Mission Failure – Root Cause
In NASA nomenclature a root cause is:
Along a chain of events leading to a mishap, the first causal action or failure to act that could have been controlled by policy/practice/procedure
Root Cause – failure to use metric system in ground software files used in trajectory models

Mission Failure – Contributing Causes
In NASA nomenclature a contributing cause is:
A factor, event or circumstance which led directly or indirectly to the dominant root cause or which contributed to the severity of the mishap
