What is wrong with the science in the Martian?

What is wrong with the science in the Martian?

Inaccuracies in the book and movie Although Mars does get dust storms, the atmospheric pressure is so low that the wind is negligible, although the dust itself can be harmful. Andy Weir admits the dust storm was used simply to move the plot along and leave Mark Watney stranded on Mars.

How scientifically accurate is the Martian?

Science of The Martian: How Scientifically Accurate Is ‘The Martian’? The Martian, starring Matt Damon, was quite scientifically accurate. Growing potatoes on Mars can be feasible as the basic mineral content of the soil is adequate, the shelter shown in the movie is quite realistic too.

What were some challenges to making growth possible in the Martian?

Some conditions would make it difficult for plants to grow on Mars. For example, Mars’s extreme cold temperatures make life difficult to sustain. Sunlight and heat reaching that planet is much less than what the Earth gets. This is because Mars is about 50 million miles farther away from the sun.

Is it possible to create water like in The Martian?

There’s also the problem of hauling up water, which has yet to be found in plentiful liquid form on Mars. In “The Martian,” Damon’s character, astronaut Mark Watney, produces water by burning leftover rocket fuel and extracts the hydrogen from the resulting chemical reaction.

What are the next two problems Watney faces?

The first major problem Watney faces is getting stranded and wounded on Mars. The second problem Watney faces is how he is going to survive on mars till help can come. The final problem he faces is how is he going to get to the Ares, so he can leave Mars.

What challenges do scientists face when growing plants in space?

Growing plants in space is tough — low gravity means water distribution is difficult to manage, the roots are often starved of oxygen, and stagnant air reduces evaporation and increases the leaf temperature.

What does NASA think of The Martian?

Despite a few inaccuracies, “The Martian” still comes astronaut-recommended. NASA astronaut and potential Mars candidate Victor Glover said “The Martian” is now on the shortlist of “recommended reading” around the astronaut office, Mashable reported.

Why did Watney cut a hole in the rover?

He drilled holes into the top and put a ‘balloon’ in it in order to make the right conditions for the oxygenator and to make it bigger. Watney also salvaged the power cells from the abandoned Rover 1 to double the power lifespan of the Rover 2.

Can human feces be used as fertilizer the Martian?

To avoid this, says Bugbee, Martians will have to compost the feces over several months to weed out the bad microbes. So it’s possible to use human waste for fertilizer, but they’d better have a contingency plan for the first few months.

Is Martian soil toxic?

Toxicity. Martian soil is toxic, due to relatively high concentrations of perchlorate compounds containing chlorine. Elemental chlorine was first discovered during localised investigations by Mars rover Sojourner, and has been confirmed by Spirit, Opportunity and Curiosity.

Why is Martians fire weak?

Despite his great power, which often rivals Superman, Martian Manhunter has a most common weakness: fire. This fear is the result of manipulation of the Martians by the Guardians of the Universe in the distant past; the Martians were once composed of fire – they used it to reproduce.

What are the challenges that Mark Watney faced during his stay on Mars?

Why can’t astronauts bring real food to space?

The salt and pepper would simply float away. There is a danger they could clog air vents, contaminate equipment or get stuck in an astronaut’s eyes, mouth or nose. Astronauts eat three meals a day: breakfast, lunch and dinner.

Why is it difficult to grow plants in space?

The first challenge in growing plants in space is how to get plants to grow without gravity. This runs into difficulties regarding the effects of gravity on root development, providing appropriate types of lighting, and other challenges.

While The Martian is scientifically accurate during some parts of the movie, Ridley Scott’s sci-fi takes speculative liberties with other scenes. The Martian is one of those sci-fi films that appears to be highly-technical and factual to a regular person, but the flaws in its treatment of science would make a real NASA engineer roll their eyes.

Is the Martian a good movie about science?

The Verdict: A-. The Martian isn’t a documentary of 100% accurate science, but it’s plausible and mostly consistent. A few moments strain credibility to snapping and some science is distinctly plot-triggered, but this is a story where physics plays a starring role and it shows.

Is space travel in the Martian Just science-fiction?

That, coupled with the fact that Mars has only 30% of Earth’s gravity, means that space travel in The Martian is still just science-fiction. The Martian is the perfect example of Murphy’s law: anything that can go wrong, will go wrong.

What can we learn from the Martian?

Give The Martian props for getting the botany mostly right. Martian soil would, as in the story, be suitable for growing crops—and in at least one study it worked better than ordinary Earthly dirt. And Watney’s use of stored human waste as fertilizer would indeed make the reaping richer—even if it made the sowing nastier.
