Mars salty lake organisms could be living under the ice-cap

Liquid water discovered on Mars

An exciting discovery of a liquid water lake on the red planet by a group of scientists of ESA (the European Space Agency) has recently been made public. The group working on the satellite called Mars Express has discovered the lake underneath the large southern polar ice-cap. This discovery opens up many new possibilities for us to search for Mars salty lake organisms. Therefore, scientists on Earth are thrilled by the new prospects.

Life finds a way  – even in extreme places on earth

We know organisms can be found in every corner of the Earth, also in places that are very extreme. These organisms are known as extremophiles, and biologists have found them on Earth in both boiling hot geysers as well as cold salty lakes underneath the polar ice-caps. The question is now; could similar organisms exist on Mars? In order to answer this, we first have to understand the what kinds of life could live there.

 Ancient Mars was earth’s fraternal twin

We know that geological evidence tells us of the young Mars as a planet not too different from Earth. However, because Mars is smaller than Earth it could not keep its atmosphere until the present day. Another problem for the habitability of Mars is that it does not have a proper magnetosphere protecting the surface from radiation. Mars today looks very different; we have lost the oceans and all we have left of the atmosphere is carbon dioxide. We could, therefore, suspect the lake found on Mars to contain organisms from this ancient ocean.

Scientists could Find Mars salty Lake organisms in the future

Now, we still have many unanswered questions about this amazing discovery. Even though Mars is very far away, the answers are within our reach. Therefore, we are going to need new and dedicated scientists, who can study these far-off potential homes for life in the future.
