Liquid ‘Water’ Bodies Found Under Mars Surface

The European Space Agency (ESA)’s Mars mission Mars Express has discovered several liquid bodies under the south pole of the red planet using its Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) instrument. The findings give fuel to previous studies that have suggested at the presence water on Mars. The ESA mission has found a large liquid body, separated from other smaller liquid bodies by dry patches. The MARSIS instrument on ESA’s Mars Express spacecraft functions by sending radar pulses that can penetrate the surface and ice caps of Mars.

Now, this is not the first time such a discovery has been made. In 2018, researchers used the same MARSIS instrument had announced that they have found a vast lake beneath the surface of Mars. However, that study was questioned by experts who express doubts over the nature of the liquid body. In other words, they weren’t sure if scientists have enough details to prove if its a water body.
