The NASA Radiation Hardness Assurance (RHA) Process Standard

This paper presents status on the upcoming NASA Agency-level RHA Process Standard. Based on recommendations provided by the NASA Engineering and Safety Center (NESC), the NASA Electronic Parts and Packaging (NEPP) Program has led development of an agency-level standard for space flight avionics and electronics RHA. The standard introduces a novel RHA taxonomy and prescribes the process required by NASA programs and projects to baseline their RHA programs consistent with the MEAL (Mission, Environment, Application, and Lifetime) criteria including the risk tolerance posture. The standard also provides requirements for the RHA schedule integration in the program or project lifecycle and requirements for data deliverables content. Additional non-prescriptive technical content is provided in the standard appendices to guide development of RHA programs for NASA missions.

Solid State Drive Radiation Assurance With Active Testing

Single-event effects (SEE) and total ionizing dose (TID) data are presented for several automotive- and industrial-grade solid-state drives, and the effects of different active test configurations on hardness assurance are explored.

Avionics Radiation Hardness Assurance (RHA) Guidelines

Based on the need to develop and adopt timely and up-to-date guidance to ensure that natural space radiation environment threats do not compromise mission success, the NASA Engineering and Safety Center (NESC) was solicited to develop and publish guidance for deriving radiation hardness assurance (RHA) requirements and for evaluating avionics hardware elements with respect to total ionizing dose, total non-ionizing dose, and single event effects. This document contains the outcome of the NESC assessment.
