♦ This research is of great significance to the success of future MARS missions.
♦ The endurance of these microorganisms was tested by researchers from NASA and the German Aerospace Center.
♦ They were tested by launching them into the stratosphere, which represents some of the key conditions for the Red Planet.
♦ By using scientific balloons to transport experimental equipment to the stratosphere, new methods of exposing bacteria and fungi under Martian-like conditions have been tested.
♦ During the journey, some microorganisms, especially black mold spores, can survive even when exposed to high ultraviolet rays.
