How the European Space Agency stunned the world

The story behind the Euro-quango whose Rosetta mission finally puts Nasa in the shade.

Formative years

Its roots date back to the 'Sputnik shock' of the late 1950s, but the European Space Agency didn't actually come into being until 1975. Nasa had already sent 24 men to the moon and Russia's epic Salyut space station programme was in full swing, so what did ESA choose for its inaugural mission? A worthy but entirely dull unmanned orbiting probe called Cos-B.

Its thunder was stolen again in the 1980s. ESA had developed the simple, cheap and effective Ariane rocket for launching satellite payloads, whereas Nasa came up with the complex, expensive, unreliable but super-glamorous Space Shuttle. They both did the same job, but only one came with astronauts, space walks and all the media-friendly jeopardy of re-entry.

Recent history

But – who would have guessed? – it turned out ESA was right. We all know what happened to the Shuttle, whereas Ariane 5 rockets still blast off regularly from their launchsite in French Guiana. On 2 March 2004, one of them hurled the then little-known robot probe Rosetta on its way, the start of an astonishingly bold 10- year-long, four-billion-mile mission to hitch a ride on a comet, a five-kilometre-long lump of ice and rock with almost no gravity, hurtling through space at 34,000 miles an hour. Like trying to land a bullet on a howitzer shell that's still in flight.
