Recent mission studies point to delivery of the probe either at Uranus or at Neptune will require 3-D Woven TPS, either the two layer HEEET or the single layer 3MDCP. Recent studies point to 3MDCP being more mass efficient. The 3MDCP capability being developed to support MSR EES is sufficient if the probe size is 1.25 m or less. If the prove diameter is larger than 1.25 m, a possibility then Dual layer HEEET which is scalable is at TRL 6 is certified and ready. It is possible to develop a seam approach that would allow 3MDCP and the mass savings could warrant development of a seam capability. Depending on the outcome of the planned Flagship mission study that Ames plans to support, Ames is already working on a concept that can be developed and demonstrated in the coming years. If in case Aerocapture is demonstrated through a Earth Flight Test and becomes part of the mission design for Uranus, this makes delivery of the probes from orbit easier. Whether the probe is to delivered from Orbit or not, still 3-D Woven (HEEET or 3MDCP) is the only TPS qualified to enable the Ice Giant in situ probes.
