Survival Challenges on Mars

The video discusses five lethal hazards on Mars: low atmospheric pressure, a carbon dioxide-rich atmosphere, extreme cold temperatures, Martian dust, and space radiation. Each of these factors poses significant threats to human survival, from immediate effects like suffocation and freezing to long-term dangers such as lung damage and radiation exposure. Understanding these hazards is crucial for future Mars exploration and colonization efforts.

What is the immediate danger to humans on Mars due to its atmospheric conditions?

• Presence of oxygen

• Low atmospheric pressure

• Abundant water vapor

• High atmospheric pressure

Why would a person become brain dead within minutes on Mars?

• High gravity

• Lack of oxygen

• Excessive heat

• Lack of food

What is the temperature on Mars that poses a threat to human survival?

• 80°F

• -20°F

• 0°F

• -80°F

How does Martian dust pose a threat to humans?

• It blocks sunlight

• It clogs the lungs

• It causes skin irritation

• It is radioactive

What is the long-term threat to humans on Mars due to the lack of a magnetic field?

• Dust storms

• Space radiation

• Lack of water

• Extreme cold
