Map shows what Mars would look like if it were covered by oceans

A student from Nepal created a map that shows what Mars would look like if it had 71% of its surface covered with water, as it does on Earth. The result would be two large continental masses, one crowned by Mount Olympus, the largest volcano in the solar system.


Aasitya Raj Bhattarai, a civil engineering student at Tribhuvan University in Kirtipur, Nepal, created the map as part of a project that calculates “the volume of water needed to make life on Mars sustainable and the sources needed for this volume, originally of comets that will pass near Mars in the next 100 years “.

On the map of Bhattaraj the sea is represented in shades of blue, and the average level is 1,211 meters below the level of the “geide”, an average of the ocean surface calculated by removing factors such as tides and sea currents. Continents start in a greenish tone (with altitudes starting at 1,211 meters), which progresses to brown, white and purple, the higher the altitude. The top of Mount Olympus, which is more than twice the height of Everest, would be 20,076 meters above sea level.

Earth 2.0?

Terraform Mars, transforming it into a habitable planet, one of Elon Musk’s great dreams. In 2015, the billionaire proposed the use of nuclear bombs as the easiest way to heat the poles of the planet, causing the melting of millions of tons of ice and carbon dioxide and profoundly altering the Martian climate.

Carbon dioxide would increase the pressure of the Martian atmosphere, facilitating the existence of liquid water on the surface. In addition, just like on Earth, it would increase the average temperature of the planet, making the climate milder for terrestrial organisms.

Before that Musk wants to use his Starship, a spacecraft currently under development by SpaceX, to create a colony on Mars with up to 1 million inhabitants by the year 2050.

For that, SpaceX would have to build 100 Starships per year, for a total of 1,000 ships over 10 years, and make three daily launches, each carrying more than 100 tons, for a total of 100 thousand tons / year. This would be done each time the Earth and Mars become closer, which happens once every 26 months.

To put this in perspective, the executive points out that, if we consider all of the spacecraft currently in operation, the total payload capacity of only 500 tons per year – with the Falcon series rockets representing about half of that.
