Cyanobacterial Growth Optimized for Mars Promises Lifeline to Crewed Missions

Cyanobacterial Growth Optimized for Mars Promises Lifeline to Crewed Missions Crewed mission to Mars February 19, 2021 Share In keeping with humanity’s quest to explore new worlds and boldly go where no one has gone before, leading space agencies are gearing up to send crewed missions to Mars. One of the many challenges of this mission is the production of food and other life-support consumables on site without having to import them from Earth. In a new study, scientists at the Center of Applied Space Technology and Microgravity (ZARM), at the University of Bremen, in Germany, showed that it is possible to grow Anabaena cyanobacteria under conditions that are a compromise between conditions on the Martian surface and optimal conditions for cyanobacterial productivity.

New Method for Growing Cyanobacteria in Mars-Like Conditions

New Method for Growing Cyanobacteria in Mars-Like Conditions Scientists show for the first time that Anabaena cyanobacteria can be grown with only local gases, water, and other nutrients and at low pressure February 17, 2021 NASA, in collaboration with other leading space agencies, aims to send its first human missions to Mars in the early 2030s, while companies like SpaceX may do so even earlier. Astronauts on Mars will need oxygen, water, food, and other consumables. These will need to be sourced from Mars, because importing them from Earth would be impractical in the long term. In Frontiers in Microbiology, scientists show for the first time that Anabaena cyanobacteria can be grown with only local gases, water, and other nutrients and at low pressure. This makes it much easier to develop sustainable biological life support systems.

Bacteria bioreactor could make food and medicine for people on Mars

Bacteria bioreactor could make food and medicine for people on Mars Adam Smith © Provided by The Independent Scientists are developing bacteria that can be grown with only the local gases, water, and nutrients found on Mars, to make life on the Red Planet feasible. All species of the bacteria anabaena cyanobacteria can be used to produce oxygen through photosynthesis, while others can turn atmospheric nitrogen into nutrients on Earth. However, the challenge is that these bacteria cannot grow directly on Mars; the atmospheric pressure is less than one per cent of Earth’s, which is too low for liquid water, and the level of nitrogen gas is too low for the bacteria’s metabolism.
