The first crew that touches down on mars and spends an extended period of time there will go insane
>The Antarctic winter is a period of little to no sunlight, no physical contact with other continents or Antarctic stations, including no airplanes, ships, or mail. The area has the driest desert climate on Earth, a low air pressure, and an oxygen-poor atmosphere. It is completely cut off during winter, with a mean temperature of −51 °C (−60 °F), and the lowest recorded temperature is −85 °C (−121 °F). For these reasons, the immobility, monotony, harsh physical environment, sexual deprivation, and the general isolation are believed to contribute to increased anxiety and depression among the residents of Antarctic stations.
>Symptoms: Depression, insomnia, hostility, anger/irritability, diminished cognitive performance, mild hypnotic states, irritable bowel syndrome
If Antarctica breaks people imagine what Mars with its toxic atmosphere, scarce water, colder temperature and radiation will do to people
