Aviation Photo #1600718 NASA Ares 1 - NASA

The very first Ares 1 rocket, standing as tall as a 33-story skyscraper and 40 stories on top of the Mobile Launch Platform and Crawler Transporter, slowly emerges from the massive Vehicle Assembly Building as it rolls out to Launch Pad 39B for the first test flight, Ares 1-X, October 20 2009. If the program goes forward, Ares is the manned replacement for the shuttle and could take astronauts back to the moon eventually. Third tallest rocket in history it is just shy of the record 363-foot Saturn V.
