NASA 'Worm' Logo Embroidered Patch #2
The third official NASA insignia is a modern, simplistic emblem. The emblem is rectangular with approximate dimensions of 1.5 inches high by four inches long with square corners. It features a white background with flame red continuous script lettering which simply reads "NASA". This emblem has been replaced with the NASA vector design as the official logo.
The NASA logo (worm) has been retired from official use since 1992.
