Keeping time on Mars One solar day on Mars, called a “sol,” is about 40 minutes longer than an Earth day, according to the Planetary Society. Watney measures the time he spends stranded on Mars not in days but in “sols,” which is how NASA keeps track of time on Mars in real life.
How many Earth Days is a sol?
While a year on Earth lasts 365 days, every Mars year lasts 668 sols (Mars days) — or 687 Earth days, as each sol lasts a little longer than an Earth day at 24 hours and 39 minutes.
Why are Martian days called sols?
Mars Solar Days and 24-hr Clock Convention 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.
Why does it take 4 years to get to Mars in the Martian?
However, when Watney finds himself stranded, Mars and the Earth are not in a good alignment, and it will take 414 days for supplies to get there! Poor Watney. The increased time is due to two factors: waiting for a desired planetary alignment and the required flight time itself.
Is the Martian a true story?
The Martian, based on a novel of the same name, tells the fictional story of Mark Watney, a US astronaut abandoned on the Red Planet after his crew leave him behind, mistakenly thinking he has been killed in a dust storm.
How long is a year in Mars?
687 daysMars / Orbital period
Since Mars is further from the Sun compared to the Earth, a Martian year is longer: 687 days. That’s just less than two Earth years. Although you wouldn’t age any quicker, living on Mars you’d only be celebrating a birthday roughly every two years, since a birthday is marking another orbit around the Sun.
Can human feces be used as fertilizer the Martian?
So to get biological material into Martian soil, Watney uses the only spare biological material he has: astronaut poop. He mixes it in with the Martian soil, plants some potatoes that NASA had sent up with his crew, and, voila, you have plant life on Mars. Yes, it is possible to grow plants on Mars – kind of.

What does Sol stand for in the Martian?
In The Martian, “sol” is short for “solar day,” and is a term used by planetary astronomers to describe the duration of a solar day on Mars. A sol lasts for 24 hours, 39 minutes, and 35.244 seconds, slightly longer than the equivalent solar day on Earth.
How many hours is a Sol?
Its sidereal day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds. 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.
