The results of a large study will make you smile when you think of your descendants: scientists have discovered many large bodies of water below Mars’ South Pole; They cheerfully assert that this is supporting evidence for previous research that suggested that beneath the surface of the Red Planet were large saltwater lakes. Here and there on Mars, there may also be wet areas that we haven’t been to.
This discovery is both important for the quest for extraterrestrial life, since life, as we all know, needs liquid water to survive. In addition, locating lakes will help us be more careful in future Mars missions, avoiding bringing life on Earth to Mars.
The new discovery is made possible by the advanced MARSIS – Mars Radar engine that uses sound to observe the subsurface and ionosphere, located on ESA’s Mars Express ship. Mars Express is still in orbit around Mars right now.
The ice is located at the south pole of Mars.
In 2018, also using the MARSIS tool, the ESA team announced the discovery of a large lake below Mars, calling it a new breakthrough in the search for alien life. However, experts expressed skepticism, claiming that the ESA team has not collected enough data to confirm the nature of the water body, nor is it certain that it is the water body.
In the new study led by expert Elena Pettinelli, a team of scientists analyzed the data collected by MARSIS and accurately determined: below the surface of Mars is a large mass of solution. Besides, they also discovered many smaller water bodies, clearly separated from the large water mass by patches of arid soil.
“Not only did we detect the position, magnitude and intensity of radar response data in the 2018 study, but also identified three additional areas. [nước ngầm] new”Said Professor Pettinelli.
“The main lake is surrounded by smaller water bodies, but because of radar technology and the distance between the satellite and the surface, we cannot confirm whether the water bodies are linked.“.
When will it become the second home of humanity?
Based on the MARSIS data obtained, the team identified lake water as a salty solution, with a large salt energy likely to keep the water liquid under the low temperature conditions of Mars’ south pole. .
The fact that many lakes are concentrated in one place may also make sense, that the formation of the lake is not difficult, and the history of Mars may have seen many different versions of saltwater lakes. If so, life on Mars would most likely have found a way to exist today, since the time of Mars was more livable than it is now.
The new research has been published in the journal Nature Astronomy.
