Could Humans Survive on Mars?

It seems like everyone has Mars on the mind these days. NASA wants to send humans to the red planet by 2030, and SpaceX wants to get there even sooner, with plans to have people there by 2024.

Mars is a favorite theme in Hollywood, with movies like The Martian and this year’s Life exploring what we might find once we finally reach our celestial neighbor, but most of them aren’t addressing the biggest questions — once we get there, how will we survive long-term?

The atmosphere of Mars is mostly carbon dioxide, the surface of the planet is too cold to sustain human life, and the planet’s gravity is a mere 38% of Earth’s. Plus, the atmosphere on Mars is equivalent to about 1% of the Earth’s atmosphere at sea level. That makes getting to the surface tricky.
