Life on Mars

Cyanobacteria could thrive excellently even under the inhospitable conditions on Mars, produce oxygen and thus enable astronauts to survive self-sufficiently in the future. This is the conclusion reached by Humboldt Fellow Cyprien Verseux from the Center for Applied Space Technology and Microgravity (ZARM) at the University of Bremen. He and his team now present some of their findings in the scientific journal "Frontiers in Microbiology".
Cyanobacteria are known primarily as blue-green algae, which can proliferate in lakes in summer, the scientists explain. On Mars, their full potential comes into play, as they produce oxygen through photosynthesis. This ability is found in almost all plants, but cyanobacteria can also grow on the basis of the nutrients that are present on Mars

Mars won't be too crowded. French Professor Jean-Marc Salotti (Bordeaux Institut Nationwide Polytechnique) found that a small community of 110 people is sufficient to set up a self-sustaining colony on Mars. The settlers would live in an oxygen-filled glass dome where they would have to focus on building an agricultural industry to provide for themselves.
