 When Weir wrote the novel The Martian, he strove to present the science correctly and used reader feedback to get it right. When Scott began directing the film, he also sought to make it realistic and received help from James L. Green, the Director of the Planetary Science Division at NASA's Science Mission Directorate. Green put together teams to answer scientific questions that Scott asked. Green said, "The Martian is reasonably realistic", though he said the film's hazardous dust storm, despite reaching speeds of 120 miles per hour (190 km / h) would in reality have weak force. Green also found the NASA buildings in the film to be more stylish than the functional ones NASA actually uses. Film critics picked up the point that the Martian winds could amount to "barely a light breeze" in their reviews, and screenwriter Goddard agreed the winds had to be considerably exaggerated in order to set up the situation that sets the story in motion.
