How does Mark grow food in The Martian?
In the bestselling sci-fi novel and upcoming movie “The Martian,” astronaut and botanist Mark Watney survives on Mars for over a year, largely thanks to his ingenious potato crop. In “The Martian,” Watney grows his own food by planting potato eyes in the ground.
Can you grow potatoes from poop?
ANSWER: Manure is an excellent amendment for soil where potatoes will be grown, as long as the manure is not fresh. If you’ve added manure to the compost heap, you should apply it to your garden soil before you plant potatoes. Spread manure out over the area where potatoes will grow in a layer one or two inches deep.
How did The Martian grow potatoes?
In The Martian, potatoes are successfully harvested after 48 sols (a Martian solar day – 24 hours 39 minutes long), but the success of the venture does not last: Watney’s potato-growing is put to an abrupt end as the front of his habitat blows off, exposing his entire crop to the Martian air.
Where does Mars grow their food?
In light of the complexity of soil, Mars colonists may instead opt to use higher-tech soil-free methods, such as hydroponics and aeroponics. Instead of plants’ roots absorbing nutrients from the soil, the roots are immersed in nutrient-laden water (hydroponics) or in a mist of nutrient-rich water (aeroponics).
How does Watney make water?
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. They must water their potatoes and keep track of how much water they administer and how often.
Can a potato grow on Mars?
Potatoes can grow in ‘extreme’ Mars-like conditions, a new NASA-backed experiment shows. Mark Watney, played by Matt Damon, survives by fertilizing Martian soil with his feces, slicing potatoes, and planting the cuttings in the soil. This eventually grows him enough food to last hundreds of days.
Where does Mark Watney grow potatoes?
But Watney didn’t grow potatoes in full Martian conditions. He grew them in a human habitat with water, oxygen, and other amenities found on Earth. He just happened to use Martian soil for the bulk of his growing medium.
What plant can grow on Mars?
The students found that dandelions would flourish on Mars and have significant benefits: they grow quickly, every part of the plant is edible, and they have high nutritional value. Other thriving plants include microgreens, lettuce, arugula, spinach, peas, garlic, kale and onions.
Can Martian soil grow crops?
Fertilizing Mars Research suggests Martian soil has some of the nutrients plants need to grow and survive (see “Plants’ Nutrients,” right). When soils are rich in nutrients—such as nitrogen, phosphorus, and potassium—crops grow well.
How did Mark Watney grow potatoes on Mars?
Mark watney had some potatoes in the base camp. As being a Botanist he had great plant knowledge. He used his stool to make the Martian soil fertile. The Martian soil though has iron but is not fertile so for manure he grows potatoes in his own stool. The Rock reveals the best success hack everybody needs to try.
How does NASA get food on Mars for Thanksgiving?
By slowly adding Martian soil to his Earth soil, he achieved viable soil with the needed bacteria. The Ares III crew was going to be on Mars for Thanksgiving, so he had a dozen potatoes that were meant to be cooked for their Thanksgiving meal. NASA gives crews special food for holidays. [ 1]
How did Mark Watney make the Martian soil fertile?

How does Watney get back to Mars?
The crew does not leave in the same ship they arrive in; they leave in the MAV, which is already on-planet. The Chinese rocket is not used as a booster to propel the Hermes. It contains necessary supplies to sustain Watney (and the crew of the Hermes). The Hermes is able to return to Mars via a gravity slingshot.
