Twenty years ago, a space mission to land a probe on a comet was envisioned. And now, ten years and 6 billion kms after, the Rosetta mission have seen success.
It's undoubtedly a resounding accomplishment for European Space Agency (ESA) which launched the Rosetta mission in March 2004. After blasting off from Kourou spaceport of French Guiana, Rosetta and Philae have logged at least 6 billion kms just to reach the comet.
For a time, the spacecraft had gone on standby for almost 3 years. Apparently, it had gone 500 million miles away from the sun that the solar panels can't absorb enough energy to recharge and keep things going. Fortunately, the Rosetta came out of its hibernation just this January and approached its target: comet 67P/Churyumov-Gerasimenko.
The comet, discovered in 1969, orbits the sun at the speed of 135,000 km/h. Measuring 4-km wide, the comet's shape is similar to that of a rubber duck which initially left people doubting if a landing would be possible at all. (This is because if the Philae lander touched down on uneven surface, it could turn over the wrong side -- and has no way to right itself up.)
