Launch site payload test configurations for Space Shuttle scientificpayloads

This paper provides an overview of the test configurations which are utilized in prelaunch testing at the John F. Kennedy Space Center (KSC) for those scientific payloads which are flown in the National Space Transportation System (NSTS) Space Shuttle. A generalized view of the payload prelaunch processing is provided and the major types of payload configurations are described. The majority of the prelaunch test activity involves the verification of experiment functions, compatibility of experiment-to-carrier interfaces and payload-to-orbiter interfaces. The Shuttle's avionics system is presented as it relates to payloads. The testing of Spacelab experiments and the experiment-to-Spacelab compatibility verification is described as is the test activity for partial payloads and their experiments. Test operations which involve simulated orbiter interface verification and actual payload-to-orbiter testing are discussed. An overview of the Space Station payload processing concept is presented.
