The dunes of Mars are almost free of their seasonal ice cap due to the arrival of the Martian summer, some ice foci can still be seen in the areas protected by the shade.
After seven months of a 480 million kilometers, NASA’s Perseverance rover will land over Jezero Crater on Mars this Thursday.
After penetrating the atmosphere of the red planet at high speed, a gigantic parachute will stop the ship and some retro rockets will stabilize the platform a few meters above the ground to deposit the rover thanks to a rope system: this will last 7 minutes.
The rover’s main mission is to search for traces of past life on the red planet. Experts hope to find fossils of bacteria or microbes.
The axis of Mars is tilted 25.2º, an inclination very similar to that of the Earth’s axis. Therefore, the seasons of both planets are very similar.
An important difference is that since the year on Mars lasts 687 days, the seasons are almost twice as long.
Another influential factor for the manifestation of the seasons is the elliptical orbit of Mars, which makes the northern hemisphere more temperate than the southern hemisphere.
Summers in the south are hot and fast, while winters are cold and long.
During the Martian summer the hottest moment can reach temperatures of up to 20ºC during the day and drop to -80ºC at night.
However, the change from one season to another is not very noticeable. With some exceptions such as the variation in the size of the polar ice caps or the greater presence of dust storms during the summer.
