Mars Express finds more subsurface ponds of liquid water on Mars:
ESA's Mars Express orbiter has found evidence of more liquid water beneath the ice cap in the south polar region of Mars. Based on data from the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) radar instrument, researchers found three new subsurface ponds, with the largest measuring 20 x 30 km (12 x 19 mi).
In 2018, the Mars Express team discovered that the Martian ice caps are not ice throughout, but actually have large, subsurface lakes of liquid water. Using the MARSIS instrument to probe beneath the southern polar cap from May 2012 and December 2015, the orbiter mapped out a lake 20 km (12.4 mi) wide under 1.5 km (0.9 mi) of solid ice. Now, more ponds are being revealed at the same depth by a reanalysis of the same data.
The ponds could serve as habitat for extremophiles.
