  4. Rosetta calls in on Earth flyby

    Date de publication:

    3 Mars 2005

    One year after launch from Kourou, French Guiana, the Rosetta probe will be just 2,000 km from Earth at the end of this week. So long to cover such a short distance? In fact, the probe is returning to our neighbourhood, having already completed one orbital revolution of the Sun. This first flyby close to Earth will boost Rosetta’s chase toward its target comet Churyumov-Gerasimenko.
