Cassini Space Probe to buzz Saturn's moon tomorrow

Sometimes, you just need to take a step back and let yourself be blown away by some of the advancements humanity has made over the past few decades. For example, the Cassini Space Probe, an unmanned craft flying out near Saturn, is going to fly within 30 miles of the moon of Enceladus tomorrow, nearly crashing into the icy object in order to study it better.

The goal of the fly-by is to study the composition of the moon's gigantic geysers to see if there's a vast ocean of water buried under the surface. Flying a satellite so close to the surface from so far away is a huge feat, one that, if successful, will go down as one of the most complicated maneuvers NASA has pulled off. Amazing.
