NASA Breakthrough in Multi-Layered Pressure Vessel NDE

2-minute read

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.

New Tool for Developing Safety Assurance Cases

5-minute read

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.

SMA Leadership Profile: Andrew Demo

7-minute read

“I am not the same, having seen the moon shine on the other side of the world,” said author Mary Anne Radmacher. For Ames Research Center’s newest Safety and Mission Assurance (SMA) Director Andrew “Drew” Demo, a lifetime of travel has taught him to appreciate diversity, exercise empathy and sensitivity, and build relationships — all essential building blocks to his leadership style.

Featured Safety Message


Risk Versus Risk Trades

As explorers and scientists, we at NASA have been making risk trades since the beginning. This safety message illustrates risk trades such as taking one risk versus another risk, as compared to taking a risk to gain a benefit. Which option seems to give the best opportunity to succeed? When decisions are time-critical and you have minutes or seconds to decide, the first workable option based upon experience (training and operations), skill, and systems knowledge can save the day.
