'Often on Mars, the exact opposite is seen: large flat low areas are more wind-scoured, removing fine materials and leaving rocks and eroded bedrock'. 'People commonly assume that smooth at large scales (kilometres) means smooth at small scales (meters to tens of meters). 'When our hero travels into Arabia Terra it is described as much rockier than Acidalia, but the opposite is generally true: much of Arabia is dust mantled and smooth at the scale of a rover,' says Nasa. In an attempt to leave the planet, Watney drives 3,200km (2,000 miles) to Schiaparelli crater when a subsequent mission, Ares 4, lands there in four years.
This isn't the only region in the film that is less than accurate.
Meanwhile, fields of secondary craters suggest that the surface is extremely rough at scales that near the size of the rover. There are also fissures in the ground, creating steep cliffs that would be impassable. Most of the action in the Hollywood blockbuster 'The Martian' is set at the 'Ares 3' site in on Mars' southern Acidalia Planitia. The film depicts Acidalia as flat landscape that's smooth enough for stranded astronaut Mark Watney to drive over with relative ease. The image shows how much of Acidalia Planitia is covered by fields of boulders that can reach up to several metres in height, making driving a rover in this area difficult. Weir recently provided Nasa with the exact coordinate of his protagonist's location. He requested that the space agency take an image of the real thing, and they agreed.

Huge outflow channels tell the stories of floods in Mars' distant past, when water flowed across its surface.Īnd, if you have a 3D printer to hand, the map provides details of how to print out various features on the red planet. Other notable features on the map include Valles Marineris, a canyon that runs across one fourth of Mars' surface and measures about 90 miles (150km) wide.Īcross the map, gigantic rift valleys fracture the surface over vast distances. Mars Trek is one of Nasa's planetary mapping and modeling web portals.Īs well as Warney's journey, it also provides detailed views of landmarks such as Olympus Mons, the largest-known volcano in the solar system, measuring more than 15 miles (24 km) above its surrounding surface. The bookmark's 3D view lets you fly along Watney's path at user-selected speeds, stopping along the way and panning across the remarkable terrain.
The bookmark's 2D view provides an overview of the path of Watney's odyssey and critical points of interest along the way.
