The following events took place in 1964 CE, or Common Era.
- The Soviet Union launches Voskhod 1, humanity's first multi-person spacecraft, on October 12. Its crewmembers become the first humans to enter space without spacesuits, due to the craft's limited cabin space. Two days later, Premier Nikita Kruschev is deposed by a group of high-ranking Communist Party members led by Leonid Brezhnev. Brezhnev cuts the Voskhod program in half and orders the Russian space program to refocus its efforts on reaching Luna.
