Come see dude inv me <| sep |> I ' m aware Tass is owned by the Russian government . However this isn ' t an article saying that Russia will build this , but rather proposing that an international mission is the most likely solution , and that it won ' t happen till the 2040 ' s . I think that claim removes most of the bias from the article . I agree with your findings regarding radiation , although it ' s honestly still more than I ' d like to give any travellers or colonists As for weeks vs months , depends on the drive . I ' ve seen studies saying that a 34 week journey is possible with nuclear propulsion systems . The deltav required is insane , but depending on your drive it ' s possible . Russia has signed both the Partial Nuclear Test Ban Treaty and the Outer Space Treaty . I can ' t remember which of these it was , but one of them bans nuclear development in outer space . Therefore Russia has similar obstructions to spacerelated nuclear development as the USA . I don ' t remember whether China is also a signatory to these treaties
