The European Space Agency has revealed that the comet - 67P/Churyumov-Gerasimenko "is not nearly as soft and fluffy as it was believed to be".

The first results to emerge from the team of the SESAME experiment (Surface Electrical, Seismic and Acoustic Monitoring Experiment) confirm that "the strength of the ice found under a layer of dust on the first landing site is surprisingly high".

"The mechanical properties of 67P will be derived. SESAME's two other instruments suggest that cometary activity at this landing site is low, as well as revealing the presence of a large amount of water ice under the lander," Klaus Seidensticker from the DLR Institute of Planetary Research said.
