[[Yuri Alekseyevich Gagarin]] ([[Russian language|Russian]]: Юрий Алексеевич Гагарин; [[March 9]], [[1934]] – [[March 27]], [[1968]]), was a [[Soviet Union|Soviet]] [[cosmonaut]] who in [[1961]] became the first human to travel into space, as well as orbit the Earth.
'''Sergei Konstantinovich Krikalev''' (Сергей Константинович Крикалёв, born [[August 27]] [[1958]]) is a [[Russia]]n [[cosmonaut]] and veteran of six space flights. He has been dubbed by many “the last [[Soviet Union|Soviet]] Citizen” as in 1991–1992 he spent 311 days, 20 hours and 1 minute aboard the [[Mir]] space station whilst back on Earth the [[Soviet Union]] collapsed.
Krikalev was born in [[Leningrad]] (now [[Saint Petersburg|St. Petersburg]]), [[Russia]]. He is married to Yelena Yuryevna Terekhina and has one daughter, Olga Sergeevna Krikaleva, born in 1990. Sergei enjoys swimming, skiing, cycling, aerobatic flying, and [[amateur radio]] operations, particularly from space (callsigns U5MIR and X75M1K).
Yuri Gagarin was born in [[Klushino]] near [[Gzhatsk]], a region west of Moscow, Russia, on March 9, 1934 (the town would be renamed Gagarin in 1968 to honour Yuri), and his parents worked on a collective farm.
He overtook [[Sergei Avdeyev]]'s previous record for the career total time spent in space (747.59 days) during [[Expedition 11]] to the [[International Space Station]]. Krikalev has logged a total 803 days and 9 hours and 39 minutes in space.
After starting an apprenticeship in a metalworks as a foundryman, Gagarin was selected for further training at a high technical school in [[Saratov]]. While there, he joined the "AeroClub", and learned to fly a light aircraft, a hobby that began to take up an increasing proportion of his time. After completing his technical schooling, he entered military flight training at the Orenburg Pilot's School. While there he met Valentina Goryacheva, whom he married in [[1957]], after gaining his pilot's wings in a [[MiG-15]]. After graduating, he was posted at an airbase in the [[Murmansk]] region, near the [[Norway|Norwegian border]]
On [[April 12]], [[1961]], Gagarin became the first human to travel into [[outer space|space]] in ''Vostok 3KA-2'' ([[Vostok 1]]). His call sign in this flight was [[Siberian Pine|Cedar]] ([[Russian language|Russian]]: Кедр). After the flight, Gagarin became an instant, worldwide celebrity, touring widely to promote the Soviet achievement. On [[March 27]], [[1968]] he was killed in a crash of a [[MiG-15]] UTI on a routine training flight near [[Kirzhach]] together with his instructor. It is uncertain what caused the crash, but a [[1986]] inquest suggests that the turbulence from a [[Su-11]] interceptor airplane using its [[Afterburner (engine)|afterburner]]s may have caused Gagarin's plane to go out of control.
