I watched the news on BBC. They are right now in an orbit 100 km away from the comet and getting pictures of 2.5 mt resolution. In the next few weeks they will reach upto 30 km orbit and take more high resolution pics. The head of the mission mentioned about boulder like structures on the comet, origins of which is not knows. The comet also has vast plain areas, suitable for landing a probe. It will be by November when we get detailed results of the chemical composition of the comet.
