The Atmosphere and Weather

What is Mars atmosphere made of?

The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide. Here's a breakdown of its composition:

  • Carbon dioxide: 95.32 percent
  • Nitrogen: 2.7 percent
  • Argon: 1.6 percent
  • Oxygen: 0.13 percent
  • Carbon monoxide: 0.08 percent
  • Also, minor amounts of: water, nitrogen oxide, neon, hydrogen-deuterium-oxygen, krypton and xenon


So now the Mars atmosphere is very thin, the temperature is very cold, and what water remains is either frozen in the Martian poles as permafrost or hidden in deep underground springs. Mars' current climate changes drastically during the year. It has seasons similar to the Earth's due the tilt of its axis.
