Soviet cosmonaut Alexei Leonov, who became the first person in history to spacewalk in 1965, has died aged 85.
Tethered to a spaceship by a 4.8m (16ft) cable, the Russian floated above Earth for 12 minutes.
“You just can’t comprehend it. Only out there can you feel the greatness – the huge size of all that surrounds us,” Leonov told the BBC in 2014.
But the outing nearly ended in disaster as his spacesuit inflated and he struggled to get back in the spaceship.
At a time when the US and the USSR were jostling for space supremacy, Leonov’s mission was lauded as a triumph at home.
But Leonov’s ambitions did not stop at his spacewalk. He went on to become the commander of Soyuz-Apollo, the first ever joint US-Soviet mission in 1975.
Leonov died at Moscow’s Burdenko hospital on Friday after a long illness, his assistant confirmed.
Russian cosmonaut Oleg Kononenko said Leonov’s death was a “loss for the whole planet”, while President Vladimir Putin said he admired the astronaut’s courage.
