Yuri Gagarin

Yuri Gagarin was a 20th century Soviet cosmonaut who became, as far as the majority of humanity was aware, the first human being to journey into outer space circa 1960. (TV: The Seeds of Death, AUDIO: 1963: The Space Race)

In 1903, after receiving a wealth of information from the future, Grigori Rasputin foresaw, among other things, Gagarin's achievement. (AUDIO: The Wanderer)

Before travelling to the Moon aboard a Soviet lunar capsule in November 1963, the Sixth Doctor told Peri Brown that he was far more qualified for space travel than Gagarin. (AUDIO: 1963: The Space Race)

The Seventh Doctor, Ace, Markus Creevy and Lt Raina Kerenskaya saw both Gagarin and Valentina Tereshkova, the first woman in space, on a podium in Red Square, Moscow, in the Soviet Union at a ceremony marking the fiftieth anniversary of the October Revolution on 7 November 1967. (AUDIO: Thin Ice)

In an attempt to take over the Earth, the Monks contaminated people's memories to make it look as if they had been there since the beginning. One moment they used was of Gargarin about to take off in a spaceship to explore outer space. (TV: The Lie of the Land)
