The letter indicates that the intermediate numbering system applies, and e.g. After the Challenger disaster, a sequential numbering system was restored, with the number according to counting from the beginning, although, unlike the initial system, the assignment of numbers is based on the initial schedule and may not reflect launch order. These codes were assigned when the launches were initially scheduled and were not changed as missions were delayed or rescheduled. Beginning in 1984, each mission was assigned a code, such as STS-41-B, with the first digit indicating the last digit of the federal fiscal year, the second digit indicating the launch site (1 was Kennedy Space Center and 2 was Vandenberg Air Force Base, although Vandenberg was never used), and the letter indicating scheduling sequence. Initially, the launches were given sequential numbers indicating order of launch, such as STS-9. Specific shuttle missions are therefore designated with the prefix STS.
