Mars lost its magnetosphere 4 billion years ago, so the solar wind interacts directly with the Martian ionosphere, decreasing atmospheric density by destroying the outer layer of atoms.
Compared with Earth, Mars's atmosphere is quite thin.
Pressure at the surface varies from a minimum of 30 Pa (0.030 kPa) on Olympus Mons to over 1155 Pa (1.155 kPa), at Hellas Planitia, with a mean pressure at the surface level of 600 Pa (0.60 kPa ). The most dense pressure on Mars, is equal to the pressure found 35 km above the Earth's surface.
Although Mars was at opposition on March 3 when it was most likely that this planet to be at its best seeing, it seems that on March 24 atmosphere was much clearer, and these are my best images with the red planet so far.
