Bacteria could help feed astronauts on future Mars missions

A team of astrobiologists at the University of Bremen’s Center of Applied Space Technology (ZARM) has grown cyanobacterium at low pressure using only Martian materials, demonstrating future astronauts could grow their own food and other resources on the Red Planet.
When the first astronauts land on Mars, it won’t be a short visit. Given the state of space propulsion technology and the rigid rules of celestial mechanics, a Mars mission means a very long wait until Earth and Mars are in the right position for the return trip. This is a major hurdle because taking along enough supplie
