FHA, PSSA and SSA Fault Tree Analysis (FTA) and Failure Modes and Effects Analysis (FMEA): they are common methods in both aviation and space. Damage Modes and Effects Analysis (DMEA): it reveals damage modes and their domino effects to guide the design and operations ! it is equivalent to the Zonal Safety Analysis (ZSA) in ARP4761. This analysis is usually supported by a Common Cause Analysis (CCA), which is used to find and eliminate or mitigate common causes for multiple failures. For Critical Items Lists (CIL): the Failure Mode and Effects Analysis (FMEA) is performed to identify failure modes. As part of this process, critical failure modes that could lead to loss of life or loss of mission are also identified. These critical failure modes are then placed into a CIL, which is carefully examined for programmatic control by implementing inspection requirements, test requirements and/ or special design features or changes, which would minimize the failure modes occurrence [20] ! the control of these critical failure modes is monitored via a Particular Risk Analysis in ARP4761. For Probabilistic Risk Assessment (PRA): this is a scenario-based probabilistic risk analysis. Quite generally, a scenario is prevented through prevention of all of its MCSs, and each MCS is prevented through prevention of any of its elements. The role of the PRA in the context is to quantify each risk/ MCS, by taking into account the individual risks/ MCS that surface during the program/ project [5] ! this risk assessment enables to define particular probabilistic safety requirements when quantitative risk assessment is deemed necessary (e.g. without sufficient experience based engineering data) and is equivalent to a Particular Risk Analysis in ARP4761.

The transportation capabilities for human-rating Space Exploration missions are emerging. Safety is a major argument on which the agencies commit to ensure to crew a safe journey and return to Earth. Secure the mission success requires a regulated Safety assessment process. Space Safety regulations and standards already exist in agencies and instit...
