Summary

Recent findings from the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) suggest the presence of liquid water beneath the southern polar ice cap on Mars, which could have significant implications for the planet's habitability. However, the current cold and dry conditions on Mars make the existence of liquid water seem less probable, according to Phys.org.
