Oct 2, 2015 · In "The Martian," astronaut Mark Watney uses NASA's old Mars Pathfinder lander and Sojourner to phone home to Earth. Here's what the movie gets right.

In the movie, Watney lives in "the Hab", a space habitat designed to temporarily house astronauts on Mars. The Hab is based upon a similar habitat currently in development at NASA called "HERA" (Human Exploration Research Analog). HERA is designed to house astronauts on longer space missions for 14 days, with plans to boost that time to 60 days in ...
If Watney's going to survive for four years in a place without any food, he's going to have to figure out a way to grow some. And that's just what he does; he grows a field of potatoes within his habitat. In real life, actual astronauts have recently grown lettuce aboard theISS using a system called Veggiethat uses different colored LED lights and ...
Mars obviously doesn't have the atmosphere of Earth, so Watney has to figure out a way to get oxygen or else he's not going to last very long on the planet. He uses an "oxygenator" to create oxygenfrom the carbon dioxide released from the fuel in his Mars Ascent Vehicle. Astronauts aboard the ISS use a similar system, called the Oxygen Generation S...
Watney obviously needs to drink water, and last I checked Mars wasn't overflowing with the stuff, so he'll need to recycle his H2O. Aboard the ISS, astronauts already use a water recovery systemthat turns every drop of used water, sweat, and even urine into drinkable water. Yum!
In order to make water, oxygen, and food, Watney needs power, which he generates using a Radioisotope Thermoelectric Generator, a device that uses decaying plutonium to create electrical power. They're already in use in the current Mars rover, Curiosity, which is how the little fella has the power to send back his adorable melfies (Mars selfies).
Surviving on Mars is obviously a huge chunk of the movie, but there's also the major hurdle of traveling back and forth from the planet. The Hermes ship used in the movie utilizes ion propulsion, a system that electronically breaks down gases and pushes them out at high speeds to create slow momentum that builds over time. It's one of the most fuel...
