Today, the Cassini spacecraft is scheduled to make its closest approach ever to the Saturnian moon Enceladus. Flying to within 50 km of the surface, Cassini hopes to probe the chemical makeup of the geysers spewing from the south pole of Enceladus. Previous investigations indicate the high probability of an ocean beneath the crust of Enceladus, and this latest investigation will seek the tell-tale signs of chemistry that might indicate the presence of life.
