Changes in solar radiation result in pronounced diurnal variations in the atmosphere due to the very low surface pressure of only 4 mbar. Temperatures can fluctuate significantly during the day, ranging from -125\u00b0C to +35\u00b0C. Furthermore, Mars lacks oceans like Earth, which could buffer these temperature changes. The Mars axis of rotation is tilted at approximately 25\u00b0, similar to Earth, leading to seasons on Mars. These seasons vary in duration and intensity due to Mars' highly elliptical orbit around the sun. A substantial portion of the atmospheric carbon dioxide (~30%) condenses over the polar caps during the winter hemisphere's very low temperatures and sublimates in the following spring.<\/p>\n\n\n\n<p>Periodically, the entire planet experiences global dust storms caused by high atmospheric variability and low atmospheric pressure, lasting for weeks. These dust storms induce significant changes in Mars' global climate.<\/p>","protected":false},"excerpt":{"rendered":"<p>Die Mars-Atmosph\u00e4re Heutzutage wird der Mars durch seine extrem d\u00fcnne, trockene und kalte Atmosph\u00e4re charakterisiert, die haupts\u00e4chlich aus Kohlendioxid besteht.
