While Mars's climate has similarities to Earth's, including periodic ice ages, there are also important differences, such as much lower thermal inertia. Mars' atmosphere has a scale height of approximately 11 km (36,000 ft), 60% greater than that on Earth. The climate is of considerable relevance to the question of whether life is or ever has ...
The only difference between spring temperatures and summer temperatures is due to the relatively high eccentricity of Mars' orbit: in northern spring Mars is farther from the Sun than during northern summer, and therefore by coincidence spring is slightly cooler than summer and autumn is slightly warmer than winter.
Mars Pathfinder used the local apparent solar time at its location of landing. Its time zone was AAT-02:13:01, where "AAT" is Airy Apparent Time, meaning apparent (true) solar time at Airy-0. The difference between the true and mean solar time (AMT and AAT) is the Martian equation of time.
During a year, there are large surface temperature swings on the surface between −78.5 °C (−109.3 °F) to 5.7 °C (42.3 °F) [c] similar to Earth's seasons, as both planets have significant axial tilt, Earth at 23.5 degrees and Mars at 25 degrees. Mars was formed approximately 4.5 billion years ago.
Mars climate simulation models date as far back as the Viking missions to Mars. Most Mars climate simulation models were written by individual researchers that were never reused or open-sourced. By the 1990s the need for a unified model codebase came into being, due to the general impact of the internet on climate modelling and research. This ...
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.

MEDA has an increased scope, with greater data collection on Mars dust which contributes to overall Mars program objectives and discovery goals. [4] The instrument suite was developed and provided by the Spanish Astrobiology Center at the Spanish National Research Council in Madrid, Spain. On April 8, 2021, NASA reported the first MEDA weather ...
