The team convened in January after Boeing\u2019s Orbital Flight Test on Dec. 20 missed its objective to dock with the International Space Station (ISS) because a necessary orbital burn did not happen after there was an anomaly with the mission elapsed timer.&nbsp;<\/p>\n<p>NASA said the team found the two critical software defects were not detected ahead of flight despite multiple safeguards, and ground intervention prevented loss of vehicle in both cases. Breakdowns in the design and code phase inserted the original defects, and breakdowns in the test and verification phase failed to identify the defects preflight despite their detectability. These errors could have led to risk of spacecraft loss had the NASA-Boeing team not been able to correct them.<\/p>\n<p>NASA said there was no simple cause of the two software defects making it into flight, and there were numerous instances where the Boeing software quality processes either should have or could have uncovered the defects. These issue require systemic corrective actions and the team has outlined 11 corrective actions. The team is still performing additional analysis as to why the anomalies occurred. NASA also said that the intermittent communications issues still are under investigation. The Agency also said that it cannot definitively share the root causes and full set of corrective actions needed for the Starliner system, but expects to have those results at the end of February.&nbsp;<\/p>\n<p>\u201cWe want to make sure we have a comprehensive understanding of what happened so that we can fully explain the root causes and better assess future work that will be needed. Most critically, we want to assure that these necessary steps are completely understood prior to determining the plan for future flights,\u201d NASA said in a release.&nbsp;<\/p>\n<p>In addition, NASA is also planning an Organizational Safety Assessment of Boeing\u2019s work on the Commercial Crew Program, to examine \u201cworkplace culture.\u201d This review would be added to the company\u2019s Commercial Crew Transportation Capability contract. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Boeing, NASA, and U.S. Army personnel work around the Boeing CST-100 Starliner spacecraft after it landed on Dec. 22, 2019.
