Terraforming of Mars

Andrea Vittori 5D

nowadays discovery of new planets with similar features to Earth

one is near to is and really interesting for us

Introduction:

2

manreally the only living being in the universe

the Earth, was the only habitable planet

What does “terraforming “ means?:

hypothetical process

climate, surface, and other features

aim making large areas more hospitable to human setting

3

Mars:

4

Mars fourth of our solar system, near the Earth

different and common features

same surface features

½ the speed of Earth

½ smaller

day is 24 hours long

features unfavorable to life

differences from our planet

thin atmosphere

temperature between -140 º C and 20 º C

no atmospheric events

presence of water on its surfaceBUT

5

The power of water:

water essential element for life

series of observations for a future conquest

average atmospheric temperature that is below 0 no liquid state

but in the form of huge icebergs

to the two poles

6

Is it possible to have a second “Earth”?:

lifeatmosphere and a climate similar to Earth

use of the water trapped in icebergs

melt them with large mirrors

326 km of diameter (200 miles)

positioned in the space around Mars

reflect sun rays exactly on the poles of the planet

sun

icebergs

CO2

plants

oxygen and water vapor

rivers, lakes and oceans

primordial atmosphere

The creation of a new “home”:

clouds

weather events

8

problem of low temperature and UV rays

clouds

absorb a great part of them

the heat will be retained and the temperature will be constant

atmosphere and constant temperature:
