Gallium Nitride (GaN), a Wide Bandgap (WBG) semiconductor, is emerging as a promising material for electronic components in the aerospace industry. While historically semiconductor devices have been silicon-based, in recent years, devices using WBG materials such as silicon carbide and GaN have matured to a point where their performance and economic value are competitive with, or in some cases, exceed traditional silicon parts.

As part of the Software Assurance Research Program (SARP), the project team leading the “Software Assurance Tasking Checklists for NASA-STD-8739.8” project developed and deployed a tool to automate the identification of Software Assurance (SA) activities using Commercial Off-The-Shelf tools. This checklist tool is one of five research projects in Fiscal Year 2020 sponsored by SARP and aimed to address the current needs of the SA community across the agency.

As the new calendar year approaches, the Human Factors Task Force (HFTF) started reflecting on its many achievements over the past 12 months. The team gained new members, offered and developed more training, and integrated Human Factors into the agency mishap reporting system.

Sometimes, being on the outside provides perspective. That’s the case for Rick Nybakken, director for Safety and Mission Assurance (SMA) at the Jet Propulsion Laboratory (JPL).

“My career path has really helped to shape me: I’ve been at JPL for 35 years, and I’ve probably been in SMA for eight of those years,” explained Nybakken. “Working with Safety and Mission Assurance as a partner helped me understand the value since day one. That contributed to my desire to eventually work in SMA and gain a greater understanding from the inside.” 

The Office of Safety and Mission Assurance’s Multi-Layered Pressure Vessel Risk Mitigation Project (MLPVRMP) made significant advancements in detecting weld flaws in Multi-Layered Pressure Vessels (MLVP) through the use of advanced techniques in Nondestructive Evaluation (NDE). The unique design and fabrication of MLPVs made inspection of inner weld areas joining shell to shell layers impossible, until now. This breakthrough presents the agency with the ability to thoroughly examine and baseline in-service MLPVs for critical weld flaws, thereby supporting selective MLPV replacement based on verified risk. 

NASA projects go through the full life cycle, from concept to implementation to closeout, with a number of reviews along the way. These reviews ensure that the developed project can meet mission objectives and do so safely. The project must make a case for itself: show and explain why the system will work as intended. Enter, the safety assurance case, or simply safety case as it may be more commonly known. Researchers at Ames Research Center have been fine tuning their notion of the safety case and developing a tool to make its development easier.

The U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA) recently released “Notice of Extension of Enforcement Discretion Regarding Cylinders That Have Exceeded Their Periodic Requalification Test Date.” 

In recent years, the Office of Safety and Mission Assurance (OSMA) Pressure Systems program accomplished a number of efforts to facilitate broader use of NASGRO for the analysis and sustainment of pressure systems. By expanding the use of NASA’s perpetual, royalty-free NASGRO license, centers across the agency will realize a significant cost savings.
