The climate of Mars has been a topic of scientific curiosity for centuries, ... meaning its angle changes over time.) [121] [122] [123] ...
The atmosphere of Mars is colder than Earth’s owing to the larger distance from the Sun, receiving less solar energy and has a lower effective temperature, which is about 210 K (−63 °C; −82 °F). [2] The average surface emission temperature of Mars is just 215 K (−58 °C; −73 °F), which is comparable to inland Antarctica.
Temperatures on Mars from REMS on the Curiosity Rover (August 16/17, 2012). Rover Environmental Monitoring Station (REMS) is a weather station on Mars for Curiosity rover contributed by Spain and Finland. [1] [2] REMS measures humidity, pressure, temperature, wind speeds, and ultraviolet radiation on Mars. [3]
The results showed that the night time temperature on Mars dropped to −85 °C (−121 °F), indicating an "enormous diurnal fluctuation" in temperatures. [76] The temperature of Martian clouds was measured as −30 °C (−22 °F). [ 77 ]
On Mars, radiometric ages are not available except from Martian meteorites whose provenance and stratigraphic context are unknown. Instead, absolute ages on Mars are determined by impact crater density, which is heavily dependent upon models of crater formation over time. [31]
These measurements reflect averages over a large region and so are lower than the maximum point surface temperature. [ 6 ] Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at 81°48′S 59°18′E / 81.8°S 59.3°E ...
The idea would be to augment the natural greenhouse effect on Mars to raise its surface temperature by roughly 50 degrees Fahrenheit (28 degrees Celsius) over a span of a decade.
As on Earth, Mars experiences Milankovitch cycles that cause its axial tilt (obliquity) and orbital eccentricity to vary over long periods of time, which has long-term effects on its climate. The variation of Mars's axial tilt is much larger than for Earth because it lacks the stabilizing influence of a large moon like Earth's Moon. Mars has a ...
