The Mars Express locates three new bodies of water below the South Pole of Mardon. Using new radar data from ESA’s Mars Express spacecraft, researchers have detected three reservoirs of liquid water trapped under the red planet’s southern polar cap.

To establish the range of subclass waters in the region, colleagues from Universiti deli Studio Roma Trey and Drs. Elena Pettinelli analyzed the new data collected on the Mars Express for the Radar Advisor and Ionosphere Sounding (MARSIS) team on Mars Advanced.
The researchers said that “Mars was getting hotter and wetter with water on the surface, flowing like Earth.”
“Although today it is not possible for the water to remain stable on the surface, the new result opens the possibility that an entire system of ancient lakes could be underground, perhaps millions or billions of years old.”
“They would be an ideal place to find evidence of life on Mars, even if it is very difficult to get there.”

“They alter unique ecosystems, providing useful metaphors for astronomers to explore how life can live in extreme environments.”
Similar to the techniques used in the investigation of subglacial lakes in Antarctica, Canada, and Greenland, Drs. Patinelli and her co-authors explore three new underground water bodies.
The largest deposit measures approximately 20 x 30 km (12.4 x 18.6 miles) and is surrounded by many smaller bodies. Water is considered too salty to remain liquid at low temperatures.
“Our results reinforce the claim of the identification of a liquid water body in ultimi scoopuli and indicate the presence of other nearby wetlands,” the scientists said.
“We suggest that the waters are hypersaline perchlorate brine, which is known to form in the Martian polar regions and is believed to survive for extended periods at temperatures below the eutectic on the geologic scale.” The study was published in the journal Nature Astronomy.
Scientists have found a group of three lakes of salty liquid water on Mars, about six miles below each planet’s south pole ice sheet.
An international team examined radar data from MARSIS, a science instrument on the European Space Agency’s Mars Express spacecraft.
The technique uses radio wave bursting to image buried geological formations – similarly “seismic prospecting”, which helps predict earthquakes.
They found luminous lakes, which have the ability to sustain microbial life in extreme conditions, in the ultimi scoopuli, a region near the South Pole of the Red Planet.
Microbial life in lakes can include extrophils, which can withstand intense heat, extremely acidic environments, extreme pressures, and extreme cold.
The new discovery is the first ‘alien’ water to be found on the red planet since 2018, when the lake was first discovered beneath the Martian south pole ice sheet.
The 2018 discovery was the first evidence of liquid water on Mars that still exists today – an environmental scientist says it is ideal for the growth of microorganisms.
Scientists say that new lakes in the same area are indicative of the “presence of other surrounding wetlands.”
