NASA Worm Logo Embroidered Patch #3 

This version in black and yellow/orange is representative of the NASA log patch worn by the astronauts. It is approximately 4"  x 1.5" . The third official NASA insignia is a modern, simplistic emblem. The emblem is rectangular with continuous script lettering which simply reads "NASA". Unofficially, it has become known as the NASA "Worm". This emblem has been replaced with the NASA vector design as the official logo.
