Transcript of LIFE ON MARS

LIFE ON MARS
Earth and Mars
Gravity :
9.78N
3.69N
Temperature :
15°C
-53°C
150.10^6km
228.10^6km
Distance from
Sun :
Atmosphere :
carbon dioxide
- of 1%
95.3%
diazote
78%
2.7%
0.13%
21%
dioxygene
Why would we want to
live on other worlds?
Survive asteroid attacks
Population growth
Develop new technologies
For the challenge and adventure
But why Mars ?

Close to earth
Warmth
Length of day
Seasons like on Earth
Ressources
Potential for terraforming
The challenges of living
on Mars
Cold
High radiation
Low gravity
Very thin and toxic atmosphere
Solid water
What will we need on Mars ?
Physical needs :

- Water
- Air
- Food
- Warmth
- Sunshine
- Clothing
- Buildings
Technological needs :
- Electricity
- Materials
- Tools
- Computers
& communications
- Vehicles & fuel
- Robots
WATER
Plenty of water but...
Ice harder than rock
Solutions :
Heat up the ground
Recycle
AIR
Earth :
20% of 02
80% of N2
We can make air like this on Mars!!!
Solution :
N2 from Mars' atmosphere

O2 from CO2, H20

Recycle using plants (=photosynthesis)
FOOD
Mars' dirt :
Not suited for life
Solutions :
Food grown in sealed greenhouses

Hydroponics

Aquaponics

Chicken and eggs


CLOTHING
Solution :
Hemp
useful for :
- Cloth
- canvas for shoes, bags
- Rope
- Plastics
- Hemp oil
BUILDINGS
Biggest problem :
Radiation
Solutions :
Surfaces structures

Pile dirt on the roof

Underground
Protection from radiations
+ easier to keep warm

Domes
Plastic and glass (maybe infatable)
MATERIALS
Solutions
Mars covered in iron

Make steel using carbon from atmosphere

Make bricks concrete, glass
and plastic from local plants
ELECTRICITY
Solutions :
Nuclear ?
Would have to find uranium

Sunlight ?
Possible but less sunlight on Mars

Wind ?
YES!! Lots of wind of Mars !
VEHICLES AND FUEL
What sort of vehicles ?
- Quad bikes
- Gliders, planes, balloons
- Rockets, spaceships
Solution :
Good fuel = methane (CH4) + dioxygen (02)
We can make it from Mars' ground and water
ROBOTS
Role :
- Digging
- Mining
- Construction
- Exploration
- Transportation
Solutions :
Electronics
From Earth


Bodies
Imported from Earth / made on Mars

Software
Earth / Mars
Pollution
What will we need to bring from Earth?
Health and fitness
Terraforming
Electronics, computers and communications gear

Machinery, motors, tools

Solar panels, windmills

Cooking equipment

Games, books, musical instruments
Low gravity
Strength training
High radiation
Stay inside
(during solar flares)
What is it ??
Temperature
rise
Importation
of Nitrogen
Expansion of
hydrosphere
Growth of
atmosphere
Construction of
biosphere
Warming Mars
Create global warming
Adding Nitrogen
2 solutions :
Adding life
Warmth + liquid water
Life can grow
And maybe...
Genetic engineering
Building a biosphere
4 steps :
Resistant microbes
Aquatic plants
Aquatic animals
Plants on land + animals
Do you want to go to mars ??
You will need :
Some scientific knowledge
Good health and fitness
Good people skills
A range of interests
Good things to study :
Engineering, sciences, medicine, technology
Electronics, robotics
Metalworking trades, mechanics
PFC's
