DO YOU WANT TO BE COOL, LIGHTER, AND YOUNGER?
The surface area of Mars is equal to the amount of land on earth.


Average temp. of -80º
Second smallest planet
Tilted at 25.19º- same as earth
Gravity is 62% of Earth's. Lighter
A Martian day 24hrs & 40mins
Mars travels 4 miles/sec slower than Earth

There isn't life on the surface and if there is life, it's not big animals, it would have to be microscopic life life bacteria. The bacteria would have to live under Mars' crust or at the north or south poles. We're unsure of what Mars looks life underneath its' crust. The life could be getting energy from the possibly molten core and water that had been absorbed into the soil.

HEAT

WE'RE EXPERTS
100 years to heat Mars. Heat would release the carbon dioxide in the soil to absorb the sun's heat further. This would also pressurize mars. No more space suits. Just oxygen
