Mars has only about 0.7% of the atmospheric pressure of Earth. Mars' atmosphere is about 6.5 millibar, Earth's atmosphere is 1013 millibar. Surface of Mars is like Earth at 100,000 feet (30 kilometres) in the stratosphere. [19] [20] Mars' atmosphere's humidity is 0.03%, Earth's average humidity is about 50% (lowest 0.36%, high 100%).
Badwater Crater is an impact crater located in Hellas Planitia and is situated within the low lying Plain of Peneus Palus on the southern hemisphere of Mars.It contains the lowest currently [as of?] known point on the entire planet, with an elevation of approximately −8,200 metres (−26,900 ft) [2] at 32.79° S, 62.14° E. [1] Badwater has a diameter of approximately 33.14 kilometres (20.59 ...
The atmosphere of Mars is a resource of known composition available at any landing site on Mars. It has been proposed that human exploration of Mars could use carbon dioxide (CO 2 ) from the Martian atmosphere to make methane (CH 4 ) and use it as rocket fuel for the return mission.
The atmosphere expands and contracts as the brightness of the sun at Mars varies by 40% over the course of a Martian year.” That has consequences. Mars and Earth started out with the same ratio ...

The variation in Mars's surface water content is strongly coupled to the evolution of its atmosphere and may have been marked by several key stages. Head and others put together a detailed history of water on Mars and presented it in March, 2023. [300] Dry channels near Warrego Valles.
Liquid water cannot exist on the surface of Mars with its present low atmospheric pressure, except at the lowest elevations for short periods. [ 61 ] [ 62 ] Results published in the journal Science after the mission ended reported that chloride, bicarbonate, magnesium, sodium potassium, calcium, and possibly sulfate were detected in the samples.
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life. ‘Black Beauty’ was found on ...
