Mars' advanced radar for the underground and ionospheric sounding instrument, or MARSIS, was the instrument used to detect evidence of the existence of liquid water on Mars. The device collected data between May 2012 and December 2015 and sent signals across the surface and polar cap Mars, measuring how the radio waves reflected towards the Mars Express. According to the collected sampling, there is a lake about 1.6 kilometers deep and measuring about 20 kilometers in length, news to CNN .
"This is only a small area of study: it is" said Robert Orosei, the study coordinator.
This is the first time that evidence of the The existence of stable water plans on Mars have been found, although this theory has already been formulated 31 years ago, like the masses of water that are found in the Antarctic zone here on Earth. , these masses on Mars may also contain salts or other minerals that can serve as important indicators for understanding the climate on Mars.
Nathaniel Putzig, head of the Mars SHARAD Orbiter Reconnaissance Mission, reveals that "we can not see the same reflection with SHARAD, even when we have recently gathered thousands of observations to create 3D views of both shells", questioning the results obtained by MARSIS 19659005]
