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 Martian atmosphere is composed mainly of carbon dioxide and has a mean surface pressure of about 600 pascals (Pa), much lower than the Earth's 101,000 Pa. One effect of this is that Mars' atmosphere can react much more quickly to a given energy input than Earth's atmosphere. [51]
The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) [1] was a technology demonstration on the NASA Mars 2020 rover Perseverance investigating the production of oxygen on Mars. [2] On April 20, 2021, MOXIE produced oxygen from carbon dioxide in the Martian atmosphere by using solid oxide electrolysis .

The Mars Global Surveyor, launched on November 7, 1996, has been an effective spacecraft that has orbited and measured the surface of Mars thousands of times. Among the various instruments on the Mars Global Surveyor, the Mars Orbiter Laser Altimeter (MOLA) and Thermal Emission Spectrometer (TES) are used to map the topography of Mars and study the surface and atmosphere of the planet.
The idea of transforming Mars into a world more hospitable to human habitation is a regular feature of science fiction. Scientists are now proposing a new approach to warm up Earth's planetary ...
[17] The 2011 edition of the same textbook noted that "Albet Yen of the Jet Propulsion Laboratory has shown that, under extremely cold and dry conditions and in a carbon dioxide atmosphere, ultraviolet light (remember: Mars lacks an ozone layer, so the surface is bathed in ultraviolet) can cause carbon dioxide to react with soils to produce ...
Video of descent and touchdown of Perseverance. Mars atmospheric entry is the entry into the atmosphere of Mars. High velocity entry into Martian air creates a CO 2-N 2 plasma, as opposed to O 2-N 2 for Earth air. [1] Mars entry is affected by the radiative effects of hot CO 2 gas and Martian dust suspended in the air. [2]
