This paper seeks to inform of the need for, and approaches to, sustaining critical thermal protection systems (TPS) for in-situ planetary missions in the coming decade. The key technologies, HEEET and PICA, are needed only for these NASA missions, wi

The conformal ablative TPS first developed under NASA's Hypersonics Project in the early 2000's demonstrated very low through the thickness conductivity compared to state-ofthe- art PICA. However, in initial arcjet testing of Conformal-1, surface rec

For this study, HfB2-based ultra high temperature ceramic (UHTC) samples were prepared by hot pressing and field-assisted sintering (FAS) with 10–20 vol.% SiC (baseline), 5 vol.% TaSi2, and 5 vol.% iridium. Dense billets were tested for hardness an
