The extremely salty, very cold, and almost oxygen-free environment under the permafrost of Lost Hammer Spring in Canada's High Arctic is the one that most closely resembles certain areas on Mars.

If you want to learn more about the kinds of life forms that could once have existed - or may still exist - on Mars, this is a good place to look.

After much searching under extremely difficult conditions, McGill University researchers have found microbes that have never been identified before.

By using state-of-the-art genomic techniques, they have gained insight into their metabolisms.

In a recent paper in ISME, the scientists demonstrate, for the first time, that microbial communities found living in Canada's High Arctic, in conditions analogous to those on Mars, can survive by eating and breathing simple inorganic compounds of a kind that have been detected on Mars.

This discovery is so compelling that samples of the Lost Hammer surface sediments were selected by the European Space Agency to test the life detection capabilities of the instruments they plan to use on the next ExoMars Mission.

Developing a blueprint for life on Mars Lost Hammer Spring, in Nunavut in Canada's High Arctic, is one of the coldest and saltiest terrestrial springs discovered to date.

The water which travels up through 600 metres of permafrost to the surface is extremely salty, perennially at sub-zero temperatures and contains almost no oxygen Jun 07, 2022.

An international research team including the University of Gottingen has investigated the chances of survival of kombucha cultures under Mars-like conditions.

Kombucha is known as a drink, sometimes called tea fungus or mushroom tea, which is produced by fermenting sugared tea using kombucha cultures - a symbiotic culture of bacteria and yeast.
