This made me smile, a lot.
I didn’t realize the entire launch pad was moved, not just the shuttle and engines! “Slow and Steady”, the Shuttle Crawls to Launch Pad:
Too bad this is it’s last mission, and the second to last (I believe) off all the USA space shuttles. *sigh* Sad. Because the new shuttle fleet won’t be ready for another 1-2 years (and hopefully not longer).
