Mars, the mysterious red planet, has been the subject of study for centuries. As scientists explore this distant world, they discover evidence of a rich and complex geological history.

Noah’s Age: The Early Days of Mars: The Noachian Era, named after the crater Noachis, is the oldest of the Martian geological eras. It is thought to have occurred approximately 4.1 to 3.7 billion years ago. During this time, Mars experienced intense meteorite bombardment and active volcanism, which left their mark in the form of impact craters and extensive lava plains.

Hesperian Era: The Age of Volcanoes and Valleys: The Hesperian Era, spanning from about 3.7 billion years ago to 3 billion years ago, witnessed intense volcanic activity on Mars. Large volcanoes, such as Olympus Mons, arose during this period, along with the formation of extensive valley systems, such as Valles Marineris, which are thought to have been sculpted by tectonic and fluvial activity.

Amazonian Era: The Change to a Cold and Dry Climate: The Amazon Era, which began approximately 3 billion years ago and continues to the present day, marks a change in Mars’ climate and geology. During this time, the planet experienced gradual cooling and most of the surface water was frozen or lost to space. Although volcanic and tectonic activity decreased, some active geological processes, such as landslides and wind activity, are still observed.

Exploring Mars in the Modern Era: In the modern era, robotic exploration of Mars has revealed fascinating details about its geology and evolution. Missions such as NASA’s Mars rovers Curiosity and Perseverance have explored craters, valleys and mountains, revealing clues about the history of water on Mars and the possibility of past or present life.
