In July 2018, an international team of scientists discovered that Mars was. Using data obtained from the Mars Express orbiter
Orosei's team suggested that the salt, which lowered the melting point of ice, could be present at such concentration that they allowed the lake to form.
This new study builds on that research but posits the liquid water underneath the ice
Using a number of physical models, the team tried to understand the level of heat that would need to be generated in order to form the proposed underground lake. Their paper, published in the Geophysical Research Letters on Tuesday, showed that a plausible solution would be if a magma chamber was present at a depth of no more than 10 kilometers below
. conditions for liquid water to form. Thus, the paper concludes that "recent magmatism may offer a plausible explanation," but without such activity, suggest that there may be no liquid water at the ice cap at all
The team suggests that NASA's InSight lander,will provide a clearer picture of how hot the Martian crust might get. Mars's interior is not as hot as Earth's, but we're not sure exactly how warm it is.
Of course, if there is liquid water then does that mean there may also be life? An underground lake provides a potential Garden of Eden, a safe paradise where life can still, uh, find a way
"We think that if there is any life, it probably has to be protected in the underground from radiation, "said Ali Bramson, an author on the new paper.
On Feb. 13,which had been studying the planet from the ground for 15 years. In that time, Opportunity rather than dusty and dry
And, sadly, Opportunity is dead, Mars may well be more alive than we thought. ]
