Khrushchev

Nikita Khrushchev was at the height of his powers.

In 1956 Khrushchev denounced Stalin's crimes.

After his successful space flight, the Soviet Union paid its official thanks to Yuri Gagarin. There was a six-hour parade through Red Square, followed by a ceremony at the Lenin Mausoleum where Gagarin was greeted by General Secretary Nikita Khrushchev.

After the demise of Stalin, Korolev gained the support of the new leader, Nikita Khrushchev.
