TPS and Entry System Technologies for Future Mars and Titan Exploration

The purpose of this white paper is to provide an overview to the NRC Decadal Survey Mars and Ocean Worlds Sub-Panels on thermal protection system (TPS) technologies required for future Mars and Titan exploration missions. It considers the capability of heritage TPS technology used by previous Mars and Titan missions. A prime conclusion is that there are important advances regarding the availability of forebody TPS therefore, we recommend that NASA invest in a cross-cutting technology program that focuses on development and sustainment of relevant TPS materials, entry systems, test facilities, design tools, and flight instrumentation.

TPS and Entry Systems Technologies for Future Mars and Titan Exploration

During the past twenty years, NASA effectively erased earlier Mars mishaps with six successful missions to the Red Planet. These missions delivered one orbiter and five payloads to the surface. Those payloads included three rovers, Spirit (2004) which roamed 11 years, Opportunity (2004) which roamed nearly 15 years, and Curiosity (2012) which is in its ninth year, along with two landers, Phoenix (2008) and InSIGHT (2018). In July, the Mars 2020 mission will send another large rover, Perseverance, which will land in 2021. The InSIGHT mission even demonstrated the capability to send CubeSats along to help with communication back to the surface. NASA has demonstrated the capability to land a metric ton of vehicles plus science instruments on Mars and expects that the same technologies will be equally successful landing Dragonfly on Titan in the 2030’s. The thermal protection systems (TPS) used on the Mars missions are sufficiently developed and matured to continue furthering science on both Mars and Titan, assuming that the TPS materials are sustained by industry. The purpose of this white paper is to encourage further exploration and science on both Mars and Titan because we have the technologies to support them. In addition, we will look forward to human exploration of Mars and identify the improvements in TPS materials required to facilitate landing the larger payloads.
