But don't let all this stop you from enjoying the movie and/or book. There are plenty of ways for Mars to try to kill us. And in fact, even though the winds of Martian sandstorms probably won't be causing any near-death experiences, sandstorms can be deadly in a different way--via lightning. All those sand particles swirling around together can stir up electric charges that could certainly cause problems for future Martians. "Andy [Weir] has said, 'Had I known that at the time, I could make lightning make this whole thing work,'" says Lavery, adding helpfully, "Meteorites would work, too."
