To commemorate the 50 Year of the first manned flight into space the Moldavian Post is issuing a set of four stamps depicting the most famous astronauts ever - Yuri Gagarin, Alan Shepard, Virgil Grissom and German Titov.
Yuri Alekseyevich Gagarin (9 March 1934 - 27 March 1968) was a Soviet pilot and cosmonaut. He was the first human to journey into outer space when his Vostok spacecraft completed an orbit of the Earth on April 12, 1961. Gagarin became an international celebrity, and was awarded many medals and honors, including Hero of the Soviet Union.
Alan Bartlett Shepard, Jr. (November 18, 1923 - July 21, 1998) was an American naval aviator and astronaut who became the second person, and the first American, in space. Ten years later, he commanded the Apollo 14 mission, and was the fifth person to walk on the Moon.
Virgil Ivan Grissom (April 3, 1926 - January 27, 1967), better known as Gus Grissom, was one of the original NASA Project Mercury astronauts and a United States Air Force pilot. He was the second American to fly in space and the first person to fly in space twice.
