With the downing of flight MH17, tensions between Russia and the U.S over Ukraine are at a new high. Sanctions have been put in place, targeting Russia's finance, defence and energy sectors. Russia has found a way to hit back; America's space industry is its target. When Neil Armstrong set foot on the lunar surface in 1969, it was the pivotal point in a space race that had lasted for more than a decade.
America had beaten the Soviets to the Moon. It was a great moment of US national pride, but the two rivals soon realised they could achieve so much more by working together. "I had no idea when I joined Nasa, wanting to be an astronaut, hoping to fly, that I would have anything to do with Russia," says Mike Foale, the British-born Nasa astronaut.
