The Materials Adherence Experiment (MAE) was a material science experiment conducted during NASA's Mars Pathfinder mission. It consisted of a small module mounted to ''Pathfinder's'' rover ''Sojourner'' that examined the effects of Martian surface dust on solar cells.〔 〕 ==Purpose== Using solar power on the Martian surface is challenging because the Martian atmosphere has a significant amount of dust suspended in it.〔 In addition to blocking sunlight from reaching Mars's surface, dust particles gradually settle out of the air and onto objects. As ''Pathfinder'' was NASA's first Mars surface mission to be solar-powered, the effect of Martian dust settling on solar cells were not well understood before the mission.〔 It was predicted at the time that dust particles in the Martian atmosphere would settle on the solar cells powering ''Pathfinder'', blocking sunlight from striking them and slowly causing ''Pathfinder'' to lose power. Since knowing how the settling of dust out of Mars's atmosphere would affect solar cell performance would be critical to subsequent solar-powered missions on Mars, the MAE was included aboard the ''Sojourner'' rover to measure the degradation in performance of a solar cell as dust settled.〔
