| Popis: | International audience; To celebrate and appropriately illustrate the rendezvous of the European Rosetta spacecraft with comet 67P/Churyumov– Gerasimenko and the landing of Philae on the surface of the comet’s nucleus on 12 November 2014, the French science museum Palais de la Découverte developed and presented a new and original demonstration. The experiment simulates the behaviour of a cometary surface in a vacuum and shows the formation of jet-like features. We explain here how to prepare an analogue to cometary material from porous ices and carbon, how to approximately reproduce the cometary environment at low pressure, temperature and solar illumination, and how to present the experiment at a public science demonstration. |
