In some regions that have high winds, the winds are as high as 100 meters a second." (That translates to 224 miles per hour, a wind speed well within the range of a Category 5 hurricane on Earth.) He also pointed out that some Martian dust storms can envelop the entire planet, citing the 1971 Mariner 9 mission that couldn't take pictures of Mars's surface for a full month due to an enormous storm that rose 25 miles above the surface, obfuscating nearly everything. "They can come up very quickly on Mars," he told me, "because the atmosphere is so bloody thin that it doesn’t take much. "Our atmosphere can be ferocious and whip things around," he wrote via email, " not likely on Mars."īut Michael Mumma, the founding director at NASA's Goddard Center for Astrobiology, gives the incident a little more room. Jack Mustard, professor of earth environmental and planetary sciences at Brown University, agrees. So while they do get 150 kilometers an hour sandstorms, the inertia behind them - because their air is so thin - it would feel like a gentle breeze on Earth. In reality, Mars' atmosphere is 1/200th the density of Earth's. Even Andy Weir, the author of the original e-book that the movie is based on, acknowledged as much in a recent interview with NPR:
This is a particularly contentious point in the general science of The Martian. They scramble to get back to their ship for an emergency departure - and an errant piece of equipment sends Watney flying into the distance, never to be recovered. The inciting incident is a horrific storm that whips up almost out of nowhere, taking the Ares 3 crew by surprise. 1) The sudden and catastrophic storm that forces Watney's crew to leave him behind
Warning: If you haven't seen the movie yet, this post will spoil specific plot points and, perhaps, their miraculous cinematic luster. Vox reached out to scientists more familiar with Mars, in a bid to better understand the science behind five of The Martian's thrilling twists and outstanding questions. The race to get astronaut Mark Watney (Matt Damon) back from Mars depends on Watney's own ingenuity and the best and brightest scientists on Earth putting their heads together to figure out this seemingly impossible problem. For all the zero-gravity, high-octane action sequences and breathtaking landscapes, the most remarkable thing about The Martian is how it converted scientific problems into thrilling drama.
