Over 200 scientists from 25 nations are conducting simulation tests in the vast sandy terrain of Dhofar Desert in southern Oman for a manned mission to Mars. Scientists from across the world sent ideas for experiments and the mission, named AMADEE-18, quickly grew to 16 scientific experiments, such as testing a “tumbleweed” whip-fast robot rover and a new space suit called Aouda. The cutting-edge spacesuit, weighing about 50 kilograms, is called a “personal spaceship” because one can breathe, eat and do hard science inside it. The suit’s visor displays maps, communications, and sensor data. A blue piece of foam in front of the chin can be used to wipe your nose and mouth.
