A significant recommendation to NASA from the 2019 NAS Study entitled “An Astrobiology Strategy for the Search for Life in the Universe” is that:

“NASA’s programs and missions should reflect a dedicated focus on research and
exploration of subsurface habitability in light of recent advances demonstrating the breadth and diversity of life in Earth’s subsurface, the history and nature of subsurface fluids on Mars, and potential habitats for life on ocean worlds.”

As such, the committee also identified key questions that will need to be addressed in the next decade of astrobiology research:
• How does subsurface life adapt to extreme environments and energetic spectra?
• How do marine and continental subsurface terrestrial communities inform what chemosynthetic or rock-hosted communities on other worlds might look like?
• What is the spatial and temporal distribution of potentially habitable environments on Mars, especially in the subsurface?
• What are the chemical inventories and physical processes sustaining rock-hosted life on ocean worlds?

The goal of this NAI Workshop Without Walls is to develop community recommendations for future missions and exploration strategies for subsurface life on Mars. We intend to address these key questions to ensure that research and exploration of subsurface environments with a focus on life is a well-represented objective in the next decadal survey. The deliverables of this activity will be a series of white papers that will be presented to the community, and then submitted to the decadal committee.
