NASA: Shuttle Fleet's Safe Return to Flight Is Key to Space Station Progress

Since its inception, the International Space Station has experienced numerous problems that have resulted in significant cost growth and assembly schedule slippages. Following the Columbia accident and the subsequent grounding of the shuttle fleet in February 2003, concerns about the future of the space station escalated, as the fleet has been key to the station's assembly and operations. In August 2003, the Columbia Accident Investigation Board drew a causal link between aggressive space station goals--supported by the National Aeronautics and Space Administration's (NASA) current culture--and the accident. Specifically, the Board reported that, in addition to technical failures, Columbia's safety was compromised in part by internal pressures to meet an ambitious launch schedule to achieve certain space station milestones. This testimony discusses the implications of the shuttle fleet's grounding on the space station's schedule and cost, and on the program's partner funding and agreements--findings we reported on in September 2003. The testimony also proposes a framework for providing NASA and the Congress with a means to bring about and assess needed cultural changes across the agency.
