The surface of Mars has been a subject of repeated exploration, from both in orbit and in situ. But this exploration is only skin-deep, and a growing community of scientists are calling on NASA to explore the Mars underground. Charity Phillips-Lander joins Jake to talk about this exciting world underground and how she thinks we might have a chance to learn about it with a mission concept called MACIE.
