The basic design is very simple - it's based on the original Shuttle Program patch with a view "to the future" (ad futurus).
I thought it was important to remember where we came from - hence the use of the original program triangular patch - with an optimistic eye towards the future (the bright star), without paying any specific reference to the Moon, Mars, ISS, or Cx. This is a Shuttle patch, past and future, so I wanted to keep it simple.
