White Papers for the Next Decadal Survey: Thermal Protection Systems and InstrumentationNASA is anticipated to commission the next Planetary Science Decadal Survey (PSDS) with preparation expected in early calendar year 2020. The new PSDS will outline the priorities of science missions for the decade spanning 2023-2032. For the previous PSDS, the science and technology communities have been invited to submit white papers to the PSDS sub-panels as background information to guide the PSDS recommendations. The National Research Council has previously stated that white papers that represent the opinion of many authors from different institutions carried more significant and weight, and the recommendations from the previous PSDS attempted to reflect more of a consensus opinion.In 2009, a total of 4 white papers were submitted to the PSDS panels regarding thermal protection system (TPS) readiness for missions, as well as one on TPS instrumentation. The TPS readiness papers were co-authored by 90 individuals from many institutions. These white papers surveyed the TPS materials for both forebody and afterbody of a probe and analyzed the suitability of materials for missions to each destination. In addition, each paper outlined the ground testing required and ongoing technology development. Recommendations were provided for further technology development and ground test capability in order to fulfill future missions. Planning for the next PSDS: Many improvements and changes have occurred in the past 10 years with regard to TPS materials and instrumentation. New materials have been developed and tested, such as the high density material Heatshield for Extreme Entry Environment Technology (HEEET), and new capabilities for ground testing for high heating and high pressures have been added such as the 3” nozzle at the Ames arc jet. NASA has also flown several TPS instrumentation suites, such as MEDLI and EFT-1.In order to provide the PSDS sub-panels with the most current information about the state-of-the-art suit-ability for TPS materials for entry missions, we are be-ginning to update and draft new white papers. We will present the outline for material to be covered in the white papers, and we invite all IPPW attendees to parti-ciate in co-authoring these papers.
