The well-known Tunguska-1908 phenomenon (TP) problems (the fast transfer ofthe kinetic energy of the meteoroid W~10-50 Mt TNT to air, with its heating toT>10^4 K at an altitude of 5-10 km, the final turn of the smoothly sloping,~0-20^o to horizon, trajectory of the body through ~10^o to the West, thepattern and area of the tree-fall and trees' scorching by heat radiation, etc.)allow a simple solution within the New Explosive Cosmogony (NEC) of minorbodies, as opposed to other approaches. The NEC considers the short-period (SP)comet nuclei, to which the Tunguska body belonged, to be fragments produced inexplosions of massive icy envelopes of Ganymede-type bodies saturated byproducts of bulk electrolysis of ices to the form of a 2H2+O2 solid solution.The nearly tangent entry into the Earth's atmosphere with V~20 km/s of such anucleus, ~200-500 m in size and ~(5-50)x10^12 g in mass, also saturated by2H2+O2, initiated detonation of its part of ~10^12 g at an altitude of 5-10 km.This resulted in deflection of this fraction trajectory by 5^o-10^o, and fastexpansion with ~2 km/s of its detonation products brought about their fastslowing down by the air, heating of the latter to T>10^4 K and a phenomenon ofhigh-altitude explosion. On crossing the Earth's atmosphere, the main part ofthe unexploded nucleus escaped into space, and this body moving presently in anSP orbit should eventually be identified in time. Its impact with W~250-3000 MtTNT on the Earth's surface (which could occur in 1908) would have produced acrater up to ~3.5-8 km in size, with an ejection of dust that would havebrought about a climatic catastrophe. The processes involved in the TP areresembling those accompanying falling P/Shoemaker-Levy 9 onto Jupiter and,possibly, the impact-caused Younger Dryas cooling ~13 ka ago.
