Vostok 5’s orbit turned out to be lower than the expected 181 by 235 km. The actual orbit was 175 by 222 km. Initial calculations indicated the orbit of Vostok 5 would not decay for 10 or 11 days, however more conservative estimates, taking into account the increased solar activity and the resulting expanding of the upper atmosphere showed that the orbit could decay after only 8 days. With no way of predicting where Vostok 5 might land, the planned eight-day mission was now in question…
In June of 1963, the Soviet Union performed an encore of the Vostok 3 and 4 missions with two manned spaceships orbiting the Earth simultaneously. However, Vostok 5 and 6 was more than a simple repetition. Vostok 5’s objective was to beat the flight-duration record. But Vostok-6 would carrying the first woman into space. The 26 year old Valentina Tereshkova….
In February of 1962, the United States put John Glenn into orbit. This prompted Soviet leadership to suddenly asked Chief Designer Korolev to launch the next space spectacular promptly. To make this mission truly spectacular the Soviets decided to launch a group flight of two Vostoks lasting up to four days in orbit.

Following the successful suborbital missions of Allan Shepard and Gus Grissom, NASA believed the Mercury capsule was ready for an orbital mission. But, there was a problem, the Redstone booster did not have the power to place the Mercury capsule into orbit. The Atlas booster had the power to put the capsule in orbit but not the confidence of NASA. By September of 1961 Four launches of the mercury-atlas had been made with only a 50 percent success rate…
Over 52 years ago, in the early hours of May 5th, 1961 the US prepared to launch its first man into space. Three weeks earlier, the Soviet Union had sent Yuri Gagarin on an orbital mission. This was a suborbital mission planed to last only 15 minutes. For the moment that did not matter, the entire nation held its breath while Alan Shepard became America’s first man in space.
“Dear friends, you who are close to me, and you whom I do not know, fellow Russians, and people of all countries and all continents: in a few minutes a powerful space vehicle will carry me into the distant realm of space. What can I tell you in these last minutes before the launch? My whole life appears to me as one beautiful moment. All that I previously lived through and did, was lived through and done for the sake of this moment.” Yuri Gagarin prior to launch of Vostok 1.
When the 20 Cosmonaut candidates were asked to anonymously vote for which candidate they would like to see fly first, all but three chose Gagarin. The consensus was, Gagarin was very focused, and demanding of himself and others when necessary.
