The atmosphere of Mars differs from Earth's in many ways, and most of them don't bode well for humans living there.
It's composed mostly of carbon dioxide (95.3 percent compared to less than 1 percent on Earth).
- Mars has much less nitrogen (2.7 percent compared to 78 percent on Earth).
- It has very little oxygen (0.13 percent compared to 21 percent on Earth).
- The red planet's atmosphere is only 0.03 percent water vapor, compared to Earth, where it makes up around 1 percent.
- On average, it exerts only 6.1 millibars of surface pressure (Earth's average sea-level atmospheric pressure is 1,013.25 millibars)
Because the "air" on Mars is so thin, it holds little of the heat that comes from the ground after it absorbs solar radiation. The thin air also is responsible for the wide, daily swings in temperature (almost 100 degrees Fahrenheit or 60 degrees Celsius)
