Space shuttle flight.

This is a link to live coverage of the flight. You should take a second to reflect on the bravery of these men and women. They are about to adventure to an area most only dream about, without a true understanding, but still dream. They will conquer the mighty atmosphere to make repairs and deliver supplies to the space station. They will depend on machinery they have no control over. They will walk into space, protected only by a suit. They will further the knowledge of mankind. Don't get me wrong, they will probably not invent a new element, but still our reach, as a species, will get a little longer today. I would hope that we can put aside our attitude of, "what does it do for me this second", to see the big picture, and remember our dreams from when we were little...they did.
