Note: In 1965, three civilian journalists were selected for cosmonaut training in preparation for flight on a Voskhod mission. When the Voskhod program was canceled, Golovanov and Letunov were dismissed. Rebrov, on the other hand, stayed with the space program as a journalist until 1974.

June 1 - Medical Group 2 - USSR

Yevgeni Illyin, Aleksandr Kiselyov, Yuri Senkevich

Note: These physicians were selected for the long-duration Voskhod flights, all of which were subsequently canceled to make way for the Soviet Moon program. All three were dismissed at the beginning of the following year.

June 28 - NASA Group 4 - The Scientists - USA

Owen Garriott, Edward Gibson, Duane Graveline, Joseph Kerwin, Curt Michel, Harrison Schmitt

Note: Graveline and Michel left NASA without flying in space. Schmitt walked on the Moon on Apollo 17. Garriott, Gibson and Kerwin all flew to Skylab. Garriott also flew on the Space Shuttle and was the first Amateur radio operator to operate from orbit.

October 28 - Air Force Group 3 - USSR

These included military programs (with and without the Almaz/Salyut space stations) and two lunar programs (only one of which aimed at an actual lunar landing). In the end, only the orbital program and the space station program went ahead, and few of the cosmonauts from this group ever were given the chance to fly.
