Two former American astronauts have met up with two Russian veteran cosmonauts in Moscow – to mark the 35th anniversary of East meet West, in space.
The American Apollo spaceship first docked with the Soviet Soyuz craft in July, 1975.
The group met up again in Moscow’s Space Museum, to open an exhibition about their historic encounter.
They shared memories of their first meeting in space, which took place at the height of the Cold War.
For two decades, the US and USSR had been competitors in the space race.
The join up was the pinnacle of four years of planning between the two Cold War adversaries.
