Researchers in Spain have developed a vacuum chamber that can recreate most of the physical conditions found on Mars. The researchers also included a system that allows them to douse instruments with Martian dust directly, to see how they hold up while in use. In my view, the main problem for devices on Mars is the dust, which covers all the instrumentation and therefore decreases their average lifespan, said Jose Angel Martin-Gago, a physicist at the University of Madrid and lead author of the study, in an email to The Verge. Once thats done, the scientists can begin testing small electromechanical instruments measuring up to eight inches.
