An open resource for the space radiation effects engineering community.
Space RHA exists to make radiation hardness assurance knowledge and tools more accessible. The space radiation effects community has decades of hard-won expertise, but much of it is locked behind institutional walls, proprietary reports, and expensive software tools.
We're building a set of free, open engineering tools and an active community forum where RHA engineers can share knowledge, ask questions, and help each other solve real problems — whether they're planning their first beam test or leading an RHA program for a flagship mission.
Space RHA's tools and community span the full scope of radiation hardness assurance: Single Event Effects testing and analysis, total ionizing dose characterization, displacement damage assessment, parts evaluation, and mission-level risk management.
Our SEE Cross-Section Fitting Tool, NIEL Conversion Tool, and Parts Radiation Advisor are designed by working engineers to solve the practical problems that come up every day in RHA work.
Space RHA is a community effort. If you have test data to share, ideas for new tools, or want to help improve existing resources, we'd love to hear from you. The best RHA knowledge comes from practitioners working real problems — and this site is built to make that knowledge more accessible to everyone.
Join the conversation on our forum or get in touch to contribute.
All tools are free to use, no login required. We believe RHA knowledge should be accessible to everyone building hardware for space.
Join a growing community of radiation effects engineers sharing knowledge, test data, and practical experience through our open forum.
Every tool and resource is designed by working RHA engineers who understand the real-world problems you're trying to solve.
