It's epic, it's heart wrenching, it's an end of an era, enter other cliché here: __________________________.
It is, after all, the last flight of space shuttle Atlantis and the last flight of any space shuttle. Ever. If you're reading this over the weekend chances are you missed it, but that's OK because thanks to modern technology accelerated by the space program (CCD cameras and computers) you will be able to watch it easily on YouTube or NASA TV. Missing it means you don't really care that much about the U.S. government space program, possibly because you don't care for space in general. It is, after all, the final frontier and you (or the United States or the world) have a lot to get through before that becomes a priority. Alternatively you may be very busy helping usher the Commercial-Space era once the Space-Shuttle era comes to an end on July 8 (a much better proposition than the Soyuz era or the Russian-Space-Capitalism era or Who's-Laughing-Now-And-Who's-Paying-56-Million-Dollars-Per-Seat era).
