Shi was the ninth human in space, but she was the first among women. 50 years ago, on June 16, 1963, Valentina Tereshkova in spaceship “Vostok-6” circled the Earth issuing in air of the entire phrase "I am Seagull! Everything goes well, onboard everything is all right".
One day prior to the Seagull start, on June 14, from Baikonur one more Soviet ship went to space "Vostok-5". It was piloted by Valery Bykovsky with a signal “Hawk”. Information that Bykovsky by his flight "insured" a going to the orbit of the spaceship of Valentina Tereshkova was secret. The start of the Bykovsky ship checked readiness of the Tereshkova rocket for flight into an orbit.

On July 5, 2013 the Russian Federation post issued a stamp devoted to the 50 anniversary of the first female space flight of cosmonaut V.Tereshkova.
On value is presented the postage stamp of the USSR issue of 1963 with the image of the first woman-cosmonaut and a flying seagull was the onboard signal of Tereshkova, thought up by Yuri Gagarin.
