Scientists have discovered a way to grow a cyanobacteria known as blue-green algae that claims to help humans live on the Red Planet known as Mars. Cyanobacteria are tiny living things that release oxygen during photosynthesis, a process organisms use sunlight to make their own food and they are found in water.
The blue-green algae can transform to other gases such as nitrogen, carbon dioxide and substances or nutrients that help living things to grow. Scientists think that what made Earth's atmosphere breathable 2.4 billion years ago is a huge rise in the numbers of cyanobacteria.
The atmosphere of Mars consists majorly of carbon dioxide and nitrogen and researchers believes that the presence of blue-green algae on Mars can be used to allow plants grow for food and medicine but it is impossible to grow blue-green algae naturally except through a special bioreactor known as Atmos which was developed by a team of scientists from the University of Bremen, Germany.
Using Atmos which is a machine for growing microbes, scientists have shown that cyanobacteria could be grown using resources found on Mars and can help other organisms such as bacteria and not only blue-green algae to grow.
Although, Atmos is still a test version! There are strong indications that results can inspire a system that could one day support life on Mars.
