NASA Space Shuttle Insignia Modified

The NASA Space Shuttle Flight Insignia that I modified by replacing the center element of the shuttle without the external fuel tank and rocket boosters, in addition I place the Earth beneath the shuttle and last, I replaced the current NASA "meatball" with I modified version that I created a while ago.

In the futuer, I plan on doing customized Space Shuttle Insignias for the fleet by doing some re-colorization and replacing Space Shuttle at the bottom with specific shuttle designations as follows:

OV-098 - Space Shuttle Pathfinder, (a mockup in Huntsville, AL)
OV-099 - Space Shuttle Challenger
OV-100 - Space Shuttle Explorer, (a mockup in Houston, TX)
OV-101 - Space Shuttle Enterprise
OV-102 - Space Shuttle Columbia
OV-103 - Space Shuttle Discovery
OV-104 - Space Shuttle Atlantis
OV-105 - Space Shuttle Endeavour
