ESA's Rosetta orbiter is preparing to make a daring 6 km (3.7 miles) pass of one of Comet 67P/Churyumov-Gerasimenko's most active regions - an area on the comet's larger lobe designated as Imhotep. As the comet moves closer to the Sun, mission controllers are expecting to see an exponential increase in volatile activity, and ESA hopes that the new orbits planned for the little probe will allow scientists to gain a better understanding of these effects...
