SARP Sponsors Nine Research Initiatives
January 18, 2018
Researchers wrapped up nine NASA Software Assurance Research Program-sponsored research projects aimed to benefit Software Assurance processes across the agency and presented the results to the Software Assurance Working Group (SAWG). After select proposed initiatives were chosen in 2016, researchers were given a year to develop, analyze, test, record findings and present results to the SAWG. Two of the projects were multi-year studies that continued from the prior year.
ESD Wireless Wrist Straps: The Shocking Truth
January 10, 2018
It is essential that NASA engineers use proper precautions when working with Electrostatic Discharge (ESD) sensitive hardware, as poor ESD control practices could be the difference between success and failure for a mission. ESD control is a fundamental component of NASA’s workmanship policy, which is why NASA requires operators to verify ESD personnel grounding systems (e.g. wrist or heel straps that are continuously connected to common point ground) are properly functioning before they enter an ESD Protected Area (EPA) or come within one meter of an ESD sensitive item.
RHA Methodology Helps Improve Mission Duration Timelines
January 02, 2018
A new Radiation Hardness Assurance (RHA) methodology could lead to shorter, but more frequent missions at NASA. Mike Xapsos, a research physicist in the Radiation Effects and Analysis Group and member of the NASA Electronic Parts and Packaging Program (NEPP) at NASA Goddard Space Flight Center, has developed an improved method for evaluating the performance of a microelectronic device in space, which closes the gap between design specifications and on-orbit performance.
SMA Partners With Pathfinder Study to Support MBSE Direction
January 02, 2018
“At NASA, we should allow computers to do what computers are good at, so people can do what people are good at.”
This perspective, explained by MBSE Pathfinder Study Co-Lead Jessica Knizhnik, is the main motive behind a Pathfinder study, sponsored by the NASA Engineering and Safety Center, to investigate how Model-Based Systems Engineering (MBSE) and Model-Based Engineering (MBE) techniques can be applied by NASA projects.
