There is still liquid water on Mars: scientists believe that at least one lake is hidden on the planet

New study suggests that under the icy surface of Mars there may be reservoirs of liquid water at the South Pole.
Scientists from different universities in the UK have presented their new study, in which they claim that there is liquid water under the southern ice cap of the planet. Although this environment is most likely unsuitable for sustaining life, Mars may have had the right conditions in the past, writes the Daily Mail.
Mars scan data from spacecraft has repeatedly hinted that there may be reservoirs of liquid water under the ice cap at the South Pole of Mars. There are ice sheets on Mars and at the South and North Poles. In terms of volume, they are comparable to the size of the Greenland ice sheet. Some studies suggest that, as on Earth, lakes of liquid water may exist under the thickness of this ice. Although other scientists argue that the water there cannot be in a liquid state, if it exists there, it is only in the form of ice, given that the temperature in winter at the poles of Mars can drop to -364 degrees Celsius.
Focus already wrote that American scientists, for example, in their new study, stated that there is no water under the surface of ice on Mars and presented their justifications.
But scientists from different universities in the UK presented their study in which they prove the presence of liquid water under the ice cap at the South Pole of Mars. As part of their scientific work, scientists used measurements of the shape of the surface of the ice cap using spacecraft instruments to detect patterns there in its height. Then they created computer models to find out what might affect the change in the height of the ice sheet.
The study showed that the ice cap on Mars has in some parts deviations in height and this can be explained by the presence of subglacial lakes with liquid water, just like on Earth. They once again compared the simulation data and the readings of the instruments of the spacecraft, and they almost coincided. Thus, scientists believe that water in a liquid state under the ice on Mars still exists. According to scientists, it does not freeze due to the continued geothermal activity on the Red Planet, which allows it to maintain warmer temperatures below the surface of the ice sheet.
“Subglacial lakes exist on Mars, but this does not necessarily mean that there is life there now. This water is too salty even for microbes. But it is possible that in the past there were living organisms on Mars when the planet's climate was different, “says Francis Butcher from the University of Sheffield.
According to Neil Arnold from the University of Cambridge, the results of the study show a very high probability of the existence of reservoirs of liquid water under the ice cap at the South Pole of Mars, although there may be few such lakes, or maybe even one.
As Focus already wrote, the Webb Space Telescope recently took images of Mars.
As for space telescopes, then , as Focus, already wrote, NASA is planning a joint mission with SpaceX to the Hubble telescope, within which the space observatory, which is already 32 years old, can be upgraded.
