Arc Jet Testing of 3D Mid-Density Carbon Phenolic (3MDCP) for Mars Sample Return
When accounting for the highest-heating trajectory with margin, dispersion, and greatest system mass, MSR-EES is predicted to experience the highest heat flux and pressure (approximately 3300 W/cm2 hot-wall, 200 kPa) of any earth entry vehicle todate. To verify performance requirements are met by the forebody TPS, the material must be tested to validate model predictions and give confidence to stakeholder’s expectation of performance. 3D Mid-Density Carbon Phenolic (3MDCP) is NASA’s baseline material for the forebody heatshield of the MSR-EES. As part of the arc jet campaign to evaluate material performance, recent testing has completed in the Interaction Heating Facility (IHF) using a new facility setting to achieve the necessary environments.

An Overview of Combined CFD and Material Response Simulations of Arcjet Experiments in Support of the Mars Sample Return Earth Entry System
This presentation will also include a top-level overview of the CFD/material response arcjet simulation process. A discussion will be made on the best-practices for running CFD solutions of arcjet experiments including how to determine the inflow conditions for the CFD solution from the arc heater settings. The required inputs to the material response solver will be presented, as well as a discussion of how they can be extracted from the CFD solution. Grid requirements for both the CFD and material response solver will be explored.

Fe-Phosphates in the Jezero Crater Fan: Implications for Habitability and Sample Return
In the ~1000 sols since the Mars 2020 Perseverance rover landed on the floor of Jezero crater, it has traversed >23 km, carrying out analyses of the crater floor and western fan. The fan is comprised of sediments transported and deposited by streams that once flowed into Jezero crater in the late Noachian to early Hesperian[1]. Detailed investigation of the sediments and rocks of the western fan can thus provide insights into ancient fluvial to lacustrine environments on Mars, whether they were habitable, and/or if biosignatures maybe preserved.
