Heading To The Comet

Space probe performs Mars fly-by:

"A European space probe has completed a close fly-by of the planet Mars in a crucial manoeuvre on its 10-year journey to land on a distant comet.

The unmanned Rosetta craft passed within some 250 km (150 miles) of Mars.

In a precise move, the probe used the planet's gravity to change course on its voyage to the Churyumov-Gerasimenko comet out near Jupiter."
