Summary:
 Quakes and meteor impacts on Mars generate seismic waves that can help map the interior.
 A new study analyzed seismic waves detected by the Insight lander and concludes that 11-20 kilometers beneath the surface,
 a zone of pores and fractures is filled with liquid water -
 more than was thought to fill Mars' surface oceans before they disappeared 3 billion years ago.
 Though too deep to drill, the reservoir is a possible refuge for life.
