According to Reuters.com, NASA's Ares 1-X rocket -- the proposed successor to the space shuttle, and a scaled down version of the rocket that could return the U.S. to the moon -- is being rolled out to its launch pad. It's scheduled to be launched on October 27th and you can be sure I'll be near a computer to watch a live stream on that day. I can still remember Columbia's maiden launch, and if this rocket (and its descendants) really do return us to the Moon, the asteroids and Mars, then this launch could be every bit as monumental.
I should note that I'm not personally in favor of a renewed moon program; given the end game of reaching Mars, it seems to me that deep space missions to near-Earth asteroids are a better use of resources (especially given how asteroids and comets have a nasty history of actually hitting the Earth, where as the Moon is ever-so-slowly getting further away from us). Sinking trillions into a moon won't bring us any closer to Mars, and it certainly won't help with the deep space experience we need to actually get to Mars.
Regardless of its initial destination, I'm sure that the launch is going to be one hell of an impressive display ... and there's no way I'm missing it.
