    By the end of 1950s, the Soviet Union’s science level had reached a remarkable level and the government decided to have a go at a human space flight and select candidates.

    Above: Soviet pilot-cosmonaut Alexei Leonov training in the centrifuge at the Yuri Gagarin Cosmonaut Training Center.

    On March 7, 1960, the Soviet Union completed the formation of its first squad of cosmonauts, paving the way for space exploration. Just a year later, Yuri Gagarin, one of the team’s members, became the first human to enter space.
