The Large-Scale Electrochemistry and Possible Consequences of Deep   Impact Mission to Tempel 1
  Some consequences of hypervelocity impact onto the comet Tempel 1 nucleus are considered under assumption that SP comets are fragments of massive icy envelopes of Ganymede-like bodies saturated by products of ice electrolysis that underwent global explosions.
