Just walk up and purchase a ticket when you arrive. We did. No line. I'm a "buy early online" kinda guy too but in this case it's truly NOT necessary.

Olá, oriento que faça essa pergunta diretamente à administração do museu.

Yes. I think so. As I mentioned the building itself is an attraction. And the museum itself is very comprehensive. Make the effort - you won’t regret it.

Durante a Copa os preços eram diferentes. Contacte diretamente o museu.

Мне кажется там можно сразу поучаствовать как набирается группа.

There is no requirement to book in advance.

wij hebben ter plaats aan de kassa kaartjes gekocht, niet duur 500 roebel. Het was in juli ook niet erg druk

I purchased the ticket at the museum.

You can access to the museum by Kaluzhsko - Rizhskaya Line metro and leave at Stantsiya Station (North vestibula) in Ostankinsky District. There is a high monument on rocket and you can immediately see it at a distance. Vice versa, you can also go to the museum by Moscow Monorail and leave at Vystavochny Tsentr station within walking distance. For more information, this museum is near to VDNKh Park and there is another metro station on the same metro line near to the park.
