Russia celebrates Gagarin\'s conquest of space

The Soviet Vostok-1 spaceship with cosmonaut Yuri Gagarin on board blasts off April 12, 1961 Russia on Tuesday marked a half century since Yuri Gagarin became the first man in space, the greatest victory of Soviet science which

expanded human horizons and is still remembered by Russians as their finest hour.At 0907 Moscow time on April 12, 1961 Gagarin uttered the famous words "Let's Go" as the Vostok rocket, with him squeezed into a tiny capsule at the top, blasted off from the south of the Soviet republic of Kazakhstan.After a voyage lasting just 108 minutes that granted the 27-year-old carpenter's son historical immortality, Gagarin ejected from his capsule and parachuted down into a field in the Saratov region of central Russia.From that moment on, his life, and the course of modern space exploration, would never be the same again."This was one of the greatest events of the 20th century," said the head of Russia's space agency Anatoly Perminov. "His flight opened a new page in the development of humankind."Russian President Dmitry Medvedev on Tuesday praised Gagarin's space flight as a watershed that ushered in a new era of space exploration."I believe it was a truly revolutionary event," Medvedev said in an interview with Chinese television, a transcript of which was published by the Kremlin."It was an outstanding achievement of Soviet space exploration, which divided the world into the time before and the time after the flight, which became the space era"  adding that Russia's space exploration had changed its focus from the first romantic days of space travel and now focused on practical results of its missions.

The Soviet Union scored its greatest propaganda victory over the United States, spurring its Cold War foe to eventually retake the lead in the space race by putting men on the moon in 1969.

Although Russia will this year take full responsibility for taking astronauts to the ISS when the shuttles are retired, its space programme has seen its share of problems in the run-up to the anniversary.Three navigation satellites crashed into the ocean after launch, the latest launch for the ISS was delayed by a week due to a technical problem and the government has already said that Perminov is on the way out.As well as the heroism of Gagarin, Russia is also remembering the genius of the man who created the rocket that put him into space and masterminded the flight -- chief Soviet rocket engineer Sergei Korolev. One of the most remarkable figures in the history of space travel, Korolev survived being sent to the Gulag under Stalin to become a figure of such importance his role was only disclosed after his death in 1966.The anniversary has also prompted a release of information from Russia about the most mysterious aspects of Gagarin's life, most notably his still unsolved death in a plane crash in 1968.Declassified documents released last week said his jet likely manoeuvred sharply to avoid a weather balloon, prompting it to crash in a region outside Moscow and killing Gagarin and instructor Vladimir Seryogin.The Soviet Vostok-1 spaceship lies at the landing site 700 km south-east of Moscow after the first manned space tripFormer Soviet space workers have also recalled how all those involved in the flight were forced by the Soviet Union to lie for years that he had landed in his capsule and not by parachute as was the case in reality.This was because they feared the orbit would not be counted as valid by the international organisation monitoring spaceflight.Gagarin's flight was also a step into the unknown loaded with risk and he endured particularly uncomfortable moments during re-entry when his craft started spinning out of control."If we had thought then about calculating the reliability of the ship according to modern norms, we would never have sent a man up," Boris Chertok, 99, a rocket engineer who worked with Gagarin, said on Monday.
