Water on Mars: Mystery Deepens around Dozens of Underground Lakes on Red Planet

News 18  

Mars is the closest planet that man-made technology ventured to explore life beyond Earth. About three years ago scientists confirmed that the dusty, dry red ball that is Mars, has lakes filled with liquid water. Researchers from NASA’s Jet Propulsion Laboratory examined the data from the European Space Agency’s Mars Express orbiter and observed dozens of radar reflections similar to the discovery made in 2018. Study co-author and NASA JPL investigator Jeffrey Plaut, in a statement, said, “’We’re not certain whether these signals are liquid water or not, but they appear to be much more widespread than what the original paper found.” He added that liquid water could be common beneath Mars’ south pole or these radar signals are suggestive of something else. The study carries forward the findings from 2018 when signals from a radar device reflected off Mars’ south pole appeared to show a liquid subsurface lake.
