The Rosetta space probe reached the comet 67P/Churyumov-Gerasimenko almost a month ago but remained at a distance from it of not less than 52 kilometers (about 32 miles). ESA’s scientists spent the last few weeks studying the comet, also to determine the route to follow for the probe and the Philae lander. Today, Rosetta is scheduled to start the series of maneuvers that in a few days will bring it at a distance of approximately 29 km (about 18 miles) from the comet to arrive later about 10 km (a bit more than 6 miles) from it.
