First man in space. First group flight to orbit. First female astronaut. First spacewalk. All these breakthroughs of the USSR took place thanks to the manned spacecraft Vostok and Voskhod. Today we are no longer fully aware of what scientific feat these first orbital flights were and with what colossal risk were associated: 10-fold overloads and temperatures up to 3500 °, insufficiently studied consequences of weightlessness and cosmic radiation. The trajectory of the ballistic descent, angles of attack and temperature regime began to be calculated on manual electromechanical arithmometers, and out of seven test launches that preceded the triumph of Yuri Gagarin, only three were successful. No wonder many years later Boris Chertok admitted that "today I would never sign a security guarantee" for the launch of the first cosmonaut and that only "having gained vast experience, I realized how much we risked then..." In the new book of the leading cosmonautics historian, you will find comprehensive information about the first manned spacecraft of the USSR and the training of the first cosmonauts.
