Terrestrial craters give us an excellent opportunity of direct analisys as opposed to craters out of the E arth. However, on the Earth there are only few sites where traces of strong impacts event could be studied in the fi eld. The traces of ancient impacts are better preserved in the frozen subsoil at subpolar latitudes. One of such sites is Popigai crater, located in subpolar Siberia, Russia, presumably caused by a giant impactor 35 Ma ago. This astrobleme gives a good chance to observe in situ the asteroid crater, impact materials and other consequenses of great energy deposition. T he crater was thoroughly studied during last few decades due to impact diamond inventories associated with it [1]. However a number of problems remain unresolved and wait for further studies: the physics and chemistry of impactites and impact breccias; mineral components with metamorphic rocks affected by great shock and impactites; material ejecta; structural forms invoked by crater formation; problems of remote sensing studies and problems related to comparative planetology. In the framework o f Europlanet program, we plan the expedition to Popigai site scheduled to 2012.
