RHA Methodology Helps Improve Mission Duration Timelines
January 02, 2018
3-minute read
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.
