Whitepaper #250 submitted to the Planetary Science and Astrobiology Decadal Survey 2023-2032. Topics: habitability and water; life and prebiotic organics; Mars
The Martian subsurface is one of the most promising places on Mars for life to still exist today. Despite this, we have yet to send a dedicated mission to investigate the modern-day subsurface habitability of Mars or to search for signs of extant subsurface life. A spectacular scientific opportunity awaits!
