Tests of the Shuttle tires with the Convair 990 LSRA began in April 1993 at NASA’s Dryden Flight Research Center at Edwards Air Force Base in California. Its job was to test the brakes, landing gear systems, nose wheel steering control, and overall durability of the Space Shuttle’s tires. NASA 810 was modified into a landing systems research aircraft or LSRA. To test the Shuttle tires, NASA roped in an old medium-altitude atmospheric testing aircraft, a modified Convair 990 Coronado narrow-body airliner with the tail number NASA 810. The pressure inside the Michelin-brand tires was 340 psi (23.9 kg per square centimeter). Each tire, of which there were six, could support over 64 metric tons. The Space Shuttle’s tires weren’t just any tires having to go to space and back meant that they had to be tough. In 1993, it was the humble tire that came under the knife. Every system and component was trialed and tested to its breaking point to see if it could be improved. Like all spacecraft, the Shuttles were upgraded throughout their lives. The Space Shuttles very much formed the backbone of NASA’s space operations. National Aeronautics and Space Administration’s (NASA) four Space Shuttles, Columbia, Challenger, Discovery, and Atlantis, as well as a fifth, Endeavour, which made its inaugural flight less than a year earlier, held between them over 50 completed missions.
