Ummm, who says Mars has no atmosphere? Certainly not NASA. NASA scientists say there is a relatively thin Martian atmosphere consisting mostly of
carbon dioxide (not mon
oxide as said in the OP), with some nitrogen and argon, plus contains traces of oxygen, water, and methane.
Through its space probes, NASA has identified clouds, weather and wind-blown effects such as sandstorms and "dust devils" which are like
mini-tonadoes. There is enough of an atmoshere to keep some of the rusty red dust suspended in it, which causes the "dirty pinkish" color of its
Most of the rocks on Mars are a volcanic rock called basalt, but much of its surface is covered in a fine dust made up of iron oxide (also known as
common rust). Most scientists, including NASA's geologists, think that the iron-rich Mars was once a much wetter place, and the iron in the rocks
reacted with the oxygen in the water to form the iron oxide, or rust.
So the Oxygen to help create the rust (iron oxide) came from the liquid water that probably once flowed on Mars a couple of billion years ago, NOT
from free oxygen floating in space.
