Hoy hace 50 años que el hombre llegó al espacio. El artífice de esta conquista fue el cosmonauta ruso Yuri Gagarin y hoy toda Rusia celebra su mayor hazaña aeroespacial. El pasado fin de semana publicamos en el diario un interesante artículo sobre esta conquista espacial titulado "Queremos tanto a Yuri" y hoy en la bítacora La Pizarra de Yuri nos presentan un completísimo post hablando del futuro de la conquista del espacio. Yo os dejo esta selección de imágenes de archivo llegadas por el servicio de las agencias de Yuri y su hazaña.

It was the Soviet Union's own giant leap for mankind _ one that would spur a humiliated America to race for the moon. It happened on Tuesday, April 12, 1961 when the air force pilot became the first human in space. (AP Photo/TASS)

TO GO WITH AFP STORY BY NICOLAS MILETITCH (FILES) This file photo taken on  April 12, 1961 shows Soviet Vostok-1 spaceship with cosmonaut Yuri Gagarin on board  blasts off on top of Rocket R-7 for the first manned trip into space from the  Baikonur Cosmodrome in Kazakhstan. The 27-year-old's 108-minute flight on April 12, 1961 is still remembered in Russia even after the USSR's collapse as its greatest national achievement. The first flight into space made by Russia, by Gagarin, allowed the Soviet leadership, fully entrenched in the cold war, to maintain the superiority of the communist system over thier principal adversary, the United States.

MIA01. WASHINGTON, DC (EE.UU.), 07/04/2011.- Imagen cedida hoy, jueves 7 de abril de 2011, de la portada del periódico estadounidense The Huntsville Times (miércoles 12 de abril de 1961) que registra la hazaña del cosmonauta ruso Yuri Gagarin. Cincuenta años después del vuelo tripulado que marcó el comienzo de la conquista del espacio, el mito y la leyenda aún envuelven la figura de Gagarin. Fue el primer ser humano en ver con sus propios ojos la redondez de la Tierra en toda su plenitud y los 108 minutos que duró su vuelo en torno al planeta marcaron un hito en la historia y le convirtieron en el hombre más famoso del mundo, en todo un héroe, también amplificado mil veces por la propaganda soviética.
