and many of his personal belongings are on display, including his note books and his extensive library. The museum is run as a branch of the Cosmonautics Memorial Museum.  Admission to the museum is free on the third Sunday of the month.
