How Long Would You Survive on Mars?

The video explores the challenges of human survival on Mars without a spacesuit. It compares Mars to Earth and Venus, highlighting Mars' lower gravity, extreme temperatures, and thin atmosphere. The lack of a magnetic field and the presence of radiation pose significant risks. The low atmospheric pressure on Mars can cause bodily fluids to vaporize, leading to severe physical effects. The video concludes with a reminder to wear a spacesuit and encourages viewers to support and subscribe to Scishow.
