The four shuttles all facing opposite of one another depict a parting of ways for the next generation of spacecraft and the new direction in which we are headed...to the moon, mars, & beyond. The 14 stars within the red & blue stripes are in honor of the astronauts lost during the shuttle program. The 29 is for the years of service. The star of the astronauts symbol over the single star of the flag represents all of the people from across this "Great Nation" that worked as one to achieve the goals that made this program a success. The black silhouettes of the Challenger & Columbia are to remind us that tragedy can sometimes come with success, and we must strive in dedicating ourselves to the utmost safety in all that we do.
