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.

Colonize and live on Mars thanks to cyanobacteria?

Colonize and live on Mars thanks to cyanobacteria? Research has shown that cyanobacteria can reproduce excellently under Martian conditions and thus form the basis for biological life support systems. 17 February 2021 © ZARM/Universität Bremen A trip to Mars takes about nine months with current spacecraft. That means astronauts would have to spend a long time on the Red Planet after landing. Supplying them there with life-sustaining consumables is not easy, however, because in addition to the long travel time, safety aspects and transportation costs also figure into the equation. In other words, resources must be both created and recycled on Mars. Biological systems, or bioregenerative life support systems (BLSS), would be the best solution. More specifically, cyanobacteria could be the solution. Humboldt Fellow Cyprien Verseux from ZARM at the University of Bremen, Germany, has now published initial research results in the scientific publication frontiers which indicate that c
