Rosetta and a Rocky Asteroid 500,000 km Away from Us (Now)

Awesome is the only word to describe Rosetta's journey to an asteroid 500,000 kilometers away. (Rosetta is, to use old-fashioned locution, a rocket-ship.) Apart from the thought of a remote speck in the solar system, think of the astounding inferential ability it took to make Rosetta pass within 2,000 miles of the asteroid that is imaginatively pictured above. (The photo images, we are told, will come later. They have to be processed.) Who was it that said that inference is just a shell game, entirely a matter of subjective conceptual prejudice? Ask such folks to explain how Rosetta got to where it did -- and is managing to send back pictures to earth.

The choice of "Rosetta" as the name of the rocket-ship was inspired -- even though it is not yet clear that Rosetta will unlock a significant amount of basic information about our universe. But who really cares? Ah, the romance of it all!
