The NASA Software Engineering and Software Assurance Electronic Handbook (SWEHB) is the agency’s authoritative, integrated source for software engineering and assurance requirements, rationale, guidance, lessons learned and objective evidence expectations. Built as a dynamic, wiki‑style site, SWEHB consolidates NPR 7150.2 NASA Software Engineering Requirements and NASA‑STD‑8739.8 Software Assurance and Software Safety Standard into a single, searchable location and preserves historical data across versions—making it straightforward for teams to plan, execute and verify compliance and to leverage generative AI for analysis and planning.

High-quality source code is the foundation of reliable, maintainable and secure software systems. For NASA missions, where safety, precision and reliability are non-negotiable, ensuring code quality is not just a best practice—it is an absolute imperative. Software isn't just "code that makes things work"; it forms the backbone of NASA's mission-critical systems—in spacecraft control, communications, scientific experiments and astronaut safety. Poor or defective code could result in catastrophic mission failures, compromised safety and significant financial and reputational consequences.

The recently released report Closing the Software Understanding Gap, published by the Cybersecurity and Infrastructure Security Agency (CISA), highlights the widening divide between the rapid pace at which modern software is developed and the much slower pace at which it can be rigorously understood, verified and assured. This gap presents major risks to national security and critical infrastructure and has direct relevance to NASA’s missions, systems and software assurance responsibilities.

Acting Chief of Safety and Mission Assurance (SMA) Nathan Vassberg’s 35-year career has shaped him into a leader who blends technical depth with a big‑picture view of risk, culture and mission success. His vision centers on continuing to promote SMA as a trusted, collaborative partner. To Vassberg, this means enabling smart, informed risk decisions; providing clear guidance through insight, oversight and surveillance; adapting to mission needs; and modernizing tools, policies and processes without compromising safety.

NASA is building a Space Microbial Culture Collection (SMCC), a culture repository to house a diverse collection of microbial isolates from space-related research and exploration efforts. SMCC will store, curate and make these valuable biological resources available to the public.

Over the past 10 years, the Office of Safety and Mission Assurance (OSMA) Pressure Systems program facilitated a broader use of the NASGRO^® software for analyzing and sustaining pressure systems. By expanding the capabilities of NASGRO to incorporate Fitness-For-Service of ground-based pressure systems, NASA centers can take advantage of access to perpetual, royalty-free NASGRO licenses that realize a significant cost savings in agencywide software expenses.

The NASA Safety Center Technology and Innovative Solutions Office (TISO) recently created a highly praised custom dashboard for Johnson Space Center’s institutional risk data.
