Let's have this hypothetical scenario discussed. That instead of Soviet Union landed first man on the moon at 1970, US actually won the first base of Space race somewhat earlier.
We all knew that US end up saying "We're aiming for Mars anyway", landed their own at the moon in 1971 and landed first man on Mars in 1993, beating Soviet Union who only able to do that in 1995...
But said that US win the race to the moon instead, will the Soviets end up focusing on Mars first instead. And what is your best guess for the Mars landing to happen?
