Operational Modal Analysis of the Artemis I Dynamic Rollout Test

Operational modal analysis (OMA) techniques have been used to identify the modal characteristics of the Artemis I launch vehicle during the Dynamic Rollout Test (DRT) and Wet Dress Rehearsal (WDR) configuration prior to launch. Forces induced during rollout and on the launch pad are not directly measurable, thus necessitating a unique approach.

Looking Back, Moving Forward

Interview with NESC Director, Tim Wilson Upon reaching its 20th year of operations at NASA in 2023, the NESC is busier than it has ever been. With a portfolio of more than 160 in-progress requests from Agency programs, NESC Director Tim Wilson spends much of his day prioritizing, allocating funds from the organization’s fixed budget […]

Most Impactful NESC Assessments

After reflecting on the more than 1,200 assessments completed by the NESC over the last 20 years, Director Tim Wilson selected these assessments as his top three. They were selected because they would likely have the greatest and most lasting impact on human life and the furtherance of the NESC mission. He shared why their […]

23-07: Best Practices for Fabrication of Microelectronic Devices

The NESC has released a technical bulletin for the Avionics community. Material degradation during the fabrication of microelectronic devices has plagued the space industry for many years owing to the layering of many dissimilar metals to create these devices.

NESC Technical Bulletin 23-06:Considerations for Software Fault Prevention and Tolerance

The NESC has released a technical bulletin for the Software Engineering community. Mission or safety-critical spaceflight systems should be developed to both reduce the likelihood of software faults pre-flight and to detect/mitigate the effects of software errors should they occur in-flight.
