NASA Scientists Fact-Check “The Martian"

Is The Martian unrealistic?

There is the plausible science (using rocket fuel as a source for water) and the downright impossible fiction (Mars sandstorms are not strong enough to cause damage. They're more like gentle breezes.). So while the overall Martian scenario may be fictional, the science in COLL 150 is very real.

What is the biggest error in The Martian?

Factual errors

Due to Mars' low atmospheric pressure, the effective wind pressure in martian wind storms is much lower than shown in the movie, very unlikely to be sufficient to tip a spacecraft. Also, the wind on Mars is much too weak to carry large rocks.

What is the hab made of?

As depicted, the Hab is mostly made out of a canvas material, which is flexible and easily workable. It can be cut and re-sealed, has tremendous tensile strength and can hold air in.

How long is a Martian year?

Video Transcript. The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.

Could Mark Watney have survived?

However, many studies done, and much of scientific research would suggest that Mark Watney could not have survived alone on Mars waiting for the Hermes to rescue him because the emotional, behavioral, and cognitive effects of isolation on an individual are too significant.

Does sol mean day?

A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth. It wouldn't be too difficult to accustom ourselves to the cycle of a Martian day.

How does Watney fix the hab?

He needs to fix the Hab, but in order to do so, he'll need a functional EVA suit, so he'll have to get a new suit before retreating to the rover. Watney decides to roll the airlock closer to the Hab by repeatedly slamming his body against one wall. Overnight, he rolls it within 10 meters of the Hab.

How long is the hab designed to last?

Final answer:

In 'The Martian', the 'Hab' was designed to last for only 31 days. Mark Watney, however, needs to survive about four years on Mars before rescue is possible, thus he struggles to extend the Hab's lifespan.

Could a tree grow on Mars?

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.

What does sol mean in the martian?

A Mars solar day has a mean period of 24 hours 39 minutes 35.244 seconds, and is customarily referred to as a "sol" in order to distinguish this from the roughly 3% shorter solar day on Earth.

How much of the Martian is realistic?

The movie is mostly accurate, but misses the presence of perchlorates in the Martian regolith which meant that Mark Watney would not have been able to grow potatoes in it unless it had been washed in water first to remove it.

Is the MDV from The Martian real?

In the movie there was no MDAV there were two ships- an MAV and an MDV. The MAV was landed on Mars prior to the crew arriving- this way NASA could ensure the ship was functioning before sending the crew to Mars.
