Besides the usual elements of the mission number and the crew's names, I also included an outline of a space shuttle orbiter as a major element to honor this program as a memorial by listing all the names of the space shuttles, and including the years of service starting with the roll out of the Enterprise in 1976 and ending with the last year of 2010. Moreover, I included two of the major elements of the space shuttle program: the Hubble telescope and the International Space Station. And since the NASA Space Shuttle program is an American space program, I used a palate of mostly red, white, and blue.
