Terraforming of Mars

Pekka Janhunen

Mars also features a history of being wet and plush. It has been theorized that when it had been first formed 4.2 billion years ago it had an environment and high amounts of water. Since Mars is far smaller than Earth, its internal core gradually hardened, which caused Mars to lose its magnetic flux? Without a protective magnetic flux, the solar radiation was ready to strip away most of the Martian atmosphere. The end result's that over subsequent 500 million years, Mars gradually transformed from a warm, wet planet to a chilly, dry planet. Around 3.7 billion years ago, Mars eventually became almost like the barren planet we all know of today. Despite this, there's evidence that water still exists on Mars. Water in the form of ice has been found at the poles and underground in the Utopia Plantain region of Mars. There is up to five million cubic kilometers of ice on Mars, and if this were to be spread evenly over everything of the surface of Mars it would submerge the planet under 35 meters of water.
