Crown Prince Felipe received Monday the first human to walk in space, Russian cosmonaut Alexei Leonov, currently on a visit to Spain.

Their meeting took place at the Zarzuela Palace on the outskirts of Madrid and was attended by the Russian ambassador to Spain, Alexander Kuznetsov, the royal household said on its Web site.

Leonov, 77, made his space walk in 1965 after he was selected as one of the 20 pilots of the Soviet air force to form the first group of cosmonauts.

The prince and the space traveler recalled that historic moment during the Voskhod 2 space mission when Leonov was outside the spacecraft for a little more than 12 minutes.

He is the only surviving member of the five-man crew of the Voshkod 2.

In 1975, Leonov took part in another historic milestone in the conquest of space when the U.S. space vessel Apollo 18 docked with Russia's Soyuz 19.

The cosmonaut likewise mentioned his artistic side and how he carried into outer space a set of colored pencils and paper, with which he sketched the Earth and drew likenesses of the Apollo 18 astronauts.

His historic flight occurred four years after Soviet cosmonaut Yuri Gagarin made the first human space flight on April 12, 1961.

The 50th anniversary of Gagarin's flight was the subject of a series of conferences held on Spain's Canary Islands last week, in which Leonov took part.

Also attending the conferences was Apollo 11 commander Neil Armstrong, who on July 1, 1969, became the first person to set foot on the moon.
