My patch represents the following:

The large stars represent the 14 crew members lost.
Small stars represent the 50 states.
The Space Station and Hubble are depicted to represent 2 of the major shuttle program objectives Several other small satellites could also be added.
The 3 smaller shuttles represent 3 operational phases, launch, on orbit and landing. A 4th could be added to represent ground processing.
