“…This analysis focused on the abort risks and assumed that a failure requiring an abort had already occurred. As a result, several physical phenomena surfaced as the primary risk drivers related to the interaction between the crew module (CM) and booster during an abort [15]. A description of the risks is included in the following discussion of the top events.…”

A study was performed to assess the effect of booster configuration on the ascent abort process. A generic abort event sequence was created and booster related risk drivers were identified. Three model boosters were considered in light of the risk drivers: a solid rocket motor configuration, a side mount combination solid and liquid configuration, and a stacked liquid configuration. The primary risk drivers included explosive fireball, overpressure, and fragment effects and booster-crew module re-contact. Risk drivers that were not specifically booster dependent were not addressed. The solid rocket configuration had the most benign influence on an abort while the side mount architecture provided the most challenging abort environment.

High-end computing (HEC) plays a major role in the modeling and simulation needs of NASA missions. Two years ago, NASA was on the verge of dramatically increasing its HEC capability and capacity. With the 10,240-processor supercomputer, Columbia, now in production impact within the Agency and extending to partner institutions. Ad simulations in space exploration, shuttle operations, Earth sciences, and fundamental aeronautics research are occurring on Columbia, demonstrating its ability to accelerate NASA's exploration vision. This talk describes how the integrated production environment fostered at the NASA Advanced Supercomputing WAS) facility at Ames Research Center is accelerating scientific discovery, achieving parametric analyses of multiple scenarios, and enhancing safety for NASA missions. We focus on Columbia's impact on two key engineering and science disciplines: Aerospace, and Climate. We also discuss future mission challenges and plans for NASA's next-generation HEC environment.

This paper describes the quantitative application of the theory of System Health Management and its operational subset, Fault Management, to the selection of abort triggers for a human-rated launch vehicle, the United States' National Aeronautics and Space Administration's (NASA) Space Launch System (SLS). The results demonstrate the efficacy of the theory to assess the effectiveness of candidate failure detection and response mechanisms to protect humans from time-critical and severe hazards. The quantitative method was successfully used on the SLS to aid selection of its suite of abort triggers.
