Born in Porfiryevk, Crimea in the Ukraine, Nelyubov was a captain and pilot in the Soviet Air Force. He was selected as one of the original 20 cosmonauts on March 7, 1960 along with Yuri Gagarin. The following year, six of the original twenty were evaluated for assignment on Vostok flight crews between January 17 and 18; Gagarin, Titov, and Nelyubov are considered the top three candidates

For Vostok 1 Nelyubov was chosen as second double for Gagarin and presumably first double for Vostok 2 for Titov in April and August 1961 respectively. For the dual launches of Vostok 3 and Vostok 4, Nelyubov was again chosen as a double for Andrian Nikolayev and Pavel Popovich.

On March 27, 1963 Nelyubov, Anikeyev and Filatyev were arrested for drunk and disorderly conduct by the militia at Chkalovskiy station. According to reports, the officers of the security patrol that arrested them were willing to ignore the whole incident if the cosmonauts apologized, but Nelyubov refused, and the matter was reported to the authorities. Because there were previous incidents, all three were dismissed from the cosmonaut corps on April 17, 1963, though officially not until May 4, 1963. Nelyubov never completed a space mission.

Following dismissal he went back to flying interceptors in Siberia but fell to drinking and depression. He died on February 18, 1966. While drunk, he stepped in front of a train near the Ippolitovka station, northwest of Vladivostok. It was officially ruled a suicide.

To protect the image of the space program, efforts were made to cover-up the reason for Nelyubov's dismissal and his following suicide. His image was airbrushed out of the famous "Sochi Six" photo which showed the top members of the original class of Soviet cosmonauts. This airbrushing led to early Cold War speculation about reasons for the removal even though actual reasons were often mundane.
