Sep 28, 2015 · “But a 100 mph wind on Mars, because the atmosphere is so thin, has the same inertia and dynamic pressure down at the surface as about an 11 mph (18 km/h) wind on Earth.

Sep 30, 2015 · Astronauts would be exposed to two kinds of dangers as they traveled to and from Mars and worked on the surface: solar energetic particles and galactic cosmic rays. A one-way, 180-day trip alone...
Jan 23, 2024 · The movie did an excellent job of portraying space travel accurately. Unlike most other space movies prioritizing dramatic effects over realistic depictions of space journeys, The Martian got it right by showing that it would take approximately eight months to reach Mars using current technology.

Oct 5, 2015 · In just its opening weekend, director Ridley Scott’s The Martian, which hit theaters last week, pulled in over $100 million worldwide. The film follows Mark Watney (Matt Damon), an astronaut NASA accidentally left behind on a recent mission to Mars, as he tries to survive on the harsh planet. Scientists have hailed the film as one of the most ...

The temperature on Mars is shown in Celsius, but here in America, we’re used to the temperature being in Fahrenheit. Mars has a wide range of temperatures, but mostly just really cold. Real Mars temps get as frigid as -242.4 degrees Fahrenheit and as warm as 71.6 degrees Fahrenheit.
The air is 95 percent carbon dioxide, so good luck with visiting without a fancy spacesuit designed to provide oxygen.
While NASA just announced that it has credible evidence that liquid water exists on Mars, it’s still unknown if there is enough to rely on as a resource. Mars is drier than any of the driest deserts on Earth, but just under the planet’s surface is ice that can be heated up and turned into water.
The work sol is used by planetary astronomers to refer to one single solar day on Mars. Surprisingly, their days are very similar in length to those on Earth. A Mars sol lasts 24 hours, 39 minutes, and 35.244 seconds.
It couldn’t happen because Mars has super low atmospheric pressure (less than 1 percent of Earth’s), which means a severe storm would feel like a soft summer breeze. Andy Weir, who wrote the novel, The Martian, said this about the unrealistic storm, “I needed a way to force the astronauts off the planet, so I allowed myself some leeway. Plus, I tho...
The Mars Ascent Vehicle called Hermes was named after the ancient Greek messenger of the gods. Though NASA doesn’t currently have any long-term space travel vehicles, it’s plausible one could look like the Hermes, but it would most likely be a lot more compact.
Everything on Mars is powered by solar panels. This is very realistic, considering this is how the power on the International Space Station is generated.
“EVA,” or Extra Vehicular Activity, where scientists would work outdoors, would certainly require its own suit for conducting zero-gravity activities. Director Ridley Scott called the costume the “doughboy” because it was so puffy. More: 13 Mind-blowing things in Trainspotting you never noticed
In the film, Watney (Matt Damon), uses packages of human poop to add bacteria to the Martian soil so he can grow potatoes. Thanks to real experiments conducted by Mars Rovers, we know the soil on the red planet already contains nitrogen in a biologically usable form, but farmers in China have been using human feces as a fertilizer for centuries. Mo...
Because of galactic cosmic rays in space, the trip to and from Mars would expose the astronauts to more than 30 times the annual radiation limit for a nuclear power plant engineer. Some scientists believe this would severely shorten the lives of Mars visitors. The Martianopens in theaters on Oct. 2.
Oct 22, 2015 · In the new Ridley Scott sci-fi blockbuster The Martian, Matt Damon plays botanist Mark Watney, who gets stranded on Mars after a ferocious sandstorm forces his crew to abort their mission and blast off for Earth. Watney survives through scientific derring-do, figuring out, for instance, how to grow potatoes with his own human waste.
