How strong is the gravity on Mars? - Phys.org
WebLike Earth, Mars has an atmosphere and weather, but both differ greatly from what we experience on Earth. Let's compare: The composition of the Martian atmosphere differs greatly from Earth's. Earth's atmosphere is 78% nitrogen, 21% oxygen, 1.0% argon, 0.04% carbon dioxide, and small amounts of other gases. It also averages about 1% water vapor.
